High accuracy tape bearing surface length definition process by closure lapping for tape head fabrication

摘要

A method according to one embodiment includes coupling closures to a section having a plurality of rows of transducers formed on a substrate, the closures being coupled to the section on an opposite side of the transducers as the substrate. The section is coupled to a lapping-resistant guide, where the closures protrude beyond a lap-stop end of the guide. The closures are lapped for shortening the closures in a direction toward the transducers, wherein the lapping is terminated after the guide contacts a lapping surface. A method according to another embodiment includes coupling closures to a section having a plurality of rows of transducers formed on a substrate. The closures are lapped for shortening the closures in a direction toward the transducers. An extent of the lapping is determined using an optical and/or a contact technique.
