Title: Tomoo Iizumi: Innovator in Magnetic Disk Drive Technology
Introduction
Tomoo Iizumi is a notable inventor based in Furukawa, Japan. He has made significant contributions to the field of magnetic disk drive technology, holding a total of 4 patents. His innovative methods have advanced the efficiency and accuracy of data retrieval in disk drives.
Latest Patents
One of Iizumi's latest patents is a method for detecting a zero track in a magnetic disk drive device. This invention involves a rotatable disk that contains data tracks and guard band tracks. The data is recorded on the data tracks in a reversed magnetization form, while the guard band track remains unrecorded. The magnetic head detects data from the data track, and the position where the first data is detected is recognized as the zero track. This zero track is electronically detectable and guides the magnetic head's data-seeking process.
Another significant patent by Iizumi is a method for recorrecting the head position in a disk drive. This method is designed for a disk driving device that includes a zero track restoring arrangement for electrically detecting the zero track position. It also features a track counter that indicates the magnetic head's track position. The method ensures that the head's position is accurately re-corrected when the track number is '0' or '1', thereby enhancing the reliability of the disk drive.
