Abstract
766,434. Magnetic recording and reproducing apparatus. JOHNSON, A. E., and CONWAY, T. D. Sept. 3, 1954 [June 9, 1953], No. 15834/53. Class 40 (2). In a magnetic recording and reproducing apparatus for language instruction a record tape has two tracks, means being provided to reproduce from both tracks, but to record on only one of the tracks. One track on the tape carries a permanent recording of words or phrases interspersed with a control signal, while the other is able to receive and reproduce a recording made by a person imitating the speech heard on the permanent record. Reproduction of the permanent, record is effected by a head 18, amplifiers 22 and 24, and loudspeaker 25. Erasing and recording or reproducing on the other track is effected by erazing head 19 and transducer 20, but the circuit of the latter is only completed when contacts 23b of a relay 23 are closed by the rectified current from the control signal on the permanent record track. A pair of contacts in parallel with contacts 23b energize a signal lamp to indicate that a recording may be made.
