Title: Keiichi Shinoda: Innovator in Lapping Technology

Introduction

Keiichi Shinoda is a notable inventor based in Hamamatsu, Japan. He has made significant contributions to the field of lapping technology, particularly in the production of one-side curved surfaces. His innovative methods have implications for improving the reliability of data read/write processes.

Latest Patents

Shinoda holds a patent for a method of lapping that produces a one-side curved surface. This method involves lapping both an ABS and a back surface of a slider to achieve balanced compressive stresses. The process results in unbalanced stresses that make the ABS flat while warping it. The slider deforms by changing the back surface into a convex shape, while the ABS remains flat. Following this, a one-surface lapping of the back surface is performed to reduce compressive stresses and create a flat surface, further warping the back surface. This innovative approach allows for the formation of a positive crown on the ABS, enhancing the reliability of data read/write operations.
