Title: Innovations by Tatsuro Sasamoto
Introduction
Tatsuro Sasamoto is a prominent inventor based in Kawasaki, Japan. He has made significant contributions to the field of servo pattern technology, holding a total of 17 patents. His work focuses on improving the efficiency and accuracy of disk media production.
Latest Patents
Sasamoto's latest patents include a servo pattern writing apparatus, a servo pattern writing method, a servo pattern reading apparatus, and a servo pattern reading method. These innovations provide a technique capable of eliminating the need to create data for compensating the displacement of a servo pattern during the writing process. This advancement significantly reduces the production time of disk media. The servo pattern writing apparatus utilizes a write head to write a servo pattern on a recording medium according to an amplitude method. It features a position sensor that detects the displacement amount of the write head in relation to its reference position in the track crossing direction. Additionally, a delay amount adjustment circuit writes a servo pattern corresponding to a servo pattern write phase amount, compensating for the detected displacement during demodulation.
