Abstract

808,096. Magnetic recording and reproducing apparatus. HOLLOWAY, C. E. Jan. 29, 1957, No. 3187/57. Class 40 (2). A magnetic recording tape 1 has a transparent section 8. Light from a source 6 passes through the section 8 to a photo-cell 7 and amplifier 9 producing a signal voltage of sufficient strength to operate a relay and change the operating conditions of the machine, e.g. to immediately replay a recording or to stop the machine. The area 8 may alternatively be made reflective in which case the light source and photo-cell are on the same side of the tape.
