Title: Wolfgang Goubau: Innovator in Magnetic Head Technology
Introduction
Wolfgang Goubau is a notable inventor based in Santa Cruz, CA (US). He has made significant contributions to the field of magnetic head technology, holding a total of 3 patents. His work has advanced the methods used in the fabrication and testing of magnetic recording heads.
Latest Patents
Goubau's latest patents include innovative methods that enhance the performance and reliability of magnetic heads. One of his patents describes a method for lapping gold pads in a liquid medium to work harden the surface of the pads. This method involves providing gold contact pads and lapping pads, which are placed in contact to create a contact interface. A liquid medium, preferably a particulate-free pH neutral liquid like water, is applied while moving the lapping pads relative to the gold contact pads. This process results in a gold pad with a work-hardened surface.
Another significant patent focuses on detecting magnetic pole defects in perpendicular recording heads at the wafer level. This method includes fabricating magnetic pole testing structures in the kerf area of the wafer substrate. By magnetically connecting the extending portions of the first and second magnetic poles, Goubau's method allows for an ISAT magnetic pole test to be conducted. This test enables the evaluation of the magnetic poles of the perpendicular magnetic head at the wafer level, enhancing the quality control process in manufacturing.
