WORM Function
The AITi200 supports the WORM function. This explains the WORM
function.
What is “WORM”?
“WORM” is an acronym for “Write Once Read Many”, a function that
allows data to be written to the same place on a tape only once, but permits
that data to be read from the tape for any number of times. The AITi200
supports WORM cartridges. When a WORM cartridge is used with an
application that supports the WORM function, data that has been written to
a tape can not be accidentally deleted or overwritten.
A WORM drive operates in the same manner as a non-WORM drive when
used with a non-WORM cartridge (henceforth referred to as “regular
cartridge”).
The operation of a WORM drive and a non-WORM drive differs according
to the type of cartridge that is being used.

WORM Cartridges
WORM cartridges can be distinguished from regular cartridges by their
WORM logo and red shutters.
