Advanced Intelligent Tape
Advanced Intelligent Tape (AIT ) is a magnetic tape system for storing data. It was introduced in 1996 and is a development of the Digital Audio Tape (DAT ) from Sony, the metal-coated tapes Advanced Metal Evaporated ( AME ) was used and compared to a DAT about four times higher storage capacity allows. AIT technology is - used exclusively in the area of data backup - in contrast to DAT. The production and distribution of AIT technology ceased in 2010.
Technology
The magnetic tape system is composed of an 8-mm helical scan technology, and used as an index, the MIC (memory in cassette) and for compressing the ALDC (Advanced Lossless Data Compression ). The compression rate is approx 2.6 to 1
