ッド型PCM磁気記録再生装置。A recording mark indicating a predetermined track angle to be recorded on a magnetic tape traveling while being wound around a head cylinder so as to indicate a predetermined tape wrap angle, or the above-described predetermined tape wrap angle. The magnetic tape is wound at a predetermined helix angle so as to draw a trajectory that coincides with a recording trace showing a predetermined track angle recorded on a magnetic tape running while being wound around a head cylinder as shown in FIG. A magnetic head that rotates while drawing a trailing trajectory, a means for switching the running direction of the magnetic tape in both forward and reverse directions, and corresponding to the switching of the running direction of the magnetic tape in the forward and reverse directions,
- A means for switching the direction of rotation of the magnetic head from forward to reverse, and when the magnetic tape runs in the forward direction, the area from one end to near the center in the width direction of the magnetic tape is used for recording and reproduction. In addition, when the magnetic tape is run in the opposite direction, the magnetic tape is head, by PCM
A rotary head type PCM magnetic recording and reproducing device that performs signal recording and reproducing operations.
