Title: Innovations of Reiichi Kurumisawa

Introduction

Reiichi Kurumisawa is a notable inventor based in Tokyo, Japan. He has made significant contributions to the field of magnetic recording technology. With a total of 3 patents to his name, his work has advanced the capabilities of magnetic recording devices.

Latest Patents

Kurumisawa's latest patents include a perpendicular magnetic recording head, a method of manufacturing the same, and a magnetic recording apparatus. This perpendicular magnetic recording head minimizes the possibility of unintentionally erasing recorded information during the recording process. The design features a pole layer with a main pole layer on the leading side and an auxiliary pole layer on the trailing side. This configuration ensures that even if some magnetic flux from the auxiliary pole layer is emitted directly from the air bearing surface, it does not easily generate an unnecessary perpendicular magnetic field. Consequently, the recorded information remains intact.

Another significant patent involves a thin film magnetic head and its manufacturing method. This invention assures recording characteristics by accurately determining throat height with high precision. A TH specifying layer is formed adjacent to a gap layer, and an auxiliary insulating layer is created to extend from a specific position while also being adjacent to the gap layer. This method allows for stable and accurate throat height determination, enhancing the performance of the magnetic head.
