ABSTRACT:
A magnetic read head of either CIP or CPP configuration is disclosed having a read sensor having oxidized non-conductive regions. The read sensor has a front edge, a rear edge, a left-side edge and a right-side edge. For a CIP configuration, the front edge and the rear edge are oxidized to form non-conductive regions. For a CPP configuration, the left-side edge, the right-side edge, the front edge and the rear edge are oxidized to form non-conductive regions. Also disclosed are a disk drive including a read sensor having oxidized non-conductive regions, and a method of fabrication for a read sensor having oxidized non-conductive regions.
