Title: James Hammond Brannon: Innovator in Storage Device Technology

Introduction

James Hammond Brannon is a notable inventor based in Palo Alto, CA. He has made significant contributions to the field of storage device technology, holding a total of 13 patents. His work focuses on improving the functionality and reliability of storage devices, particularly through innovative methods of estimating flyheight in airbearing sliders.

Latest Patents

One of Brannon's latest patents is a method and apparatus for estimating the flyheight of an airbearing slider in a storage device. This invention addresses the challenges faced by sliders that float on an airbearing over rotating storage disks. The storage disk features a washboard-sequence with sections that have varying surface profiles. These profiles are designed to excite the airbearing resonance of the slider as the disk rotates. By measuring the maximum amplitude of flyheight modulation for each washboard-section, Brannon's method determines which section causes the largest modulation. This information is crucial for estimating the flyheight of the slider, allowing for timely actions to prevent catastrophic head crashes and extend the useful life of the storage device.

Career Highlights

Throughout his career, Brannon has worked with prominent companies in the technology sector. He has been associated with IBM and Hitachi Global Storage Technologies. His experience in these organizations has contributed to his expertise in storage device innovations.
