Title: Kazuhiro Ichikawa: Innovator in Optical Disc Technology
Introduction
Kazuhiro Ichikawa is a prominent inventor based in Osaka, Japan. He has made significant contributions to the field of optical disc technology, holding a total of 3 patents. His work focuses on enhancing the efficiency and functionality of optical disc recording and reproduction methods.
Latest Patents
Ichikawa's latest patents include an optical disc recording device and an optical disc recording method. The optical disc apparatus he developed determines whether the recording medium is a DVD-RW or DVD+RW during data recording. If identified as such, the device reads maximum length information from a storage portion, which contains the maximum data length that can be recorded in one operation. The data to be recorded is then split into segments that adhere to this maximum length. Additionally, the device resets the base electric power for the semiconductor laser element with each recording operation.
Another notable patent is the optical disc device and optical disc reproduction method. This device is designed to reproduce optical discs and includes an optical pickup and a driver. The optical pickup emits a laser beam to obtain return light, while the driver generates a drive signal based on a high-frequency signal. The driver also differentiates the amplitude of the high-frequency signal used during the reproduction of the test region from that used in the data region, ensuring optimal performance.
