Advanced Intelligent Tape (AIT) was introduced by Sony in 1996, and was a magnetic tape format for data storage.
AIT uses a cassette with 8mm tape similar to Sony’s Video8, and uses helical scan technology and a memory chip that keeps relevant information about the tape.
Five generations of AIT were released, and unlike other tape data formats, each was backwards and forwards compatable with multiple generations. AIT-1 was released in 1996 with a capacity of 20 GB, and AIT-5 was released in 2007, with a capacity of 400 GB.
It was discontinued in 2010.
