Abstract
In a method of manufacturing a flying magnetic head, the following surfaces are mirror-finished: a bonding surface 18a of a core block 18, a surface 18b of the core block 18 which is on the opposite side of the bonding surface 18a, a surface 19a of a core block 19, and a bonding end surface 2a of a slider 2 formed of a non-magnetic material such as ceramics and having a rectangular sectional configuration. Then, high-melting-point bonding glass layers m are deposited on these surfaces by sputtering or the like. Afterwards, the core blocks 18 and 19 and the slider 2 are put together and simultaneously bonded with each other by heating under pressure through the bonding glass layers m, thereby forming a flying magnetic head block.
