Title: Innovations and Contributions of Toshiya Shiramatsu in Magnetic Head Technology

Introduction

Toshiya Shiramatsu, an esteemed inventor based in Kanagawa, Japan, holds an impressive portfolio of 28 patents. His innovative work primarily revolves around magnetic head technology, which plays a crucial role in the efficiency of data storage devices. His patents reflect a deep understanding of the complexities involved in the design and manufacturing of magnetic heads.

Latest Patents

One of Shiramatsu's latest inventions is a **magnetic head with a heating element between the read and write element** and a corresponding method of manufacturing it. In this embodiment, the magnetic head comprises a write element, a read element, and a strategically placed heating element. Upon application of power to the heating element, either the read or write element protrudes beyond the plane of the air-bearing surface (ABS), while the magnetically interacting side of the ABS may display a concave shape when power is not applied. Additionally, the invention enhances functionality during operation by allowing close proximity between the read or write elements and the magnetic disk, specifically through the heating element's activation.

Another notable patent covers **systems and methods for clearance monitoring in storage media**. This innovative method involves measuring head-disk clearance between a slider and a disk through an embedded contact sensor. By applying two different bias voltages to the sensor and measuring the corresponding resistances, the patent provides a robust mechanism to accurately determine the head-disk clearance based on resistance variations.
