Abstract

PURPOSE:To achieve close recording effectively by reducing the overall width of a magnetic core half body gradually toward a back core side, and then securing the resulting increase in magnetic resistance by increasing the core thickness of a corresponding part. CONSTITUTION:A core half body 17 has overall core width equal to track width on a medium contacting surface side and decreases in overall width gradually to the back core side, and the core half body 17 collides with a core half body 10. This core half body 17 increases in thickness gradually from the medium contacting surface side to the back core side. The inclination of the increase in thickness is matched with that of a decrease in overall width, and the magnetic resistance in a magnetic circuit is made nearly constant on the whole.
