发明名称 ROTARY HEAD TYPE PCM RECORDING AND REPRODUCING DEVICE, ROTARY HEAD TYPE PCM REPRODUCING DEVICE AND ROTARY HEAD TYPE PCM REPRODUCING SYSTEM
摘要 <p>PURPOSE:To continuously execute the consecutive recording of a magnetic tape by inverting the output signal of an edge detecting circuit delayed by two frames from the rising edge of a recording / reproducing switch control signal and passing the output of a switching circuit through an OR circuit. CONSTITUTION:A recorded signal to be outputted from a switching circuit 57 is supplied to an OR circuit 59. On the other hand, when a recording / reproducing switch control signal F is the reproducing mode of 'L', a circuit 50 for edge detection outputs the signal of 'H' to the circuit 59 and the circuit 59 interrupts the output signal of the circuit 57. However, when the signal F is changed from 'L' to 'H', the output signal of the circuit 50 is inverted from the 'H' to 'L' delayed by the two frames from this rising edge and the output signal of the circuit 57 starts passing through the circuit 59. Thus, after the two frames and later from the rising edge of the signal F, a recorded signal E is obtained in an output terminal 65 and recording is started. Accordingly, the frame address of a leading track for the consecutive recording on the magnetic tape is continuous to the frame address of the preceding track.</p>
