Abstract
PURPOSE: To obtain the magnetic head excellent in characteristic at low cost, by forming a groove with a prescribed core width to the opposing planes of recording medium, after bonding the C type core bonding nonmagnetic substance to both sides of magnetic substance to the block consisting of a magnetic substance.
CONSTITUTION: A slider 8 of nonmagnetic substance material of a ferrite material 9 is bonded with high melting point glass and a C type core 10 is formed by cutting it to a prescribed length. Next, after bonding a block made of the C type core 10 and a magnetic substance material with low melting point glass, to keep minute and stable the air gap between the magnetic head and the magnetic recording medium, a groov is formed in parallel with the direction of revolution of the magnetic head, and to keep the core width to a prescribed size, a slit groove 12 is processed to finish it to the magnetic head. Thus, glass bonding can be two processes, thereby suppressing the extent of thermal stress to the core material.
