Introduction

Yohichi Kusagaya is a notable inventor based in Mishima, Japan. He has made significant contributions to the field of magnetic disk technology. His innovative approach has led to the development of a unique patent that enhances the functionality of magnetic disk apparatuses.

Latest Patents

Kusagaya holds a patent for a "Magnetic disk apparatus and servo signal recording method." This invention allows for the generation of a reference clock signal without the need for an external reference. By writing a clock track only once using the head of the magnetic disk apparatus, even with a read/write element separation type head, the device can effectively measure the total number of clock bits in one revolution. The time interval between servo sectors is determined by dividing the total number of clock bits measured by the number of servo sectors. This innovative method ensures that the servo sectors are recorded at the determined intervals, utilizing the clock bits produced by the playback of the clock track.
