Advantages of optical storage media.

I. Summary.

Have a question, we live in an age of information, it is not. Focus shifted to the global economy from manufacturing to the importance of physical data, statistics, facts, figures, numbers and record a higher Value in the business world. This shift is even more the importance of information in the company. escalated almost all information that the professional associations in electronic form, and an increase in value and volume of data is not sufficient demand for storage space for his homeland.

Solution? Storage.

It is a variety of information and percentages are more maintained. Only 25% of data within an organization recently created, the rest is redundant data or data in the past created and is maintained for reuse in the future.

This situation has a demand for data storage needs of financial worries and logistics both. Storage that help organizations. Effectively treat the mass of the redundant data is often a very long time to be able to access it if necessary.

II Why collect?

If necessary. Put it simply an organization of electronic information valuable assets and must always remain. In today's fast-paced world. Inventory data is not luxurious. Efficient and reliable. And archiving technology at an affordable fast Need to use a lot of content.

Data Warehouse enables organizations to achieve the three experts. The primary target.

• • Protect and store data for future
• • Storage related increases in the world. Must
• • in the implementation of the world and the needs of law

Prevention and treatment. Information for future

Medical records from the contract documents to employees of corporate communications you spend much time and energy to create. Management and treatment of electronic documents.

Result of the influx of electronic information and its importance to the. Considerable amount of information. Company holds. A special significance.

After the electronic data and documents have been created, it must be managed and protected. To protect the data of key technologies and practices. Must be available to help organizations). Prevent loss, destruction and failure, and b). Continue to be useful and cost-effective if the data in contact stands. Devastating effect

Many organizations have a backup system in place, to store and protect data therefore makes the difference between data and information on what reserve?

• Storage is a storage device storing information in the house for a long-term. Data Warehouse protect and save unnecessary history information on a daily basis per day. But an important and necessary for the future, such as data for compliance statutory provisions will remain unchanged. Archive for the indexing. Optimization is to find a file and retrieve information quickly and easily. The technology is generally considered Storage Media Tape drives used. Hard drives and optical. Blu - ray ™ media.
• Backup is a large reservoir to be used to store multiple sets Data. The backup will be used to recover data if they are damaged or destroyed, should be recovered. Usually the backup. If more of the storage and a lower price for the call. In contrast to the backup data is not indexed, or designed for a place and a speedy recovery and a shorter stay. Technology commonly used for backup to tape drives and hard drives.

Two important differences between the backup and storage length data storage and the ability to retrieve data. Not only data stored. But offload content from the holdings of the Central Archives of the short-term safety of long-term Storage. Instead, they collect data for future use and for shared memory. - All at low cost. This ensures that sensitive information remain safe and accessible for decades to restore. His inventory process, storage and recovery improve productivity.

With increasing storage needs of the world.

In the last five years of electronic data must be retained capacity. Currently there are no online outgrown the space in the ability to store data. Information that is stored locally. Or a personal hard drive or tape online remains firm and is not protected.

An important reason for the lack of space is not enough, IT can order with rapid growth sustainability of the data. They have resources. Limited to operate efficiently and cost-saving of the current demand and to manage. Create new skills. As a result, many organizations began, to the memory requirements through the purchase of additional space on the hard disk and add the server. Although effective, these methods tend to clog quickly and lose Square with the online network. In addition, duplicate data will be saved and more often. Eat up storage room that could be better and more efficient. Use.

The growth of electronic data is certainly not a time and space are still scarce. Hence the need for offline storage is more necessary for both. Reasons the cost and efficiency benefits. Data Warehouse can fill the space race was created to help. Companies, the efficiency in the management of the old and the current efficiency to increase and ease of storage. Costs.

Information stored in the gap..

• • inactive and active data managed and maintained in bundle preservation is not working.
• • Keep the information can not be restored or recovered quickly and easily.

Data warehouse to meet demand through to save. .

• • Moving data from online storage to offline storage, the opportunity to create a liberating new information more current.
• • Reduce storage costs with the information system affordable. Logistics and Management Automation.

Fill the earth and compliance requirements of the law.

Thousands of rules on the date of this must be saved and there are too many rules of behavior observed. In place to ensure that the data set that can be reproduced without modification of original be. From the Office of the standard rules. Sarbanes - Oxley, industry all over the world find themselves under very specific mountain. Compliance with strict standards and laws and regulations. In addition, to current practice. Companies face the problem of litigation is often difficult to produce documents and other information. Used as evidence in any court.

It is clear that electronic documents and records an increasingly important role in these contracts. Medical records, e - mail, financial data and pictures are just a few Examples of information that the organization may subject to the laws and rules to remember. As a result, countless professionals around the world. The organization must instead of good architecture to store, to store and manage electronic information, including the ability to produce original. Actual data at random and unpredictable. Time nature of their technologies to gather information that can satisfy this need.

