Title: Magnetic head
Inventor: MATSUYAMA HIROSHI
IPC: G11B5/265
Filed: 1983-02-03
Abstract: PURPOSE:To make the magnetic flux generated by magnetism in a medium insensible in an erasing head by a recording and reproducing head, and to reduce erasure crosstalk greatly by making depth-directional angles of the recording and reproducing head and erasing head different. CONSTITUTION:When a recording current flows through a coil 1, cores 13 and 15 are excited to produce a recording magnetic field by an R/W gap 18. In a figure, 12 is the distribution of the produced magnetic field. Then, magnetism shown by 21 is left on the medium. The erasing head erases both sides of a recorded track for trimming. The gap 19 of the erasing head is opposite in direction to the gap 18 of the recording and reproducing head in the gap depth direction, so magnetic flux originating from magnetism in a direction 21 is made insensible. Therefore, the erasure crosstalk is made less in an off-track state than that of a conventional head.
