Advanced Intelligent Tape (AIT) is a discontinued high-speed, high-capacity magnetic tape data storage format developed and controlled by Sony. It was introduced in 1996 to utilise Advanced Metal Evaporated (AME) technology. It competed mainly against the DLT, LTO, DAT/DDS, and VXA formats. AIT uses 8mm tape in a cassette similar to Video8. 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.
