Title: Tetsuya Tsuji: Innovator in Optical Information Storage
Introduction
Tetsuya Tsuji is a prominent inventor based in Kawasaki, Japan. He has made significant contributions to the field of optical information storage, holding 2 patents that showcase his innovative approach to data processing and storage technologies.
Latest Patents
Tsuji's latest patents include an optical information storing device and an optical disk apparatus. The optical information storing device aims to provide an inexpensive solution that reduces cross talk. It features a cyclic data output circuit that outputs cyclic data with values repeated every 5 bytes. Additionally, it includes an EXOR circuit that calculates the exclusive-OR of recording data input via a buffer and the cyclic data, which is then sent to an RLL modulation circuit for recording. The optical disk apparatus incorporates a constant linear velocity control (CLV control) and a constant angular velocity control (CAV control) to manage the spindle motor's operation. This system ensures a constant linear velocity in the track circumferential direction and a constant rotation of the medium, adapting to changes in the radial position of the medium based on detection results.
