<p>A method and an apparatus for recording a digital information signal are disclosed in which a signal to be recorded is pulse-code-modulated (PCM) and the PCM signal is recorded on a recording medium by a rotary head as a slant tracks with no guard band between adjacent tracks and then reproduced therefrom. In this case, a tracking pilot signal is recorded on a part of each track independently of the PCM signal. The recording positions of the pilot signals on respective tracks are determined in such a manner that succeeding three tracks are seen from the direction perpendicular to the tracing direction of the rotary head, they are not superimposed upon one other. Upon reproducing, when the record track is traced by the rotary head, the pilot signals from both tracks adjacent to the track to be traced are reproduced and a tracking signal is generated from the reproduced outputs whereby a playback rotary head traces the record track.</p> |
