PURPOSE:To reduce crosstalk quantity and achieve the improvement in track density by providing azimuth angle to two magnetic head cores relating to recording and reproducing of magnetic discs thereby inclining and recording information. CONSTITUTION:A ferrite block 12 given with an arbitrary angle 11 on one side only is formed and the tapered face is finished to a mirror surface 13. The angles 16 of tapered faces 15 and grooves 17 of the same angle as the angle 11 are formed to a hexagonel ferrite block 14. Next, the blocks 12 and 14 are so combined that the mirror face 13 and faces 15 overlap and these are bonded by glass, whereby two non-parallel gaps 18 are formed. By integrating these two gaps and providing optimum azimuth angle in this way, the mutual effect between the tracks is reduced and the increase in the recording density of information may be achieved. |
