Advanced Intelligent Tape is a Sony format for helical scan storage of data on
8mm tape cartridges.
The cartridges themselves are sophisticated, using AME formulations based
on cobalt and featuring electronically readable memory on the cartridges known
as MIC or "Memory-In-Cassette". This allows most drive/software
combinations to identify the cartridge and it's contents independently of user
error or action. In addition, AIT drives are self cleaning under most
circumstances and can warn the user when a cartridge is developing errors or
wearing out.
This format is not compatible with other common 8mm tape formulations and
storage layouts.
