ABSTRACT:
In a recording/reproduction apparatus equipped with an integrated head comprising a thin film inductive write element and a MR read element and mounted on a head slider which is arranged to be rotatable about a point so as to be rotationally accessible to tracks of a disk serving as a recording medium to make yaw angles with respect to tangents of the tracks, the inductive write element and the MR read element are arranged so that a magnetic center line of the MR read element which extends in directions perpendicular to track crossing directions is separated from a geometric center line of the MR write element which extends in directions perpendicular to the track crossing directions. The separation between the inductive write element and the MR read element is determined as the result of a multiplication of 1/2 of the sum of the sine of the slider yaw angle with respect to the tangent of the innermost track on the disk and the sine of the slider yaw angle with respect to the tangent of the outermost track by the distance between a gap of the inductive write element and the center of the MR read element. This arrangement allows minimizing the off-track between the write and read modes which occurs due to the yaw angles.
