摘要： An optical disk device and recording method of recording data on an optical disk by driving a laser light source with a driving current superimposed with a high-frequency current. The device and method includes a controller for disabling tracking servo and establishing conditions for reproducing a signal from a predetermined region of the optical disk, for generating a tracking error signal by superimposing the high-frequency current varied in amplitude on the driving current for the laser light source, for determining an amplitude of the high-frequency current that provides an optimum quality of the generated tracking error signal, and for recording data on the optical disk by applying the driving current for the laser light source superimposed with the high-frequency current of the determined amplitude.

摘要： The present invention provides a single information recording and reproducing apparatus that is used to record data to multiple disks that are to be recorded on using different wavelengths. More specifically, the present invention provides an apparatus that accurately discriminates disk types while preventing disk damage and accidental recording of data during the disk type discrimination operation. The disk type is determined using the intensity of light reflected from the disk. Information is encoded using an encoder corresponding to the disk type. The resulting signal is used to drive a laser corresponding to the disk type, and information is recorded.
