Title: Takuya Nagata: Innovator in Optical Disk Technology

Introduction

Takuya Nagata is a prominent inventor based in Hoya, Japan. He has made significant contributions to the field of optical disk technology, holding a total of 3 patents. His innovative work focuses on enhancing the functionality and efficiency of optical disk apparatuses.

Latest Patents

One of Nagata's latest patents is an optical disk storage system that provides pull-in of focus servo and pull-in. This miniaturized optical disk apparatus performs a pull-in of a focus servo and a pull-in of a tracking servo without the need for a position detector to detect the optical head. If the optical head is positioned at a non-reflection film area, preventing the focus servo from functioning, the optical head is moved, and the focus servo is attempted again. This process is repeated until the focus servo is successfully achieved. Additionally, if the optical head is located at a non-track area, the optical disk is moved to a track area, and the tracking servo is performed. This method ensures that the tracking servo is stably executed only when the optical head is correctly positioned over the track area. This invention is applicable to optical disk apparatuses that utilize a 3.5-inch optical disk.

Another notable patent is a method for rewriting defect management areas on an optical disk according to an ECMA standard. This method involves deleting old data recorded in the respective defect management areas and sequentially writing new data in those areas.
