With a total of 3 patents to his name, Suda's work has had a considerable impact on the efficiency and reliability of disk drive technologies.
Latest Patents
One of Suda's latest patents is focused on error recovery in units using GMR sensors. This invention describes a method and apparatus for recovering from operational errors that arise in information recording and reproducing units utilizing a head equipped with a GMR sensor. The process involves executing a first error recovery procedure, followed by a GMR evaluation procedure to assess the sensor's performance when the initial recovery fails. A resetting pulse is then applied to the GMR sensor based on the evaluation results.
Another significant patent by Suda pertains to a disk drive apparatus and a read error recovery method. This invention addresses the issue of thermal asperities on disk surfaces. It details a method for detecting projections on the recording surfaces when a signal transducer head makes contact. The invention allows for adjustments in the flying height of the signal transducer head, either by altering the disk rotation speed or by heating a suspension with a bimetal element. This innovative approach helps to break the projection, thereby preventing subsequent errors caused by thermal asperities.
