Title: Yoshiaki Uji: Innovator in Disk Drive Technology
Introduction
Yoshiaki Uji is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of disk drive technology, holding a total of 3 patents. His work focuses on improving the performance and reliability of disk drives, which are essential components in modern computing.
Latest Patents
One of Uji's latest patents is titled "Disk drive and control method thereof." This invention addresses the issue of errors caused by the aged deterioration of a heater that adjusts the clearance between a head and a disk. The thermal fly height control (TFC) controller measures the resistance value of the heater at predetermined intervals. If the resistance value falls within a specified range, the process concludes without further action. However, if the value deviates from the range, the TFC controller initiates error handling procedures, notifying the host of the detected resistance failure.
Another notable patent is "Disk drive device, altitude determination method therefore and method for determining characteristic of head element portion." This invention allows for precise altitude calculations based on read-out signals from a head slider. The hard disk controller/multiprocessing unit (HDC/MPU) identifies any instability in the head element portion and adjusts the clearance accordingly. By analyzing signals of varying frequencies, the HDC/MPU can accurately calculate the altitude, ensuring optimal performance.
