Increased Media Durability Of Sony AIT Tape

Most essential fundamental attributes for archival applications are high capacity, durability, lower cost, robustness and retention of data for longer time period. Large organization’s branch offices and the SMB segment require cost efficient, high speed and tough tape technologies for fulfilling their specific needs of data archiving and protection. These archiving applications usually require modest input/output transfer rates.

Helical scan technique was engineered by Sony Corporation and is incorporated in AIT technology. Helical scan has the potential to further enhance and increase the density in comparison to linear technique. Helical scan is sometimes also called “linear serpentine”. The tape technologies differ from each other by the technique used for storing information. Helical scan is very adaptable and has space efficient features. It can be easily used in variety of different recording applications. Helical scan provides reliable packing density with reduced power consumption and tape tension.

On the other hand, the linear technologies consume more energy as the mechanism design of stationary assembly head is much larger. Helical scan can record the entire tape media content in a single pass. While in linear recording, the tape is moved back and forth so that the information could be recorded onto the media. Helical scan process reduces tape tension and increase media’s durability. AME formulation results in smoother surface of AIT tape.

The cartridge size of those data tapes is large that use the linear technology, because to achieve larger capacities, large media quantity is required by them. AIT-5 is the latest member of the Sony AIT family that can store massive 400 GB uncompressed information. Helical scan provides high capacity storage solutions for SMBs and enterprises. Sony Corporation has extended the capability of AIT tape format by introducing the AIT-5 technology that is high density and space efficient data backup solution. Sony AIT5 tape is the first format that whose native capacity reaches 400 GB in small 3.5˝ form factor.

Data bits in tape media’s particular area is the recording density. Recording density is the fundamental driver for greater storage capacity both in data tapes and disk drives. In comparison to the linear tape methods, the helical-scan technology helps the AIT tape format to record four times more tracks per inch. This results in recorded density that is 4 times more than that of linear technology. Linear technologies need more tape amount so their cartridge and drive’s size also increases. Therefore they will consume more power and space.

Sony AIT tape solutions provide remarkable backup features that consume lesser power with higher output level. Helical scan process reduces tape tension and increase media’s durability. AME formulation results in smoother surface of AIT tape. Multiple tape passes in linear mechanism increases stress and pressure on media. Therefore this can affect the data storage in long term. Smaller factor of AIT tape format provides increased application stability with lower floor space for storing tape cartridges.
