Sony Advanced Intelligent Tape (AIT)Sony Advanced Intelligent Tape (AIT) technology has been a leader in back-up tape for a number of years. AIT uses a 8mm tape, 3.5 inch drive form-factor and a drive mechanism that utilizes helical-scan recording, unique Memory-in-Cassette (MIC) architecture (R-MIC is a non-volatile chip built into the data cartridge that provides quick media loads and allows fast searches to data. The R-MIC chip contains the tape's system log, search map and user-definable information, allowing the drive to advance at a high speed directly to any file on the tape), advanced read/write head technology and the exclusive use of Advanced Metal Evaporated (AME) media. These characteristics result in high capacity and performance, outstanding reliability, fast data search and superior data protection through the use of Write-Once-Read-Many (WORM) capability. Sony AIT backup tape drives are also designed for backwards compatibility (AIT-5 compatible with AIT-4 AIT-3EX, AIT-3. AIT-4 compatible with AIT-3EX. AIT-3EX compatible with AIT-3 and AIT Turbo Series E, 1 and 2). Benefits include: Enables WORM protected backup on tape, which is ideal for - compliance storage, enables encryption for compliance related, greater tape head durability,Shoe-shining is minimize compared to linear tape formats, one pass to fill the tape cartridge contributes to reliable operation and exceptional reliability enabled by minimizing tape tension, compared to Linear Tape formats.
