1. A data reproduction apparatus comprising:

  • data reproducing means for reproducing data, which is recorded on a recording medium at a variable transfer rate, at intermittent cycles and providing a signal indicative thereof;

    data storage means, responsive to the signal from said data reproducing means, for storing therein the data reproduced by said data reproducing means;

    decoding means for decoding the data reproduced by said data reproducing means to provide a reproduction signal in sequence;

    reproduction controlling means for controlling operations of said data storage means and said decoding means, said reproduction controlling means transferring the reproduced data stored in said data storage means to said decoding means so as to allow said decoding means to provide the reproduction signal in sequence; and

    data control signal outputting means for controlling output of the stored data from said data storage means and for outputting a data control signal to said data storage means;

    wherein said reproduction control means selectively provides a reproduction enable signal and a reproduction inhibit signal to said data reproducing means according to the amount of the reproduced data stored in said data storage means to perform a data reproduction operation of said data reproducing means at the intermittent cycles, said data reproducing means having a reproduction element, said data reproducing means being responsive to the reproduction enable signal to have the reproduction element trace a data-recorded track provided on the recording medium to read recorded data therefrom and also responsive to the reproduction inhibit signal to stop the data reproduction operation thereof while allowing the reproduction element to trace a following portion of the data record track, when said reproduction control means provides the reproduction enable signal after providing the reproduction inhibit signal, said reproduction control means moving the reproduction element to a portion of the data record track immediately before a portion where the data reproduction operation has been stopped in response to the reproduction inhibit signal.
