MAGNETIC WRITE HEAD MANUFACTURED BY AN ENHANCED DAMASCENE PROCESS PRODUCING A TAPERED WRITE POLE WITH A NON-MAGNETIC SPACER AND NON-MAGNETIC BUMP

摘要

A magnetic write head having a tapered trailing edge and having a magnetic layer formed over a trailing edge of the write pole at a location recessed from the ABS, the magnetic layer being separated from the trailing edge of the write pole by a thin non-magnetic layer. The thin non-magnetic layer is preferably sufficiently thin that the magnetic layer can function as a portion of the write pole in a region removed from the ABS. A trailing magnetic shield is formed over the write pole and is separated from the write pole by a non-magnetic trailing gap layer. A non-magnetic spacer layer can be formed over the magnetic layer to provide additional separation between the magnetic layer and the trailing magnetic shield.
