Manufacture for magnetic head

Abstract

Abstract PURPOSE: To establish the magnetic head with good accuracy of size, by thermally pressing two types of small bases of the ferrite base on which a plurality of winding window grooves are made with a given interval and the bare base without the windows for specified length each other, after track processing respectively. CONSTITUTION: A plurality of ferrite bases 1 are transversally placed on the tool 5, tentative grooves 11 are processed by using grindstone formed into winding window groove shape, the winding window grooves 12 are made with an interval corresponding to the height C of the winding window grooves, and further, the winding window grooves 13, 14, 15 are machined with equal distance. Next, the ferrite base 1 is cut at the tentative grooves 11, the ferrite base 1 is sequentially cut with the pitch of the size C plus the depth of gap E to obtain a plurality of ferrite small bases 4'. Separately, the ferrite base without winding window groove machining is similarly cut to obtain small bases 4", and the small bases 4' and 4" are thermally pressed after track processing to form the gap 9. The magnetic head is obtained with shaping. COPYRIGHT: (C)1981,JPO&Japio
