Abstract: 1373511 Forming record grooves by electron beams DECCA Ltd 27 April 1972 [28 April 1971] 11993/71 Heading G5R A modulated groove is formed in a thin, electrically resistive, thermoplastics film 1 disposed on a conductive member 2, by means of an intensity-modulated electron beam 3 which deposits electric charge 5 on the relatively moving film 1, the film 1 being softened by a heater 6 so that the surface thereof deforms at 7 under the influence of electrostatic forces, the impingement of the beam 3 being also controlled to produce a groove of suitable cross-section, preferably triangular, by depositing a track of charge which is wider than the beam's effective diameter along the track, and has a density greater at the track centre than at the edges. The beam 3 is thus oscillated transversely to the track to cause charge deposition twice at each point, and is intensity-modulated by a combination of a frequency-modulated signal (J), Fig. 6 (not shown), constituting the signal to be recorded, and two other signals (K, L) at twice the oscillation frequency. A spiral groove is formed in a disc-shaped film 11, Fig. 4, by rotating the disc on a shaft 13 and traversing the disc by means of a feed screw 23. Heating of the  film takes place either before or after the charge deposition, by an infra-red or radio-frequency heater 35. The angular and linear positions of the disc are sensed by a grating 25 and an interferometer 30, and are compared at 33 in order to control the feed screw motor 24. A metal film may be evaporated on to the disc and the track may be then played back by a method described in Specification 1,373,512. The metal film is then thickened by electroplating and removed to form a negative from which pressings may be made.
