Title: James Weispfenning: Innovator in Disk Drive Technology
Introduction
James Weispfenning is a notable inventor based in Rochester, MN (US). He has made significant contributions to the field of disk drive technology, particularly in enhancing the reliability of magneto-resistive heads.
Latest Patents
Weispfenning holds a patent for a disk drive that incorporates thermal asperity protection by reducing the electrical bias supplied to a magneto-resistive head. This innovative design addresses the issue of damage caused by thermal asperities, which can occur when the magneto-resistive head contacts an asperity on the disk surface. The patent outlines a system where a bias generator creates an electrical bias for the head, and a thermal asperity detector identifies any thermal asperity components in the read signal. Upon detection, the electrical bias is reduced temporarily, thereby safeguarding the magneto-resistive head from potential damage.
