PURPOSE:To inexpensively manufacture a magnetic head in which chipping is prevented from occurring and with superior abrasion resistance and high accuracy, by forming both side planes of a gap as planes in which the width of the sliding surface of a tape are set as track width, and forming nonmagnetic hardened thin films on the planes. CONSTITUTION:The sliding surface of the tape of a block 13 in which ferrite are joined is ground, and a groove 12 is ground leave the same width as the track width, and a hardened nonmagnetic thin film 4 is vapor-deposited on the upper surface. Next, only a cylindrical plane is ground, and the thin film 14 is left in the groove 12, and after slicing a groove part, a magnetic core 7 can be obtained. The size between parts 8 is the track width at the time of forming the groove 12, and both planes are covered with a hardened film 9. Therefore, it is possible to prevent the chipping from occurring and to manufacture the head with superior abrasion resistance and high accuracy inexpensively. |
