Title: Innovations of Peter R Ivett in Magnetic Recording Technology
Introduction
Peter R Ivett is a notable inventor based in Rochester, MN (US). He has made significant contributions to the field of magnetic recording technology, holding a total of 2 patents. His work primarily focuses on enhancing the properties and performance of magnetic recording media.
Latest Patents
Peter R Ivett's latest patents include innovations in magnetic recording mediums. One of his patents describes a magnetic recording medium having a cobalt-platinum-chromium alloy. This invention involves controlling the magnetic properties of a cobalt-based hard magnetic alloy by providing a thin, sputtered underlayer of a nonmagnetic, binary chromium-tungsten alloy. The composition of this underlayer is preferably Cr.sub.88 W.sub.12, which supports the deposition of the thin film magnetic recording layer.
Another significant patent by Ivett is related to thin film magnetic media. This invention outlines a fabrication method and structure for cobalt alloy thin film magnetic recording media. It utilizes an underlayer of sputter deposited chromium, which has a thickness of 50 to 200 angstroms. This underlayer presents the (100) plane of the chromium atoms at the surface, allowing for optimal deposition of the cobalt alloy magnetic thin film layer. The cobalt alloy is sputtered onto the chromium underlayer and is designed to have its (110) plane parallel to the media surface, optimizing horizontal recording density.
