摘要： Two floating rails are provided on a slider of a floating magnetic head. Rear portions, in the advancing direction of a floating magnetic head with respect to a magnetic recording medium, of the respective floating rails are cut out. That is, the floating rails exist only in front of the cut-out portions. An auxiliary rail is formed in the rear of one of the floating rails. The auxiliary rail is narrower than the floating rail, wider than the track width of an electromagnetic conversion element, and approximately as high as the floating rail. The electromagnetic conversion element is provided at a rear portion of the auxiliary rail.

摘要： 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.
