Abstract:
A recording/reproduction apparatus for a digital video signal and/or a digital audio signal, comprising:a circuit switching a recording operation and a reproducing operation intermittently; a circuit time-base-compressing the video signal or the audio signal to be recorded; a circuit recording the time-base-compressed signal in said disk-like recording medium; a circuit controlling the rotation of said disk-like recording medium in such a manner as to secure a Predetermined rotational speed during a recording period and to hold the same rotational speed in a reproduction period as in the recording period; a circuit reproducing a signal from said disk-like recording medium; a circuit time-base-expanding the reproduced signal from the reproducing circuit; and a circuit continuously outputting the time-base-expanded signal as a video signal and/or an audio signal; wherein said switching circuit switches between a recording period tr (tr: real number) and a reproduction period tp (tp=tâˆ’tr) into which a predetermined cycle t (t: real number) is divided, and said rotation control circuit controls the rotation in such a manner as to secure a predetermined rotational speed during the period tr and to hold the last rotational speed of the period tr during the period tp.
