Abstract
1,044,054. Recording and playback. RADIO CORPORATION OF AMERICA. March 5, 1964 [March 8, 1963], No. 9451/64. Heading G5R. An arrangement for recording and reproducing signals comprising transducer 24 movable in a circular path about a predetermined axis and means for moving a record medium 15 in a helical path about the axis whereby the transducer 24 scans obliquely across the medium, is characterized in that a control system determines the effective diameter of the helix. In a magnetic tape recording system for recording signals using frequency modulation with a 4 Mc/s. bandwidth, the control system comprises a pair of transducers 46, 47 for recording control pulses along the edges of the tape during «record.» During playback, any phase difference between these pulses is sensed in a phase detector 58 and the resulting error signal is used to control the torque of the supply reel motor 14, thus varying the tape tension and hence the effective diameter of the helix. The control pulses are generated by a tone wheel 48 on the shaft driving the transducer 24, the same pulses being also used to control the speed of the head reel motor during playback. Instead of utilizing separate control signals, the information may be derived from the edges of the diagonally recorded signals.
