1. A digital data reproducing apparatus for reproducing digital data in variable length encoded form from a disk, comprising:

  • pickup means for picking up the digital data from the disk;

    first storage means for storing the digital data and for reading the stored digital data therefrom at a first variable rate;

    second storage means for storing the digital data read from the first storage means, the second storage means being operative to store the digital data at said first variable rate and to read the digital data stored therein at a second variable rate varying within a predetermined range inching at least one value higher than a maximum value of said first variable rate;

    inverse variable length code means for inverse variable length code processing the data read from said second storage means to produce inverse variable length code processed data, the inverse variable length code means being operative to receive the data at said second variable rate; and

    jump controlling means for causing said pickup means to track jump in accordance with an amount of data stored in said first storage means.
