A program schedule with milestones is given for the materials development and recorder construction for an optical disc recorder. This schedule will be used, updated where necessary, on all subsequent reports. The recorder components were fabricated, and the recorder is being assembled. Laser machining of bismuth and selenium films produced at PL indicates acceptable sensitivity and hole geometries. The air sandwich appears to be the most attractive protective mechanism for the disc and has been chosen as the prime candidate for extensive testing and analysis. A task force was set up to study digital coding problems.
