VolSafe Cartridges
VolSafe (volume safe) and WORM-enabled tape drives provides write once, read many
(WORM) technology to VolSafe designated cartridges. VolSafe permits new data to only
append the tape media, while it prevents erasure or overwrite of previously written
data.
All StorageTek T-Series tape drives are VolSafe-technology-capable and you can identify
the VolSafe cartridge by the colored areas on the cartridge.
