Unylogix UNA-260 Drive Specifications

(Based on the Sony AIT-3 drive)
ATI-3 Drive
Model Overview

AIT-3 drive, available as internal or external with Wide Ultra SCSI SE / LVD Interface

Model Highlights

  • 260 GB capacity and 12.0 MB/s sustained data transfer rate (with 2.6:1 compression)
  • Backward compatibility with AIT-1 and AIT-2 data cartridges
  • Fast media loading (Less than 10 s) and file access (27 s to 37 s)
  • High reliability with MTBF of 300,000 POH (100% duty cycle), head life of 50,000 hours, and media uses of 30,000 end-to-end passes
  • Efficient data management with Memory In Cassette (MIC)
  • Compact 3.5-inch form factor for easy integration into existing systems
  • Active Head Cleaner mechanism and AME media reduce the need for periodic cleaning


    High capacity, high performance
    Sony AIT-3 tape drives deliver up to 260 GB capacity (with 2.6:1 compression) in a compact, 8mm data cartridge. Helical scan technology increases data recording density, while offering fast data transfer rates of up to 28.0 MB/s (2.6:1 compression)

    Fast access to data with MIC
    The unique Memory-In-Cassette feature of Sony AIT drives, with 64 kB of built-in programmable memory, speeds access to data, providing fast loading (less than 10 seconds) and quick file access (27 to 37 seconds).

    High reliability
    Sony AIT tape drives incorporate a redesigned head geometry, reducing head/tape pressure and delivering up to 50,000 hours of head life. The built-in Active Head Cleaner mechanism results in an industry leading MTBF rating of 300,000 POH (100% duty cycle).

    Backward Compatibility
    Sony AIT-3 tape drives are fully read and write backward compatible with both AIT-2 media, 36 GB and 50 GB data cartridges, and AIT-1 media, 25 GB and 35 GB data cartridges. Backward compatibility helps protect your investment in the valuable data you already have stored on AIT-2 and AIT-1 data cartridges, while delivering the increased capacity and performance of AIT-3 technology.

    Reduced periodic maintenance
    Sony AIT drives incorporate an Active Head Cleaner mechanism activated automatically by the drive mechanism when tape errors approach a certain threshold.
