Abstract:
1. A system for supplying a driving voltage to move an optical pickup unit to a predetermined position, comprising: a command interactive unit for receiving commands for moving the optical pickup unit, the commands comprising a power-on discrimination command for discriminating a type of an optical disc when an optical disc drive is powered on and begins initialization with the optical disc already pre-loaded therein, and a disc-load discrimination command for discriminating the type of the optical disc when the optical disc is loaded in from outside of the optical disc drive after powering on; a storage unit for storing instructions, the instructions comprising a move-outwards instruction for instructing the optical pickup unit to move toward an outermost position, a move-inwards instruction for instructing the optical pickup unit to move toward an innermost position, and a move discriminate-position instruction for instructing the optical pickup unit to move from the innermost position to the predetermined position; an output unit constructed and arranged for outputting the instructions; and a drive module coupled to the output unit for supplying the driving voltage to sequentially move the optical pickup unit toward the outermost position, then to the innermost position, and finally from the innermost position to the predetermined position based on the instructions in responding to one of the power-on discrimination command and the disc-load discrimination command.
