Abstract

PURPOSE: To improve the distribution of write-in magnetic field for heads, by forming the non-magnetic Zn ferrite film on one side of a pair of ferromagnetic ferrite blocks so that the gap width can be obtained, and laminating other blocks with pressing under heat.
CONSTITUTION: In the manufacture of the magnetic disc unit magnetic head, two sets of ferrite blocks 2 are machined in U-shape and the end surface 11 is mirror polished. The block 2' is formed by forming the Zn ferrite film 5 on another block 2 in sputtering. The blocks 2, 2' are laminated and pressed under heat, and after bonding them, the head core 9 is obtained with cut in a given width. The core 9 is inserted to the hole 8 of the slider 7 and bonded and winding 10 is made to finish the magnetic head. Thus, the gap 5 is formed with the same ferrite material as the core 2, and since no roundness is caused at the gap edge in polishing the disc opposing surfaces, the distribution of write-in magnetic field can be increased and the characteristics can be improved.
