  • Patent number: 7640558
    Abstract: 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.

  • Patent number: 7614062
    Abstract: This invention provides an optical disk device in which heat generated from an optical head and circuit board is dissipated without introduction of outside air or use of a fan. A through portion is provided in part of the mechanical block or outside of the portion on which a tray is projected for carrying a disk for reproduction or write, such that it extends from a disk side portion with respect to the tray to a portion opposing the disk with respect to the tray, in order to introduce air flow generated by disk rotation to an optical head and circuit board and dissipate heat generated at the time of recording or reproduction.
