Abstract
747,787. Magnetic sound recording and reproducing apparatus. ROHLING H. Jan. 15, 1954 [Jan. 16, 1953]. No. 1323/54. Class 40(2) Either one of a pair of spools carrying a magnetic wire or tape is brought into 'driving engagement with a shaft or one of a pair of shafts by inverting a cassette containing the spools. As shown spools 1, 4 are freely and slidably mounted on a shaft 14, the uppermost spool being in engagement with a piece 3 of velvet on a disc 2 secured to or integral with the shaft, while the lower spool engages a disc 5 of paper on the wall 6 of the cassette. Due to the frictional engagement of the spool 1 with the disc 2, the spool is driven to wind a magnetic wire from the spool 4 through a tubular guide 8, a groove 9 in the disc 2, past a magnetic head at 11, through a tubular guide 10, and into the spool 1. On inversion of the cassette, the spool 4 rests on the velvet piece 3 on the other side of the disc 2 to reverse the direction of winding of the wire. The cassette may be mounted on the turntable of a record playing mechanism, the shaft 14 having a member for coupling it to the turntable spindle. Two or more cassettes may be driven simultaneously by placing one on top of the other. A record may be erased by bringing the whole cassette into a magnetic field. A wire record may be made of austentic steel, and may have a diameter of less than 0.45 m.m.
