Development of an Optical Disc Recorder

Abstract

First testing of the recorder is underway. Some tracks were recorded on plastic discs coated with tellurium films. Laser machining of holes in static films of various materials reveals tellurium as an attractive DRAW candidate. The principle advantages of tellurium film (compared to bismuth) are improved sensitivity and stability at high temperature. Detailed analysis of the air- sandwich protective mechanism continues. The first results of the digital coding task force study are being analyzed. A study of accelerated life testing of bismuth and tellurium film was initiated.
