Title: Akihiko Rokusaka: Innovator in Information Reproduction Technology

Introduction

Akihiko Rokusaka is a notable inventor based in Kodaira, Japan. He has made significant contributions to the field of information reproduction technology, particularly in the area of error detection and correction for recorded information.

Latest Patents

Rokusaka holds a patent for an "Apparatus for reproducing recorded information with error detection." This innovative apparatus reads information from the track surface of a CD-ROM disk, performs error detection and correction processing, and outputs the reproduced information. The device includes a control mechanism that switches the reproduction operation to a standard speed mode when a correction failure occurs in the quadruple speed mode. By reducing the signal read speed to one-fourth during retry processing, the apparatus improves the C/N ratio of the high-frequency signal RF by 6 dB, enhancing the correction capability for random errors.
