IPC: G11B7/00
Filed: 1930-03-10
Abstract: 350,531. Recording and reproducing sound &c. PRISNER, S. and WENDER, E., 1, Mowbray Road, Kilburn, London. March 10, 1930, No. 7773. [Class 40 (ii).] Apparatus for effecting exploration of a surface by a spot of light in a series of parallel straight lines in recording or reproducing sound or other variations comprises means for focusing a spot of light upon a helical or curved mirror mounted upon a rotating drum or disc respectively. As shown in Fig. 1, a helical mirror 8, disposed normally to the surface of a drum 7, reflects light from a source 4 on to a moving light-sensitive film 9 so as to produce a record in the form of a series of parallel lines of the sounds impressed on a microphone 1. The microphone is connected with an amplifier 2 and light relay 3 whereby the intensity of the light from the source 4 is varied. For reproducing from a sound record the light beam is caused to explore a record 9, Fig. 2, in a series of parallel lines and after modulation by such record is adapted to fall upon a second mirror 10 helically arranged on a drum 11 and is reflected therefrom on to a photo-electric cell 12. If desired, curved prisms may be employed instead of mirrors. Kinematograph pictures may be interposed between adjacent sound-trace lines. Specifications 332,615 and 337,151, [both in Class 40 (ii), Phonographs &c.], are referred to. The Provisional Specification describes also the use of rotary lenses in place of mirrors.
