Abstract

A method of and apparatus for extending the memory capacity of a computer system having a rotating optical memory storage device and a fixed memory storage includes a scanner for accessing computer information and a rotating optical read-write memory device for storing computer information and for accessing and transferring computer information to and from the scanner and to and from the discrete memory storage of the computer system. The method includes the steps of storing computer information on a scannable storage medium, accessing computer information from the scannable storage medium, and transferring the computer information to the scannable storage medium or discrete memory storage of the computer system through the use of a multi-head rotating optical memory device. The scanner uses an optical laser scanning system to encode computer information on a physical medium. The rotating optical memory device uses virtual memory techniques to store and retrieve data for use at a required time.
