Abstract
738,965. Recording and reproducing sound. JONES, E. W. Dec. 22, 1953, No. 35641/53. Class 40 (2). In a sound-recording apparatus the distortion and variation in depth of the groove section, Fig. 7, caused by the arcuate passage, Fig. 4, of a stylus pivoted on an axis 17 parallel to the record 20, is avoided by making the stylus 10 right-angled in shape, Fig. 2, and pivoted on an axis at right-angles to the record surface.
