摘要： An optical disc apparatus capable of reducing looseness vibrations resulting from a gap between a sub-guide shaft and a bearing is provided. According to an optical disc apparatus in the present invention, both ends of the sub-guide shaft are supported by being sandwiched between a pair of support parts formed in a chassis and a pair of pressing members mounted on the chassis. The support part is formed by bending a protruding portion both protruding in an inward direction of a hole from an edge of the hole of the chassis and extending along the direction perpendicular to the sub-guide shaft.

摘要： Increases in the data transfer rates of optical disc drives have resulted in problems such as increases in optical disc vibrations due to higher rotation speeds or increases in heat generation due to increases in the output of motors for rotating the optical discs and in the output of laser diodes. To solve such problems, an optical pickup is provided with an air duct therein, and a space that is formed between the optical disc and a top case of a casing and that has negative pressure during rotation of the optical disc is connected to the air duct in the optical pickup via a tube, at least part of the tube being deformable. The optical pickup is cooled by the air flow through the air duct induced by pressure difference.
