Good question. The TSM manuals leave that unexplained. The redbook
"Implementing IBM Tape in Unix Systems" provides some insight...
"Because Tivoli Storage Manager can distinguish between WORM and R/W
cartridges (assigns “media type” of 412 for WORM cartridges and 411
for R/W cartridges at the time of check-in), you can have both WORM
and R/W cartridges in a single logical library just by defining
device classes, one with WORM=yes and the other with WORM=no."
There are some things which TSM knows "under the covers". Media type
is revealed in the output of the Query LIBVolume command.
