发明名称 Verfahren zur Herstellung eines Magnetkopfes.
摘要 A method for manufacture of a bulk-type magnetic head capable of performing a frame recording operation. In sequential steps, coil grooves (3,4) and track-width limit grooves (17,18) substantially orthogonal thereto are formed in respective butt surfaces (1a,2a) of a pair of magnetic core blocks (1,2), and then head-element division slits (19,20) are formed between the track-width limit grooves (17,18). Subsequently the magnetic core blocks are joined to be integral with each other, and notches (22) are formed in the core blocks (1,2) in such a manner as to extend from lateral surfaces of the core blocks on the reverse side with respect to the butt surfaces (1a,2a) thereof and to reach at least the coil grooves adjacently to the head-element division slits (19,20), whereby the in-line precision of magnetic gaps can be enhanced and high productivity is attained in manufacture of the magnetic head. <IMAGE>
