Development of an Optical Disc Recorder
Abstract
The mechanical parts of the recorder were designed and are in the first stages of assembly. The servo electronics were designed and fabricated. A coding study is under way for the design of the record/playback signal processing electronics. An optical system using HeNe lasers for recording and playback has been proposed; a report on this system is given in Appendix A. A study of possible materials for the disc substrate shows that plexiglas (PMMA) would be a good choice. Several mechanisms have been considered for protecting the recording from dust, fingerprints, and scratches. A program for investigating suitable DRAW recording materials has begun.
