摘要
A servo system of an optical storage device and related method for generating a servo signal. The servo system includes a pick-up head for detecting signals reflected from an optical disc to generate a plurality of detecting signals; a gain stage coupled to the pick-up head for determining a gain value according to an output of the pick-up head and for adjusting the magnitude of the detecting signals according to the gain value; and a servo signal generator coupled to the gain stage for generating the servo signal according to the adjusted detecting signals outputted from the gain stage.
