Sony SDX135C//AWW AIT1 backup media 35/90GB 1 pack

Sony AIT1 Tape Cartridge

This Sony SDX135C//AWW cartridge provides 35GB native capacity and 90GB compressed capacity for AIT1 tape drives. It is suited for small-business servers or workstations that perform scheduled backups to a single tape library slot. The Memory In Cassette chip stores directory data for faster file location. Supplied as a single sealed cartridge.

Installation and common issues

Insert the cartridge into a compatible AIT1 drive until it clicks; the drive handles threading automatically. Most problems occur when the write-protect tab is left in the locked position or when the tape path is contaminated by dust. Clean the drive heads with an approved cleaning cartridge before important jobs. Verify that the backup software recognises the MIC data after the first load.

Pre-order checks

Confirm the target drive is an AIT1 mechanism — later AIT generations do not read this format. Ensure the backup application supports 35GB native or 90GB compressed capacity without spanning multiple tapes. Check that the library or autoloader accepts standard single-slot AIT1 cartridges. Verify available drive firmware supports the MIC feature for optimal performance.
