ABSTRACT:
Write heads and corresponding methods of fabrication are provided using multiple electronic lapping guides to collect information regarding multiple distances of a write head, such as a throat height and a flare point distance of a write pole. A method of fabricating a write head includes fabricating a write pole and a corresponding write pole ELG. The method further includes fabricating a trailing shield and a corresponding trailing shield ELG. The method further includes performing a lapping process on the write head, and monitoring a lapping depth of the lapping process based on the resistance of the write pole ELG and the resistance of the trailing shield ELG.
