Abstract: The design of the signal system of the Electronic Still Store (ESS) graphic retrieval system is discussed. This device can access randomly any one out of thousands of stills in less than 0.1 s and display it indefinitely without deterioration of quality. Further, it can copy stored stills through many generations without loss of quality. Based on the Ampex DM 331 disc file and related computer technology, the ESS-1 uses a removable and interchangeable disc pack. A key factor in achieving a necessary increase in linear recording density without substantially increasing the original DM 331 error rate was the development within Ampex of a new channel-encoding scheme designated M2, for modified-Miller. The M2 code is dc-free and self-clocking. Where a previous paper on the ESS discussed the ESS and its capabilities in a general way, this paper covers signal encoding and decoding, the disc file write-and-read channel, the signal-processing and playback bays, and the means of accomplishing time-base correction.
