AITi260 Tape Drive The Sony AITi260 drive is a high capacity data storage device using Advanced Intelligent tape (AIT) technology. The AITi260 drive achieves high data reliability through Read-After-Write, an additional level of Error Correction Code, and other features. The Sony AITi260 drive stores data on tape using a standard format called AIT (Advanced Intelligent Tape) and ALDC formats. 3

Precautions Installation Avoid placing the drive in a location subject to: – high humidity – high temperature – mechanical shock and vibration – direct sunlight Operation • Do not move the drive while it is operating. It may cause malfunction. • Avoid exposing the drive to sudden changes from a low to high in temperature. This may cause water condensation to collect inside the drive. If the ambient temperature should suddenly rise while the drive is turned on , wait at least one hour before t

Drive Operation Loading a Cassette Insert a cassette into the slot on the front panel with the arrow on the cassette pointing towards the drive. As the cassette is inserted, the drive takes it and automatically loads it into drive mechanism. Unloading a Cassette The cassette can be removed from the AITi260 either in response to a SCSI Unload Command, or by pressing the eject bottom. By pressing Eject button, the tape goes to BOT, the drive unthreads it, and ejects the cassette from the slot. Wr
