Latest Patents
Gohshi Jin's latest patents include an optical disk device and an optical disk recording method. The optical disk device and recording method involve recording data on an optical disk by driving a laser light source with a driving current superimposed with a high-frequency current. This invention features a controller that disables tracking servo and establishes conditions for reproducing a signal from a predetermined region of the optical disk. It generates a tracking error signal by superimposing a high-frequency current varied in amplitude on the driving current for the laser light source. The controller also determines the amplitude of the high-frequency current that provides optimum quality for the generated tracking error signal, allowing for efficient data recording on the optical disk.
Another significant patent is the optical disc apparatus and defocus correcting method. This apparatus changes the bias of a focusing error signal according to the recording power at a timing corresponding to a predetermined address position before starting the recording. It also causes a defocus of an opposite polarity to offset the defocus that occurs at the start of the recording, enhancing the reliability of the recording process.
