The recorder was modified for limited operation at 3 rps. Refitting the new optical and digital subsystems into a deliverable system is now planned on a back-up sled and turntable. PMMA discs coated with tellurium films were recorded on through the backside of the disc surface. Air sandwich fabrication is showing good progress. First results of an accelerated life testing program indicate that tellurium films do not degrade at high temperatures. An initial recommendation for digital formatting, coding, and error correction techniques is given. A theoretical analysis of expected hole machining characteristics for a moving substrate was performed.