Regulations and laws to require compliance. Companies.

• • Keep important information for a long time.
• • store and manipulate the same record in a first time to be saved and not change it, and people is not allowed the right to deny access to such information.
• • Hold the information so you can easily explore on the pull

Ensure effective data collection to that information.

• • Available for the restoration for years or decades.
• • are safe from unauthorized access. And modifications.
• • You can recall with random access.

III archiving technology. Storage

Three technologies available for the stored information. .

• • The hard disk drives (HDDs).
• • Tape drives.
• • Optical media.

Hard disk drive - success and failure.

Hard drive regularly in online or Near-line storage, with a role in virtually all areas of the digital world as we know it today. People and organizations to large quantities. Details of the various Versions of the hard disk. Playback of MP3, mobile phone, PC Business web applications and enterprise storage systems, an example of a drive that is used all over the world. Hard drives are widely used because it produced with inexpensive magnetic drive that is capable of large-scale is. These skills are used to large amounts of data Availability store. - Hogging, such as records, music and video. Although the hard disk is an effective way to store, they will not collect the complete When it comes to hard drive space, is good news and bad news.

First the good news.

• Using data on the hard disk storage can be accessed quickly. Such as hard drives can be used. Primary or secondary storage of data is retrieved in seconds. • ability to pay. Over the years, driven at the expense of the hard drive near the line so that they buy. With regard to the purchase of high-performance hard drive as in the main memory. • Compliance. Hard drives are basic abilities required to follow the rules and regulations. Verify data in its original format be restored on request.

Now the bad news.

• • Long-term Storage? It is hardly true that hard drives can store basic information to meet their storage needs must. But a regular hard drive specifically intended for children. 35 years for organizations, information, or 1015 years to reproduce the road because of the rules, regulations and laws do no good.
• • Out with the old. Hard drives are not designed for shelves. unpowered hard drives are designed to heat up only when turned on, and they tend to quickly sit when they fail. unpowered on the shelf, the administration is offline, the same information, just not with this form of technology that stored is possible.
• • What goes up forever. Power and air conditioning are significantly high HDD operating costs. In addition, given the short life of their migration to the new hard disk all the necessary throw in 3-5 years time and money spent for reliability and what happens? Expenditure the organization and the environment, especially if they need to.
• • To err error. If the type of hard disk, so people are tend to technology, want to leave something with automatic speed and reliability that is. So what happens when technology fails? When it comes to the business. HDD, this is the most important question. While the hard disk, memory would be ready for them with the two types of errors in reading. : The failure of the operation and latency.

Disk read error.

Hard drive is probably due to errors in reading, including operation or run malicious nature. Both are obstacles to the ability of the hard disk to store data reliably. But the failure to distinguish the two.

Operational failure often occurs when data is not written to disk because the disk itself has ceased to function. Latent failures occur when the hard disk with data written to the hard drive to work. drawn but the error of the electronic media and content protection mechanisms. Error latency is the dominant source of errors on the Hard disk space.

Failure is a very low latency. Complex than the failure of the operation just because there are many factors that make them occur, and these Factors can often lurk. Invisible and unnoticed until it is too late.

Cause of the failure of the hard disk hidden.

Cause latent failure Hard disk is not readable and unstable.

Causes of failure. Latent Including:.

• • Heat-and not even aware Demagnetization. If your hard drive or internal heat. The power consumption of the system hard drive and components produced at room temperature is a bit is stored on the drive not properly, slowly. As a result of thermal decomposition. Stands hard drives. Areas vulnerable to data loss due to decay heat
• • Corrosion: The corrosion of components within the drive can. Including media, automotive parts and assemblies. Severe form of corrosion occurs with the media itself. If a site is on a plate etching the hard drive developed lead to data loss.
• • Infiltration or contaminated dust : It's easier than the sound of air pollution. - Sits on the surface of the disk, often unreadable. This phenomenon can as the location for the corrosion protection or loss of data as possible.
• • Out - Gasification: Out - fumigation usually refers to the introduction of vapor hazards. HDD cartridge internal parts or in the case of hard times. Out - Gasification dangerous to rely on the disk drive that resulted in the loss of territory or a severe reaction. This process eventually lead to loss of data.
• • Adhesive-free: some HDD, such as filtering and higher rank within the single hard disk is installed with adhesive. This adhesive can break due to temperature or humidity, release the filter. On the other hand, it can cause internal to rub or parts in contact with the disc, which will take effect. With regard to information that can not be restored.

To still to make matters worse, research has shown significantly increased latency. The hard drive is in error over time. Hard drive near the line. (The general format of a hard disk Archive). More likely to develop latent errors, as enterprise hard drives in one study, 3.45% of 1,530,000. Development of disk errors and latency. This increase in the twinkling of an eye for the straight lines near the disk. It also drives with errors experienced common mistake to develop in the future.

