Why the tape media is mostly used for back up purposes?

Tape drives are a form of digital storage devices which use tape for information recording. Because of the cost effective nature of the tape material and their long archival life, tape drives are widely used for backup and archival purposes. A tape drive cannot be accessed randomly like with the hard drives to read a particular piece of data. However, the tape drives can stream data very fast once they are positioned to the particular data point. Because of this factor, tape drives cannot be used for daily storage purposes. There are many formats available for storage of digital information on tape drives. Some of the popular ones are DDS (Digital Data Storage), AIT (Advanced intelligent tape) introduced by Sony and many others. These formats have several generations. AIT is a high speed format for data storage on tapes.
The raw data capacity of tape drives is fixed. However, more amounts of data can be stored on them by using compression. Most of the tape drives have a compression ratio of 2:1. Some tape drives when used with only certain data types can achieve a compression of about 10:1 also. Tape drives can be connected to the computer by using a SCSI interface or other common types as firewire and usb. The reliability according to the recently conducted surveys is not good. Most companies do not test or try to recover from tape archives and some companies that do experienced 77 % failure in achieving a backup of stored data. So, many of the companies in 2011 are starting to move from a tape based back-up solution to a disk based solution.
A large collection of tapes in a huge structure with a mechanical tape loading device is called a tape library. Tape libraries are used for heavy data archival needs like that of financial records of a company. These data facilities take up a lot of money to setup and maintain. A tape library is a digital archive that can store huge amounts of data ranging from several TB to few PetaByte or few 1000 TBs. A trade off exists for higher storage capacities. The access time becomes slower because of mechanical parts and machines when the storage amount increases. Tape autoloaders are tape library devices with a single drive. There are several software technologies for operation of tape libraries. Some of them include open source tape library softwares like AMANDA, Bacula, and the minimal mtx program.

What is a tape autoloader and How to manually unlock magazine from HP tape autoloader?

An autoloader is a data storage device that uses tape for storage of digital information. An autoloader is basically a tape library with a single drive. It is mainly used for data back-up purposes. A tape library is a huge collection of tapes operated by a mechanical device to load the required tape in to the drive for access. Usually, tape drives are implemented in stages of digital archiving. For example, the requirement of data archiving of a company’s customer information. Tape libraries can range from a single drive autoloaders to multi-storey huge capacity data storage facility operated by robotic arms for mechanical loading. Such facilities have high costs and are for professional purposes. Tape Autoloader is a general purpose tape library as it has only a single drive.
Tape Autoloaders are cost-effective and easy-to-install devices which provide unattended backup. These devices are ideal for an entry-level or remote office automated backup solution. Tape autoloaders generally have a form factor of few rack units for their incorporation in to rack shelves. They provide huge data storage capacities of about several TBs. Some of these Tape autoloaders can be operated remotely via internet. So, one can configure, monitor or troubleshoot the device remotely. This will reduce dependency on the local staff and local operators. Some good tape autoloaders also provide encryption facility to encrypt your secret and confidential data so that if the tape drive is stolen or lost, then your information will be protected. They also provide softwares which continuously optimize and monitor the operational performance of the tape autoloader.
HP tape autoloaders have good features in a price effective fashion. If in a HP tape autoloader or any other tape autoloader, the tape is struck in the storage module, it is necessary to remove the tape and the magazine from the autoloader manually. Firstly, to do this, we need to move the tapes in to the magazine using Move Tape command. Then, use the magazine removal process of the autoloader device to remove the magazine from it. If this is not possible, then we can try to manually remove the magazine from device by inserting a finger in the hole at the back of the magazine. Some tapes need to be inserted and removed several times to condition them for free movement in and out of the magazine.

Junk Garbage (DK) Tractor Feed Assemblies

In operation of the specific embodiment employing the present invention and with the modular bidirectional tractor feed assembly 10 installed on a suitable printer, the operator will adjust the positions of tractor mechanisms 34 and 36 to the width position to accommodate the particular width of record material 54 to be used for the printing operation. Graduated scale 56 provides guide lines, which the operator may use to determine the positions desired to place the tractor mechanisms 34 and36. In order to relocate the tractor mechanisms 34 and 36, the operator will release the tractor mechanisms 34 and 36 from notched rail member 30 by operation of lever 66 and the corresponding lever on tractor mechanism 36, move them to the new location and lock them in place on notched rail member 30 by operation of the same levers. With the assistance of paper edge guide 72 on tractor mechanism 34 and the corresponding paper edge guide on tractor mechanism 36, the operator will insert the leading edge of the record material 54 onto the notched rail member 30, the platform 74 of tractor mechanism 34 and the corresponding platform of tractor mechanism 36. The operator will then initiate paper feed to the printer, which will apply a rotational force to gears 24 and 28 through the connection to the printer. Splined shaft 26 and shaft 20 will rotate resulting in the rotation of platen 18 and chain 106 in tractor mechanism 34 together with the corresponding chain in tractor mechanism 36. As the operator further inserts the record material 54, filling slots 76 and 76a and the corresponding filling slots of tractor mechanism 36 provide assist in positioning the perforations 70 over the offset pins 68 for positive and accurate feeding through tractor mechanisms 34 and 36, between the paper pan 12 and bar 48 together with platen 18. After a sufficient portion of record material 54 has been fed, the operation will stop the paper feed and lift guide plate 78 and the corresponding guide plate of tractor mechanism 36 and place the record material 54 around platen 18 and onto the offset pins 68. The perforations 70 of the record material 54 will align because of the factory adjustment of the position of splined shaft 26 relative to shaft 20 of platen 18. The record material will also be properly tensioned. The operator will then lower guide plate 78 and the corresponding guide plate of tractor mechanism 36, and the system will be ready for a printing operation. The presence of record material 54 will be sensed by the paper-out sensing means, and an indication will be sent to the printer that printing may be initiated. As printing continues, gearing (not shown) in the host printer (not shown) will rotate gears 24 and 28, which will result in rotation of platen 18 and tractor mechanisms 34 and 36 and the feeding of the record material 54. The tractor feed assembly 10 will feed the record material 54 in either direction as dictated by the direction of rotation of gears 24 and 28.
