Abstract
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.
