Title: **Innovative Contributions of Jeffrey G. Greiman in Magnetic Head Technology**
Introduction
Jeffrey G. Greiman, an accomplished inventor based in Worcester, MA, has made significant strides in the field of magnetic recording technology. With a total of two patents, Greiman's innovations focus on enhancing the production processes of magnetic head poles, thereby improving their performance and functionality in information storage devices.
Latest Patents
Greiman's latest patents include a groundbreaking process titled "Process for producing magnetic head poles utilizing sputtered materials and a recording head made thereby." This invention details a method where a combination of wet and dry etching steps are utilized strategically to create an undercut in the high magnetic moment materials beneath a photoresist area defining the pole. This technique ensures that any re-deposited material on the pole during dry etching remains weakly linked, allowing for efficient removal using a stream of gaseous particles. The materials involved in this process include cobalt-zirconium-tantalum (CoZrTa), iron-aluminum-nitride (FeAlN), iron-tantalum-nitride (FeTaN), and iron-nitride (FeN). Such innovations streamline the manufacturing process and enhance the reliability of magnetic recording heads.
