Sony AIT (Advanced Intelligent Tape) format is intelligently engineered to stand apart - no other tape cartridge features both an MIC chip (the brains) and a pure metal magnetic layer designed for maximum capacity and longevity (the brawn). AME (Advanced Metal Evaporated) Tape- Now Sony delivers 100% pure cobalt for high retentivity. Patented process for depositing a pure metal magnetic layer directly on the basefilm without adhesive or binders. The benefit from this AME technology is maximum recording performance. MIC (Memory in Cassette)- The AIT cartridges feature a built-in flash memory chip that stores directory and operational information. The result is rapid access to desired data and greatly reduced loading and ejection times. DLC (Diamond Like Carbon) Coating- The tape surface is protected by a smooth carbon coating that is nearly as hard as diamond and 20 times harder than metal oxides. The benefit is maximum reliability and life.
