TS11xx Technology Read/Write Compatibility
The following table shows the media read/write compatibility for each
TS11xx technology drive generation supported by the library.
WORM Media
Certain records retention and data security applications require a Write
Once, Read Many (WORM) method for storing data on tape. LTO‐4 and
later generation drives and TS11xx technology drives enable WORM
support when a WORM tape cartridge is loaded into the drive.
WORM Media Requirements Because standard read/write media are
incompatible with the WORM feature, a specially formatted WORM tape
cartridge is required. Each WORM cartridge has a unique, worldwide
cartridge identifier (WWCID), which comprises the unique CM chip serial
number and the unique tape media serial number.
Data Security on WORM Media Certain built‐in security measures help
ensure that the data written on a WORM cartridge does not become
compromised, for example:
 The format of a WORM tape cartridge is unlike that of standard read/
 When the drive senses a WORM cartridge, the firmware prohibits the
