Data security on WORM media

Certain built-in security measures help ensure that the data that is written on a WORM cartridge does not become compromised.

For example:
  • The format of an Ultrium WORM Tape Cartridge is not the same as the standard read/write media. This unique format prevents a drive that lacks WORM-capable firmware from writing on a WORM tape cartridge. For LTO 9, native data capacity is 18 TB and compressed data capacity is 45 TB.
  • When the drive senses a WORM cartridge, the firmware prohibits the changing or altering of user data that is already written on the tape. The firmware notes the last point on the tape that can be appended.
