ABSTRACT:
A pair of detecting heads are disposed in positions corresponding respectively to single heads at both ends of a multichannel head unit, symmetrically inclined with respect to the tape traveling direction. The center positions of these detecting heads are severally in alignment with the center positions of tracks of a magnetic tape. The phase difference between track playback signals reproduced respectively by these detecting heads is detected, and a tracking error is corrected in accordance with the phase difference.
