Abstract:
A method of generating a 1-beam tracking error signal (TES), an optical pickup device, and an optical disc drive device adopting the method. A light-receiving element receives a single reflection beam and detects an alternating current (AC) component and a direct current (DC) component from each of areas formed on two sides of a data track. A servo unit generates a TES by adding and subtracting the AC component and the DC component.
