Abstract

770,465. Recording sound. DECCA RECORD CO., Ltd. Aug. 9, 1955 [Aug. 10, 1954], No. 23266/54. Class 40 (2). In a recording apparatus of the kind described in Specification 708,570, in which the groove spacing is automatically varied in accordance with the volume of sound being recorded, means are also provided to vary simultaneously the depth of the groove in accordance with such volume. For this purpose the output from the motor-generator 20 controlling the speed of rotation of the leadscrew is also utilized to energize a solenoid 36 which causes additional pressure to be applied to a stylus 30.
