Latest Patents

Takayuki Ono holds 1 patent for a process aimed at producing a substrate member for magnetic recording discs. This process enhances the surface state by eliminating defects such as micropores and strain caused by machining. The method involves forming a glass coating layer on an alumina-based ceramic substrate, which contains micropores of 5 µm or less and has a relative theoretical density of 90% or above. The glass coating layer undergoes hot isostatic pressing treatment, followed by mechanochemical polishing to achieve a layer thickness ranging from 3 µm to 200 µm, resulting in a surface free from micropores and strain. The glass coating can be applied through glazing or vapor deposition techniques like sputtering.
