摘要： An improved video signal recording and reproducing apparatus and a method thereof for a digital video cassette tape recorder, which are capable of recording and reproducing a digital video signal using a common video tape by maintaining a normal recording/reproducing speed when a high density tape is used by judging the type of the tape having a predetermined recording wavelength, dividing and recording the digital video data in multiple tracks by changing the recording/reproducing speed in case of a low density tape, and recording a block division information corresponding to the divided tracks, which includes a controller (27) for variably controlling a recording/reproducing speed (25) by judging the type of the video tape (28) in a recording or reproducing mode, a formatter (21) for inserting a block division information into a track of the video tape in the recording mode and for removing the block division information in accordance with a track reference signal during reproduction when varying the recording/reproducing speed, and a clock selector (26) for selectively outputting a predetermined clock signal which is appropriate for the recording/reproducing signal processing when varying the recording/reproducing speed.
