Advanced Intelligent Tape

Super AIT (SAIT) is a higher capacity variant using wider half inch (1/2") tape in a larger, single-spool cartridge.

Both AIT and SAIT use the helical scan method of reading and writing to the tape.

In March 2010, Sony announced the discontinuation of the AIT product line, and renewed collaboration with Hewlett-Packard on further development of the DDS tape format,[1] One of the most compelling features of the AIT format is that many generations are both backwards and forwards compatible.

Released in 2006 by Sony, available only in libraries, 800 GB native and 45 MB/s sustained transfer rate.

Memory-in-Cassette is a 16-64KB memory chip in the cartridge that keeps relevant information about the data on the tape to allow quicker access.
