路を具備してなるトラツキングサーボ装置。[Claims for Utility Model Registration] Tracking that causes a beam to follow a track based on a tracking error signal generated according to the amount of displacement between a track formed on a disk and a beam that is to follow the track. The servo device includes an amplifier circuit to which the tracking error signal is input and amplifies the tracking error signal so that a characteristic of the tracking error signal according to the amount of displacement between the track and the beam becomes a linear characteristic. Tracking servo device.
