ABSTRACT:
In an apparatus, for example, an 8-mm format VTR, for selectively reproducing video data and digital data, such as, PCM audio data, recorded on a magnetic medium with any one of a plurality of recording densities, the recording density of the digital data is detected on the basis of a characteristic of the reproduced digital data, such as, a characteristic clock frequency regenerated therefrom, and the processing to which the reproduced digital data is subjected is selected automatically in accordance with the detected recording density thereof, thereby facilitating the use of the apparatus for reproducing digital data recorded with different densities.
