Abstract
1392203 Recording and playback RCA CORPORATION 21 March 1972 [22 March 1971] 48664/74 Divided out of 1392202 Heading G5R Signals, e.g. video signals, to be recorded control the switching between zero intensity and a non-zero intensity of an electron beam, e.g. in a scanning electron microscope, which scans a spiral groove in the surface of a disc, the groove having been coated with a photoresist material which is developed after the exposure of the electron beam, producing a disc record in which the bottom of the groove alternates between two different depths in accordance with the signals. A master record so produced may be coated with nickel which is then removed to form a stamping master for the production of disc replicas of the type described in Specifications 1,392,204, 1,392,205 and 1,392,206 for playback by means of capacitance variation as described in Specifications 1,392,201 and 1,392,202.