So the question remains as good as your data if you can not read? Negative impact on the organization of information. Time and as a result of financial problems. HDD is much easier to read.

It all depends on not to storage and hard drives as good outweigh the bad. Due to the increase of electronic data. The increasing need for information in the data warehouse begins to anticipate Industry in a position to have sufficient hard drive capacity. The progress of the digital information on the Internet is increasing the amount of data on personal are stored computer and the server has a demand for higher capacity storage for data created by offline ban HDDs by a powerful tool for archiving. In addition to the failure to read. Cost of higher operating and the inability of the hard disk to store data for long-term significant connections Lack of long-term storage of hard disk technology to less option is more appropriate to archive.

Tape drive - ideal for backing up data is not good for archiving.

Tape drives as storage devices. The magnetic tape for reading and writing data. Band itself is the main package on Tape or cartridge that is inserted into the drive. Drives can be connected to personal computers. Through connections such as cables. SATA, USB or FireWire as many tape drives are often located in large tape autoloaders and libraries. These devices often contain built-in barcode reader. Enter tape automation and loaded into the tape drive. - Interventions of man is not required.

The greatest advantage of tape drives that to store masses of information. Tape drive capacity of a few. MB 100 GB, far beyond the capabilities of the disk storage and storage networking. But benefit. Large one with obstacles. : The rate of access to information, they will slow down significantly. Tapes are usually stored data sequence. (With the ability to random hard drives store data comparison). And access. Data to tape can take anywhere from a few seconds to two or three minutes. Despite many calls and times of their lazy. Tape drives, the transfer of a linear flow rate of large amounts of data. For this reason, once the tape drive, the most commonly used for backup.

Although the ability to store data. Tape drives are not a reliable option. Storage requirements, as they are not designed to read or write individual files. In addition, a basic rewrite Band - A major drawback to the verification of compliance with any and all requirement for compatibility is also not suitable for the tape drive is strong. Standard tapes tend to change every decade. Sometimes, more often than that. This means that almost any tape format is proprietary. And is not compatible to the back. If performance Foreground. Updated drive current standards or to vary at all depending on the technology manufacturers and suppliers mean effective. To solve the problem of Archiving.

Here's good news and bad news about the band archive.

Good news.

• Low cost increases. Most organizations have to secure some form of tape drives for data space, the minimal cost is, if the same drive is used in key locations. In addition, the tape stops and low power consumption, resulting in lower operating costs. • Long-term storage. Old information is removed and stored off-line and the average life expectancy. Range of 7-10 years to tape.

Obituary.

• • incompatible due to changes in technology or tape every decade earlier tape, while this may not able to read or access when it opens technology to get the next. As a result, no additional costs. Out - of - pocket on the needs of the band Hardware and software upgrades.
• • Technology Rewritable. Default. Bands can be substantially rewritten. More technology, so that the tape drive motor to be resistant to change WORM (Write Once Read Many), provides for the decade long life of the tape that the data for a period stored time-critical. However, not long shelf life do not guarantee that the same information is restored unchanged in the future. When it comes to questions of Compliance is to forget everything. Tape will not exist. Opportunities in a court.
• • slow access times. For all intents and Purposes. Data stored on the tape drive is accessible. But as tapes to order for access. The need roll, band. Retrieval was delayed. Finally, is the slow time billing technology is not able to respond and unpredictable.
• • Vulnerability. Even if the old data drive removed and stored off-line. Glue the risk of electromagnetic radiation and require regular maintenance to prevent the tape from sticking. As Result will require the support staff to the tape to the same criteria, state-owned.

Storage Technology is a discussion on the tape drive is almost moot point. Over the years it has been a reliable backup to a tape with little user intervention. In addition to high-speed tape systems and the ability grow. But given the recent development of the Internet. And the current economic time tape backup and recovery is too slow inhibition. By keeping pace with of technology, increased demand for data warehousing and efficient this was also the technology. surpassed by reducing costs and increasing availability heavy storage drive. Long story short. Shoes do not fit.

Optical media - data storage, reliable alternative.

Most people are familiar with the capabilities of high quality. Blu - ray. Save "Video games and other interactive content However, other Forms of optical media, a better choice when it comes to data archiving. Archives optical technology Blu-ray discs in a wide range of information recorded and stored offline on-line or near capacity. While disk storage is a good option for short-term storage. Tape drives effective means to ensure these technologies can not meet the needs of the most important and ongoing needs of the data warehouse. : Safety of long-term data storage and easy. Access to not only media coverage, developed for the needs of today's video industry, it also serves as a robust and reliable data storage solutions and sustainable now and in the future.

The main advantage of optical storage media as well. .

