Advanced Intelligent Tape ( AIT ) is a magnetic tape system for data storage . It was introduced in 1996 and is a further development of Sony Digital Audio Tape (DAT) , which uses metal-coated tapes ( Advanced Metal Evaporated , AME) and enables a storage capacity that is about four times higher than that of DAT . In contrast to DAT, AIT technology is used exclusively in the area of data backup . The production and sale of AIT technology was discontinued in 2010.
technology
The magnetic tape system consists of an 8 mm helical scan and uses the MIC ( Memory-in-Cassette ) index technology and the ALDC ( Advanced Lossless Data Compression ) method for compression . The compression rate is around 2.6 to 1.
