ABSTRACT:
A digital video signal reproducing apparatus adapted for reproduction of a magnetic tape where video data of one field are recorded on a plurality of tracks by a plurality of rotary heads. Playback heads employed for such reproduction are mounted on bimorph bases or the like so that the vertical positions or heights of the playback heads are controllable and, if any of the playback heads is rendered faulty by some reason, the vertical positions thereof are controlled to select the order of the tracks from which the video data are to be reproduced, whereby required correction can be carried out with interfield concealment of the reproduced video data to consequently avert deterioration of the image quality.
