A data recording apparatus reverses the bit order of each of n-bit codes assigned respectively to 2n frame data in the order of a normal-speed play, rearranges the frame data based on the reversed n-bit codes, and then records the rearranged frame data in that order onto a recording medium. A data reproducing apparatus reads out, from the recording medium, frame data corresponding in number to the reciprocal of the multiple in an aimed play speed and stored the read-out frame data in a buffer memory or the like. The data reproducing apparatus then reads out the stored frame data from the buffer memory or the like in a predetermined order in accordance with the aimed play speed. The data reproducing apparatus can realize such a high-speed play as were more than its data read performance. Besides, wasteful operations in a high-speed play can be eliminated and the load on the reading head unit of the data reproducing apparatus can be relieved.
