<p>In a method of and apparatus for recording a digital information signal, an information signal to be recorded is pulse-code-modulated (PCM) and the PCM signal is recorded on a recording medium by a rotary head, as slanting tracks (T) with no guard bands between adjacent tracks, and then reproduced therefrom. A tracking pilot signal (P) is recorded on a part or parts (PT1, PT2, PT3) of each track (T) independently of the PCM signal. The recording positions of the pilot signals (P) on respective tracks (T) are deterined in such a manner that, as viewed from a direction perpendicular to the tracing direction (13) of the rotary head, the positions are not superimposed upon one another, that is they do not overlap one another. Upon reproducing, when a recorded 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> |
