Title: Innovations of Yasushi Kobayashi
Introduction
Yasushi Kobayashi is a prominent inventor based in Osaka, Japan. He has made significant contributions to the field of optical information technology, holding a total of 15 patents. His work focuses on enhancing data recording and playback methods, which are crucial for the development of high-capacity optical disks.
Latest Patents
Kobayashi's latest patents include a recording state evaluation method, a recording compensation method, and an information recording/playback device. The recording mark is formed on a recording medium by a predetermined recording signal. A playback signal of the recording mark is obtained, and an expected value signal of the playback signal based on the recording signal is generated. Based on the amplitude error between the playback signal and the expected value signal, a deviation amount of a mark shape of the recording mark is calculated. This is done for each predetermined unit of the recording signal, allowing for the estimation of the mark shape of the recording mark formed on the recording medium. Furthermore, a correction amount is calculated for each predetermined unit of the recording signal, enabling the adjustment of the level of the recording signal.
Another notable patent involves an objective lens, optical head device, optical information device, and optical disk system. This objective lens is designed to accumulate more information in a large-capacity optical disk while enhancing the numerical aperture (NA). The lens is a single lens with a numerical aperture NA and a refractive index n, configured to satisfy specific conditions for optimal performance.
