摘要： An embodiment of the invention comprises a virtual tape system supporting at least one Write Once Read Many (WORM) logical tape and at least one read-write logical tape, comprising a processor configured to a first task and/or a second task. The first task initializes a new logical data object from a single pool of at least two logical data objects, with the new logical data object bound with a member of a media type group consisting of a WORM data object or a read-write data object. The second task reuses one of the logical data objects without manual ejection and reinsertion. The reuse may include the processor configured to cycle the logical data object through a scratch pool as a selected scratch logical data object and mount the selected scratch logical data object with a write from beginning of tape command to bind at least one data attribute to the WORM data object.
