AIT-5 Media uses the new AME III coating. This technology improves upon its predecessor, AME II, with a new method for applying the magnetic layer to the tape, an enforced coating layer and a newly developed lubricant for stable operation. AME III media realizes high output and low noise through an improved metal evaporated method, resulting in smaller magnetic particles and a smoother tape that minimizes the spacing loss between the magnetic head and the magnetic layer.

Advanced Intelligent Tape
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 base film 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.
