光盘装置以及光盘记录方法
摘要：
本发明提供一种光盘装置以及光盘记录方法。与光盘、装置的性能偏差相应地在短时内调整记录时重叠在激光驱动电流中的高频电流的振幅，实现记录时的伺服动作的稳定化。在调整向光盘(1)记录数据时重叠在激光光源(11)的驱动电流中高频电流时，控制器(5)设为脱离跟踪伺服而从光盘的规定的区域再生信号的状态。对于光拾取器(3)在激光光源的驱动电流上重叠改变振幅后的高频电流(HF)并通过信号处理电路(4)来取得跟踪错误(TE)信号。决定所取得的跟踪错误信号的质量(振幅的变动量ΔTE)成为最优的高频电流的振幅，并设定为记录时的高频电流的振幅。
摘要（英）：

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.
