Title: Kohji Takasaki: Innovator in Disk Drive Technology
Introduction
Kohji Takasaki is a prominent inventor based in Kanagawa, Japan. He has made significant contributions to the field of disk drive technology, holding a total of 7 patents. His work focuses on improving the performance and reliability of hard disk drives (HDDs) through innovative servo control methods.
Latest Patents
One of his latest patents is for a disk drive device and servo control method that enhances servo control in response to detected vibrations. This invention allows an HDD to switch between a correction servo mode, which performs vibration correction during head positioning, and a normal servo mode, which does not. The HDD determines servo positioning accuracy based on measured positional error signals and compares the accuracy between the two modes to select the one with higher precision.
Another notable patent involves methods for writing patterns on disks and following tracks. This invention efficiently performs servo correction to prevent the propagation of position errors in self servo write (SSW) processes. By correcting target positions in respective tracks using impulse responses of the servo system, the invention effectively mitigates position errors during the writing process.
