Abstract

796,251. Magnetic recording and reproducing apparatus. TOCHIHARA, S. June 19, 1956 [June 20, 1955], No. 19010/56. Class 40 (2). Apparatus for magnetic recording and reproducing comprises a record sheet 1 with a magnetic coating on one side and visual information, such as a language translation, on the other, a glass plate 2 superposed over the latter side, and relatively moving transducer heads pressed against the magnetic coated side. In one embodiment a continuous record is made by four separate transducers a, b, c, d which are mounted on a turntable 5 and perform parallel record traces a<SP>1</SP>, b<SP>1</SP>, c<SP>1</SP>, d<SP>1</SP>, respectively, on a relatively moving record sheet 1, one trace commencing at the same instant as the previous one finishes. Straight traces of a similar kind may be made by transducers mounted as in Fig. 3. A zig-zag trace may be obtained by a reciprocating movement of the transducer, or a spiral one by moving the transducer relatively along a spiral path.
