Abstract
An improved video signal recording and reproducing apparatus for a digital video cassette tape recorder by which it is possible to divide, record and reproduce a digital video signal on a low density video tape into multiple tracks based on the amount of data recordable on one track of a high density video tape by controlling a recording/reproducing speed and a tape running speed in accordance with a judgement of the type of the video tape having a predetermined recordable wavelength. The apparatus includes a detector for detecting the type of the video tape in accordance with a recordable wavelength of the video tape, a judgement section for judging the type of the tape by receiving a detected tape type signal from the detector, and a controller for controlling a recording and reproducing speed in accordance with the judged tape type.
