A Real-Time Digital Processor for Disk Mastering Lathe Control

The availability of highly reliable LSI circuitry has made possible a major breakthrough in disk recording lathe control technology. A new system for optimizing the groove-to-land ratio is described which utilizes real-time two-dimensional relationships derived from the audio waveform. This system, based on 12 years' experience with analog designs, achieves a significant advance in the time/level/skill relationships of the phonograph disk when compared to all previous cutting equipment.
