Abstract

850,963. Magnetic reproducing apparatus. NATIONAL RESEARCH DEVELOPMENT CORPORATION. March 4, 1957 [March 7 1956], No. 7120/56. Class 40 (2). Relative movement between a magnetic reading head 1 and a magnetic record 3, other than that of simple feed of the record (which may be too slow or non-existent) is used to induce a readable output from the head. As shown the record 3, normally fed by a pinch wheel 5, is vibrated transversely towards and away from the head 1 by a vibrating pulley or other member mechanically coupled to the tape, by the electrostatic effect of an alternating potential applied between the tape and a fixed plate, or by sound waves from a loud speaker 11. Specifications 751,360, 791,902 and 824,653 are referred to.
