Latest Patents
Ferraguto's latest patents focus on a process for producing a pole-trimmed writer in a magnetoresistive environment. This innovative design allows for the creation of a pole-trimmed writer for an MR read/write data transducer without significant re-deposition of Al.sub.2 O.sub.3 or NiFe on the sides of the writer poles. The disclosed process provides an upper pole that is processed to project a pair of relatively thin, laterally extending lower flanges. This is achieved prior to using the upper pole as a mask for subsequent ion milling of the lower pole or shared shield. The preferred embodiment of this process involves the deposition of a single copper (Cu) or dual Al.sub.2 O.sub.3 and chromium (Cr) overlayers formed on the upper pole seed layer, followed by the top pole formation and selective removal of a predetermined amount of the underlying portions of the gap material before further processing of the read/write head.