• • Reduce the risk of data loss.
• • Reduce the Costs for storage.
• • Long-term storage stability and compatibility.
• • Low cost, low power consumption and low Carbon dioxide emissions over time.

Reduced the risk of data loss.

Media Blu - ray worm 100%, which means that while the original data stored on the disc can not be changed, it can always be accessed. This is good Messages when it comes to laws and regulations. Standard optical technology provide built-in functions that may not have the information be removed. Amended or approved access without the correct file - was to have when you need it with honesty is not dangerous. Warranty

Reduce storage costs.

Blu - ray the same physical size as standard CD or DVD Factor difference between the three types of optical media is a technology. Blu - ray used a blue-violet laser used, the wavelengths shorter than the standard red laser for CDs and DVDs. This allows Blu - ray standards are up to. 50 GB of data and disc manufacturers, has announced plans for construction. 100 GB disc in the near future.

In addition, Blu-ray technology has created the opportunity model. multi-layer/extended. This means that the capacity requirements. A piece of Blu-ray media. In the not too distant future -,. 4 - Layer Blu - ray capacity is up to. 200 GB of data.

Long-term storage stability and compatibility.

The average life span of Blu - ray dual-layer 50GB disc is of 20 to 100 years. Two physical factors that lead to. Superiority and reliability of optical media.

First, Blu - ray-protected hard coating on the outer Surface scratches and fingerprints, no problem. In addition to supporting the worm, the data is stored on the disc is not n of the department or Umeeongpri ใ outside, damage can be guaranteed. Coating Blu - ray advanced to prevent the disc itself from physical damage. This function will generate the kind of protection. Double blow to the privacy of the dangers of most

Second, the optical media will be created in industry standard format. : ISO 9660 and UDF Both go backward compatibility. These formats are supported on all major operating systems. : Windows, Linux, UNIX and Mac OS in other words, the optical Media very confident that both this and next year. Blu - ray can be used to benefit and standard computer can be read. (More evidence: a CD from front 25 years will be read today. The PC standard). No need to worry about ownership issues related to the optical drive. - Tape is not about the technology standards and to grow, it does not. And vice versa. Long life and high compatibility with the standard of the Blu - ray media that the original data from memory and file can be found on the hard drive to access any guarantees. Time without the need for resources to improve the software and technology.

Low Cost, low power consumption and low carbon dioxide emissions over time.

Over time, Blu - ray energy efficient than hard disk drives. Blu - ray cost of ownership will be lower because.

• ray can store a lot - • Blu. Information and technology that allows more natural level and the content will be added to the price.
• • Media Blu - ray long-term storage of the storage solution.
• • Blu - ray capabilities and to support broad-based platform that the need to migrate to new technologies eliminated.

The interest cost of the optical. Finally, the media interpreted as a benefit for the environment. Optical storage technology is a low power consumption needs of other data storage today. Prerequisites: organic Sustainability. This is the reason.

• • Optical media storage devices. passive, no energy in the last decades of storage. - IT does not use power if they are not used to access data and information.
• • Energy is needed to operate and use the media. Blu - ray is very low, because the use of shared resources.
• • Media Blu - ray a significantly smaller number of heat that is less energy is not used in the cooling capacity, means.

When it comes to data storage, optical media is an option that is efficient and reliable. Blu - ray formatted specifically for the needs of industry wide on video. - A clear advantage. As hard drives and tape drives. Second, the optical storage technology is reliable. Long life is, and Available remotely. Also ensure a lower cost of the optical media. Storage of corporate data leaves a small footprint and more Money in the bank.

As a result of the strong character of the optical media, the support increased. Meet the requirements of laws and regulations. This Related requirements.

• • Long-term storage.
• • Reproduction not change the original recording.
• • Quality the storage architecture in place for compliance and

IV conclusions.

In to infiltrate our digital world of electronic information industry and dominate global business. Because of our global economy continues for more details. - Based masses of electronic data for the purpose of continuing this growth and that will not slow down. As a result, global demand for increased data storage to handle increased saving requirements in professional bodies to ensure that the technology to store data in a safe place and to protect electronic data. Inventory data not luxurious, it is a necessity in the current rapid social

Current technology has the storage capacity of disk and tape media. Blu - ray optical question is: how the archive. Technology for reliable financial and organizational advantages in a package or not. The answer is the optical media.

Hard impact at short notice. But tend to be. The failure of the operation and latency of this technology proved to be unreliable and data storage equipment is not safe. Tape Drive is so effective in the industry for data backup. But to their high. Therefore, the technique can not do remain the key for efficient data archiving options. Disk and tape drive technology does not meet the needs of the most important. : The long-term archiving Blu - ray durable. Formatted specifically for the media industry and popular when old. Optical media 2-10 years for all archived data, while also responding to the cost and efficiency. Needs that go beyond the capabilities of the two hard disk ribbon
