Abstract
A tilt adjusting device for an optical pickup head (OPU) is fixed on a chassis of an optical drive. The device includes a first screw and a secondary guide rail. The secondary guide rail includes a guide rail part, a base part, an extension part, and an elastic element. The guide rail part is embedded into a rail notch of the OPU and the extension part has a first end and a second end connected with the base part and the guide rail part. A first compressible space is defined between the base part, the elastic element and the chassis. The first screw is penetrated through the base part and the first compressible space and screwed in the chassis. By changing a screwed depth of the first screw in a screw hole, an altitude of the guide rail part is correspondingly adjusted.
