Laser energy compensation method for disk drives, involves acquiring and writing best light emission variable without any disturbance factor into laser light emission control system of disk drive
Laser energy compensation method for disk drives, involves acquiring and writing best light emission variable without any disturbance factor into laser light emission control system of disk drive
Different light emission variables are input into a laser element and the emitted light signals are read out. An initial stage sampling is performed with respect to the reflected signal and a best light emission variable without any disturbance factor is acquired and written into laser light emission control system of a disk drive.
