Title: Innovations by Hiroshi Mitsuda: A Leader in Optical Disc Technology
Introduction
Hiroshi Mitsuda, an esteemed inventor based in Osaka, Japan, holds an impressive portfolio of six patents. His contributions to the field of optical disc technology have significantly advanced recording and reproducing methods.
Latest Patents
Mitsuda's recent innovations include an optical disk recording device and an optical disk recording method. The optical disk recording device optimizes recording power by utilizing the correct β value, determining whether the average of modulation values between the 2nd to 4th AUNs is less than or equal to 65% of the average of modulation values between the 5th to 7th AUNs. Should this condition remain unfulfilled, gradual emission is conducted, followed by measuring the β value, leading to the assessment of several requirements, including the critical comparison of recording areas based on output levels. These intricacies ensure more precise and effective optical disk recording.
Additionally, the optical disc reproducing apparatus developed by Mitsuda focuses on enhancing data retrieval. It features two parallel light-receiving regions where the reflected light from the optical disk is converted into electric signals. The system calculates the light-receiving ratio from these signals and determines if the absolute value exceeds a predetermined threshold. Should this condition hold true, a corrective movement of the objective lens takes place, ensuring enhanced accuracy in data reproduction.
