ABSTRACT:
For automatic adjustment of tracking balance, a microprocessor controls a servo control unit to adjust a tracking balance signal value for the optical disc reproduction to be a mid-value between a tracking balance signal value (hereafter referred to as first tracking balance signal value) to make a tracking error balance value 0% and a tracking balance signal value (hereafter referred to as second tracking balance signal value) to minimize jitter when the first tracking balance signal value is different from the second tracking balance signal value. This makes it possible to perform balanced tracking control with a good balance between tracking performance and jitter performance.
