发明名称 MAGNETIC HEAD DEVICE AND ITS PRODUCTION
摘要 PROBLEM TO BE SOLVED: To suppress the deterioration in C/N occurring in the occurrence of an adjacent erasure and to enable mass production by varying the butt surface widths of the core half bodies of a magnetic head element and disposing an azimuth angle within the opening angle of a magnetic gap. SOLUTION: The magnetic core of the magnetic head element is formed by butting the magnetic core half bodies 1, 2 against each other by the butt surfaces 1a, 2a of the width different from each other and joining the surfaces. The angle formed by the normal of the bisector of the opening angleβin the one end (p) of the magnetic gap (g) and the longitudinal direction M of a magnetic tape is increased to allow the azimuth angleθto exist within the opening angleβ. The magnetic head device of a metal-in gap is constituted by disposing the magnetic head element obtd. in such a manner. The equivalence to the case where the butt surface widths 1a, 2a of the magnetic core half bodies 1, 2 facing each other of the respective magnetic head elements are exactly aligned is thereby attained. Then, the amt. of the adjacent erasure which occurs is lowered to a negligible level and the easy and sure mass production is made possible.
