Sony AIT1 SDX-400c

Sony AIT1 AIT Tape Drive

The Sony SDX-400C drive uses data compression to achieve high capacity and high transfer rates. Actual capacity and transfer rate depends on the source file type.

The capacity ratings listed in the next subsection are based on a 170 meter tape AIT-1 cassette (SDX-T3N and SDX-T3C) and 230 meter tape AIT-1 cassette (SDX1-35C). The Sony SDX-400C drive is a high capacity data storage device using Advanced intelligent tape (AIT) technology. The Sony SDX-400C drive achieves high data integrity through read-after-write, an additional level of Error Correction Code, and other features.

The Sony SDX-400C drives provide MIC technology that automatically enhance reliability and performance. The Sony SDX-400C drives provide read and write capability for MIC user data area.
