    摘要: An apparatus for recording and reproducing a video signal and a PCM audio data sampled by a sampling frequency being asynchronous to a field frequency of a video signal. The apparatus enables to record and reproduce the digital data formatted at each field. The apparatus includes an address control circuit for switching the number of sample values to be recorded per field and a clock generating circuit. The clock generating circuit provides a VCO for forcibly stopping the switching of the number of the sample values, keeping the number of the sample values constant and generating a sampling clock being synchronous to a field frequency, based on a signal sent from an input terminal for a selecting signal. When recording a different digital data from the PCM audio data, the sampling clock sent from the clock generating circuit is used in the address control circuit.
