Abstract
It is assumed that W is the width for an end face of the lower magnetic shield thin film which is exposed outward from the tape sliding surface . It is also assumed that W corresponds to the sum of the width for an end face of the MR element which is exposed outward from the tape sliding surface and widths for end faces of a pair of ferromagnetic films and which are exposed outward therefrom. The width W is determined to be smaller than W . When the MR head is mounted on the head support plate or the rotary drum , it is possible to use as a marker the lower magnetic shield thin film 's end face exposed from the tape sliding surface.
