Abstract:
1. A method for adjusting an optical pick-up of an optical disc driver, said optical pick-up including a lens, said optical disc driver including a turntable for supporting and driving a disc, and a first and a second guiding shaft for guiding said optical pick-up, said first guiding shaft including a first inner end adjacent to said turntable and a first outer end distant away from said turntable, said second guiding shaft including a second inner end adjacent to said turntable and a second outer end distant away from said turntable, said method comprising the steps of: (1.1) moving said optical pick-up to close said first outer end and said second outer end; (1.2) providing a light impinging on said disc such that a first reflection light is reflected from said disc, said light penetrating through said disc and impinging on said lens such that a second reflection light is reflected from said lens; (1.3) driving said disc by using said turntable such that said first reflected light is projected into a first trace and said second reflected light is projected into a second trace, said first trace defining a center and said second trace defining a center; (1.4) adjusting said first outer end and said second outer end to make said center of said first trace to substantially coincide with said center of said second trace, wherein, after said adjustment step, said first inner end, said first outer end and said second outer end defining a plane; and (1.5) adjusting said second inner end such that said second inner end is substantially on said plane.
