摘要： PURPOSE: A thin film magnetic head is provided, which decreases a change and a noise of a reproducing output when reproducing. CONSTITUTION: The thin film magnetic head comprises: a lower magnetic core (1) to be formed on a substrate; an upper magnetic core (2) to be oppositely installed to the lower magnetic core (1); a coil (187) to be arranged between the lower magnetic core (1) and the upper magnetic core (2); and an insulating layer for insulating the lower magnetic core (1), the upper magnetic core (2) and the coil (187) each other, wherein a front end portion of the lower magnetic core (1) and the upper magnetic core (2) has an identical width with a track width near a magnetic gap film (3) and a rear end portion of the lower magnetic core (1) and the upper magnetic core (2) has a greater width than the front end portion. Thereby, it is possible to decrease the change and the noise of the reproduction output in the thin film magnetic head with a magnetic resistor effect type.
