  • Method for deleting objects from library resident optical disks by accumulating pending delete requests
    Patent number: 5325523
    Abstract: The response time of an automated optical disk library is improved by writing object delete requests to a deleted objects table before actually physically deleting those objects. By collecting object delete requests in a list of pending deletes for each volume in the library the number of necessary mounts are reduced. The delete requests in a list of pending deletes for a given volume are physically deleted just prior to performing a write or defrag request for that volume. The list of pending deletes for that volume are then deleted from the deleted objects table. During idle periods a predetermined number of pending delete requests will be performed for the currently mounted volume. If there are no pending delete requests for the currently mounted volume then a predetermined number of pending delete requests will be performed on the opposite side of the currently mounted volume.
