Real-time Staging on Optical Disk Library

Abstract

In an optical library system [1], since the disks that have recently been used are often likely to be used again shortly thereafter, the presence of disks stored near the disk drive increases the overall speed of the system (Fig. 1). The movement of disks from a relatively far cell to a relatively close cell is known as "staging". In real-time staging, the disks are staged through the conventional read/write process between the storage cells and the disk drive to permit rapid access to the disks as required in the future.
