ABSTRACT:
A method of manufacturing a magnetic head comprises the steps of forming between a pair of core blocks to be joined together gap holding surfaces arranged relative to a gap forming surface, in the core blocks, such that gaps formed between the gap holding surfaces, within which spacers are placed, will be wider than the gap formed between the gap forming surfaces between which there is provided a molten gap forming material forming an effective magnetic gap in the finished head having a width of about 1.mu. by slightly permeating the molten gap forming material within the core block.
