Abstract: An optical disk drive includes a body, a tray, a first fastening structure, and a second fastening structure. The body has an opening. The tray is coupled to the body and movable at the opening. The first fastening structure is disposed at the body, and the second fastening structure is disposed at the tray. When the tray is situated in the body, the first fastening structure and second fastening structure are correspondingly fastened to each other to restrict the displacement of the tray along the vertical direction in the body.

Abstract: A micro-adjustment apparatus for the spindle motor installation angle in an optical disk player is provided. The optical disk player includes a traverse, and the traverse includes a pickup, a first guide rail, and a framework. The pickup includes a light source for supplying a light beam, and the first guide rail guides the pickup during data reproduction. A spin surface is defined while the spindle is spinning. The micro-adjustment apparatus includes a supporting plate, a pivotal device, a first adjustable pivotal device, and a second adjustable pivotal device. The supporting plate supports the spindle motor and is adjustably coupled to the framework. The pivotal device is disposed at a first predetermined location on the supporting plate and contacts the first guide rail. The first adjustable pivotal device is disposed at a second predetermined location on the supporting plate for adjusting an elevation angle of the supporting plate such that the light beam is substantially vertical to the spin surface.
