ABSTRACT:
A MR element includes a MR layer with a strip shape extending in a track width direction. The MR layer has a surface located at a front end edge of the layer, to be opposed to a magnetic medium, and a tapered portion located at a rear end edge of the layer. In order to define the height of the MR layer, a length of the tapered portion along a direction perpendicular to the track width direction (L) is determined to substantially 1/5 or less, preferably 1/10 or less of a distance between the front end edge and the rear end edge of the MR layer (h.sub.MR).
