ABSTRACT:
A method of making a magnetic recording and/or reproducing head having a head support and a head core. The head core is inserted in a slit defined in the head support and is retained in position on the head support by means of a fixing jig to hold the head core immovable relative to the head support. Thereafter, a glass frit for temporarily fixing the head core relative to the head support is fused by the application of a laser beam to partially connect the head core and the head support together. After the fixing jig has been removed and a glass frit has been mounted on the head support so as to cover the slit above the head core, the assembly is loaded into a heating furnace to fuse the glass frit thereby to permanently interlock the head core and the head support together.
