Abstract

PURPOSE: To improve the yield on products by providing a separating groove between a couple of glass insertion grooves in manufacture of a magnetic head core where a couple of core materials provided with fixed grooves are connected by molten glass.
CONSTITUTION: On the junction surface of core material 8, separating groove 16 (to width W or more than approximate 16μ and depth D nearly one and half times as deep as track specification groove 1) for a glass flow adjustment is provided and then several track specification grooves 1 are also provided crossing it. On the junction surface of core material 9, on the other hand, groove 17 meeting the above- mentioned separating groove 16 and glass insertion grooves 12 and winding hole grooves 11 on both its sides are provided, and several track specification grooves 1 are also provided crossing grooves 11, 12 and 17. Next, after a couple of the above- mentioned core materials 8 and 9 are made in contact through vapor-deposited film 4, glass blocks 13 are inserted into respective grooves 12 and molten by heating to fill gaps between core materials 8 and 9 and materials are cut into individual core blocks, which are sliced along grooves 1 to obtain magnetic head cores.
