WORM Function
The AITi520, AITi260 and AITi130 support the WORM function. This
section 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 AITi520,
AITi260 and AITi130 support 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.
