Title: Innovations of Yoshihiko Maeda

Introduction

Yoshihiko Maeda is a prominent inventor based in Kanagawa, Japan. He has made significant contributions to the field of disk drive technology, holding a total of 5 patents. His work focuses on improving the performance and reliability of disk drives, which are essential components in various electronic devices.

Latest Patents

One of Maeda's latest patents is a method for measuring clearance change in disk drives. This innovative method involves reading a preliminarily written data string on a disk to obtain a first measured value corresponding to clearance. It also includes writing a new data string for deterioration checks and reading it to obtain a second measured value. The method determines the deterioration of the data string based on the difference between the two measured values. If the data string has not deteriorated, clearance change is measured using normal operations. Conversely, if deterioration is detected, a different operation is employed for measurement.

Another notable patent is related to head/disk contact determination in disk drives. This invention features a sensor element that detects contact between a head slider and a disk. It includes a head integrated circuit (IC) that amplifies the signal from the head slider and a controller IC that manages the head IC's operations. The identification section within the head IC determines the contact frequency using a timing control signal from the controller IC.
