Patent number: 7929246Abstract: Embodiments of the present invention prevent a magnetic disk drive from increasing in size and in manufacturing cost and reduces a positioning error of a magnetic head. An embodiment of a magnetic disk drive in accordance with the present invention includes: a disk-shaped magnetic disk that is rotated and driven; a magnetic head that reads and writes information to and from the magnetic disk, an arm that supports and moves the magnetic head; a spoiler that is close to a disk surface and extends in a radial direction of the disk; and a cabinet that houses these parts. The spoiler is disposed closer to an upstream side in a rotational direction of the disk than the arm and has a flow rate suppressing clearance positioned in a central portion in a peripheral direction of the spoiler, opened to both sides in an axial direction, and formed in a shape elongated in a radial direction of the disk.Type: GrantFiled: June 4, 2007Date of Patent: April 19, 2011Assignee: Hitachi Global Storage Technologies Netherlands B.V.Inventors: Keiichi Takemori, Masato Ikegawa, Hiroshi Mukai, Hiroyuki Ishii, Yukinobu Abe

Patent number: 7869159Abstract: A sickle-shaped disk drive spoiler for reducing turbulence of airflow in a hard disk drive is provided. The sickle-shaped spoiler includes a body portion for directing airflow generated by a rotating disk, the rotating disk comprising an inner diameter and an outer diameter and wherein the body portion of the spoiler directs airflow away from the outer diameter of the disk and wherein the body portion is curved to substantially mirror the outer diameter of the disk. The sickle-shaped spoiler also includes a first end portion for gradually directing airflow away from the body portion and towards the inner diameter and a second end portion for gradually directing airflow towards the body portion and towards the inner diameter.Type: GrantFiled: June 28, 2007Date of Patent: January 11, 2011Assignee: Hitachi Global Storage Technologies, Netherlands, B.V.Inventors: Yukinobu Abe, Andre S.

Patent number: 7614062Abstract: 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.Type: GrantFiled: September 28, 2006Date of Patent: November 3, 2009Assignees: Hitachi, Ltd., Hitachi-LG Data Storage, IncInventors: Yukinobu Abe, Nobuyuki Isoshima, Ikuo Nishida
