From the Manufacturer
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). The SDX3-100C features 100GB native, and 260GB compressed capacity. AIT-3 is scalable and backward compatible with previous generations.
