Abstract
PURPOSE: To increase the rate of glass filling in the groove and to enable massproduction stably, by providing the flat part which determines the width of glass filling in groove at the cut-away part of the core between the track width restriction grooves 0.3 mm or less in width.
CONSTITUTION: The grooves 5,6 and 5',6' 0.3 mm or less in width are sequentially formed on the blocks 1 and 2 made of high permeability magnetic material and providing the coil winding groove 3 at one end with a given pitch other than the flat parts 4,4'. The flat part 7 which is thrown away at core cut is formed between the grooves 5,5' and 6,6', one set with two grooves. Further, the front part of the gap opposing surfaces 8,9 is provided with the SiO2 films 10,11 and the back gap part is with the lead system low melting point glasses 12,13. When the blocks 1 and 2 are bonded with heat, the reinforce glass is filled in the grooves. The block 20 finished for the gap formation is cut off at the tilt line 23, the tape opposing surface is machined in cylindrical shape, and the magnetic head core 22 is finished for machining, in which the width of the track part 4 is smaller than the thickness of the core 21.
