ABSTRACT:
A flying-type magnetic head includes a magnetic head chip composed of a pair of cores, each having a metallic magnetic thin film thereon which faces a magnetic gap. The magnetic chip is inserted and fixed in a slit provided in a non-magnetic slider at the outlet side of a magnetic recording medium generating airflow across an air bearing. The back of the slider is fixed to a gimbal in such a manner that a flying plane portion of the magnetic head faces the magnetic recording medium. The height at the flying plane portion of the slider is structurally controlled such that the height where the back of the slider is fixed to the gimbal differs by 20 nm or less with respect to the height thereof when the back of the slider is not fixed to the gimbal. The magnetic head chip may be composed of a pair of non-magnetic cores, each of which has a metallic magnetic thin film deposited thereon.
