A data storage library subsystem and a method for storing, and maintaining and tracking synchronism between, multiple copies of identifiable data volumes between hosts and a plurality of data storage libraries, and transparent to the hosts. The library controller of each library provides an updatable synchronization token directly associated with each data volume. A plurality of directors are provided, each separate from and coupled to the hosts and each separate from and coupled to each data storage library. Each director responds to ones of separate, partitioned access addresses addressed by the hosts. The responding director supplies each data volume supplied from a host to all of the data storage libraries, and updates each synchronization token directly associated with the supplied data volume. Thus, the directors store duplicate copies of the data volume in the data storage libraries without involvement by the host. The currency of the data volumes are each tracked by means of the directly associated synchronization token, and the synchronization token is not tracked by the host nor is a central tracking database required.

A cartridge loading apparatus has at least one movable member with a pin to engage a notch of a cartridge and has a reversible motor. A compliant link has a longitudinal leaf spring resilient beam, and has a laterally extending arm at one end of the beam, forming an “L” shape. The movable member and the motor apparatus are coupled at axes respectively at the other end of the beam and at an end of the arm. Thus, a compression force provides a rotational torque at the arm which flexes the beam outwardly away from a straight line between the axes; and a tension force provides a rotational torque to flex the beam inwardly.

Fast formatting of DASD emulating sectors on optical media is provided to reduce initialization time. Rather than format each track media when a new surface of an optical media is mounted in an optical storage library, a table is created on the media containing a set of entries for each track on the media surface. During initialization, a first table entry for each track is set to indicate that the state of the track is reliably KNOWN and a second entry is set to indicate that the track is virgin (unrecorded). Prior to a subsequent data access operation, the track table is copied from the media into a corresponding table in memory and each first entry in the media table is changed to indicate an UNKNOWN state. The memory track table is updated during the data access operations to reflect newly recorded or updated sectors. Upon completion of the data access, the media table is overwritten with the updated memory table.

A computer installation is programmed for storing data in a magnetic disk DASD (direct access storage device) in the form of a track number identified by DASD cylinder number (CC) and DASD head number (HH). A re-writable, multi-disk optical storage which stores information in a fixed-block architecture including a sequence of sectors having the form of spirals on optical disk surfaces is enabled to emulate magnetic DASD by calculation-based conversion of storage references to magnetic DASD tracks to fixed-block optical sectors.
