Part 3. Operation
WORM Function
The SDX-D550V 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 SDX-D550V 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.
