PURPOSE:To eliminate a dip and prevent a waveform from getting out of shape, by putting an nonparallel tip part on the outside of a track at a reproducing time. CONSTITUTION:Since demerits of an unparallel head is due to a nonparallel tip part F, the tip part F is put on the outside of the track at a reproducing time. When the tip part F is put on the outside of the track, an output voltage 3'' outputted from the tip part F is flat and low, and therefore, the dip is eliminated almost. Further, the space loss is recovered. Th reason why the space loss is recovered is because an output voltage 3' outputted from a nonparallel part middle M is lower than said output voltage 3''. |
