Abstract

PURPOSE:To obtain a magnetic head having a good contact to the magnetic tape, by giving the finishing process to the magnetic head with the lapping tape which runs in a fixed speed nearly equal to the tape speed when the magnetic head is used. CONSTITUTION:Cylinder 15 starts simultaneously with the start of motor 5, and rod 13 of the cylinder ascends in the speed according to the divergence of flow rate control valve 14. Then pressure roller 10 is pressed by driving roller 7 after a fixed time, and lapping tape 2 is pressed between rollers 7 and 10 to be made to run. In that ease, roller 10 is pressed by roller 7 a little more slowly than the start of motor 5. And this delay time, i.e., the shift speed of roller 10 can be controlled in accordance with the running speed of tape 2. Accordingly, even in case tape 2 is run in >=3m/sec. speed, a smooth rise is possible for the tape. Thus a magnetic tape having a good contact performance can be obtained.
