Abstract

Access mechanism wear on magnetic disk storage drives is a problem in computer systems, especially in those computer systems having multi-tasking or swapping of main storage tasks. The optical disk storage device 50 in Fig. 1 interfaces with main storage 10, and the more frequent data transfers occur between it and main storage 10 and less frequent data transfers take place between optical disk storage device 50 and fixed file 100.
