ABSTRACT:
There is provided a recording/reproducing apparatus, e.g., digital video tape recorder, etc., applicable to a transmission system sufficiently utilizing communication capacity. The recording/reproducing apparatus comprises a recording element (e.g., rotary head) for recording, onto a recording medium (e.g., magnetic tape), time base compression processing implemented digital data delivered from the external, e.g., broadcasting station side, etc.; a control circuit for carrying out a control to read out the digital data from the recording medium at a speed lower than a recording speed in dependency upon the time base compression processing implemented to the digital data; and an output circuit for outputting, as a reproduced output, digital data which has been read out from the recording medium. In addition to the above-mentioned ordinary reproduction, in the case of carrying out fast-feed reproduction or rewinding reproduction, the control circuit carries out a control such that the magnetic tape runs at a higher speed, and the output circuit selects and outputs only valid digital data of digital data obtained by tracing of the rotary head.
