Title: Kazunari Tsuchimoto: Innovator in Disk Drive Technology
Introduction
Kazunari Tsuchimoto is a prominent inventor based in Kanagawa, Japan. He has made significant contributions to the field of disk drive technology, holding a total of 8 patents. His work focuses on improving the capacity and performance of disk drive devices, which are essential in modern computing.
Latest Patents
One of Tsuchimoto's latest patents is a disk drive device and method for determining the data track format of the disk drive device. This invention enhances the capacity and performance of disk drives by setting a data track pitch for each recording surface and dividing the recording surfaces into bands. The hard disk drive (HDD) sequentially moves a head to an adjacent data track within a band, performing a head switch at the band end during data access. The number of data tracks in each band is variable, allowing for optimization based on the radial position of the band end. This innovation helps to suppress increases in process time due to head switches, even when recording surfaces have different variation rates of data track pitch.
Another notable patent addresses the adjacent track interference problem by introducing an alternate cylinder table. This invention prevents data loss caused by frequent writing onto adjacent data tracks. An alternate zone is formed by prohibiting the usage of every other data track, allowing for the separation of frequently updated data from less frequently updated data. This design minimizes data loss due to leakage fluxes, ensuring more reliable data storage.
