AIT 2 Tapes

By: Shawn

AIT-2 (Advanced Intelligent Tape) tape media is a formatcontrolled by Sony. Typical AIT-2 tapecartridges have a 50 GB native and 130 GB compressed capacity. Thecompression ratio assumed for AIT products is 2.6:1 which is theoreticallypossible but is only likely to occur for tect documents, etc because other filetypes such as pictures etc do not compress very well.

Similarly transfer rates for AIT-2 tapes in general rangefrom 6 MB/s native up to 12 MB/s compressed. AIT-2 tapes have double thecapacity and double the transfer rates as well. As AIT tapes use a differentencoding mechanism, therefore they have a better compression ratio (2.6:1).

Some other important facts about AIT-2tapes are that the WORM (Write Once Read Many) cartridge in the AITline was first introduced in AIT-2 tapes. Turbo variants of AIT-2 tapes werealso launched that have 80 GB native capacities (and 208 GB compressed) and 12MB/s native transfer rates. One of the most commendable features in the AIT-2Turbo variant is the R-MIC (Remote - Memory In Cassette) chip that helps speedup data access. As they say time is money and anything that saves timetherefore saves money and who wouldn't want that?

While a lot of information is available regarding AIT-2tapes throughout the Web, some sites are available that have a lot ofinformation regarding SonyAIT tape media. One such is Tape4Backup and while it is not aspecialist site for AIT-2 tapes, it does have a lot of information regardingthe more important aspects of AIT-2 tapes.

That's all for now although be on the lookout for morearticles regarding other tape cartridges.
