Abstract

The objective of this MS Thesis is to determine the feasibility of a digital focusing controller for an optical disk tester. Current research in optical data storage requires the use of optical disk testers to charactertize new optical disks in the early prototype stage. The optical disk tester at the Optical Science Laboratory currently uses an analog controller to control the focusing and tracking operations. A digital control system could be used in this tester to greatly improve the performance of the tester. This thesis describes the design of a digital servo control system to control the focusing of the laser beam produced by the optical disk tester.
