You can manage your optical drives more efficiently by grouping them and defining optical libraries using ISMF. These definitions are used with other SMS constructs, ACS routines, and the object access method (OAM) to manage the object data. You can then use automated optical libraries with pseudo optical libraries to more efficiently manage the placement and migration of your object data.

With OAM, rewritable optical disks in automated optical libraries can be automatically reused when all the data has expired. When all the data expires on optical disks that are not rewritable, the disks can be removed from the automated optical library. For more information, see Objects.
