Embodiment Construction

[0032] 【Description of Disk Drive】

[0033] A rotating disk storage device according to a preferred embodiment of the present invention will now be described by taking a disk drive as an example. In this specification and in all drawings, the same parts are marked with the same reference numerals. figure 2 (A) and figure 2 (B) is a plan view showing the internal structure of the magnetic disk drive 10 . The magnetic disk drive 10 is depicted by a housing composed of a base 12 and a cover 18 . Chassis 12 includes a base plate 14 on which the major components of disk drive 10 are mounted. Base 12 also includes side walls 13 that provide a bonding surface between base 12 and cover 18 . The base 12 may be formed by pressing of cold rolled steel sheet or by die casting of aluminum. The cover 18 may be formed by stamping a thin sheet of aluminum or cold rolled steel. Inside the disc casing, the base 12 and the cover 18 are joined together by a gasket (not shown) to form a cl...

Abstract

A rotating disk storage device is provided with a charging filter capable of efficiently removing dust staying in the interior of the device. In one embodiment, a charging filter is disposed below a magnetic disk and on a bottom of a base. The charging filter has plural through holes by forming a fibrous electret filter medium in a pleat shape. The through holes are formed so as to face a flowing direction of air. Dust, which is moving together with the air flow, is polarized and is attracted to the charging filter. The charging filter can collect even very fine particles without causing such problems as clogging and pressure loss. The pleat portion, which forms the through holes, further exhibits an air flow uniforming effect.

Description

technical field [0001] This invention relates to dust collection filters housed in rotating disk storage devices such as disk drives and optical disk drives. In particular, the present invention relates to a rotating disk storage device having an electrostatic filter that electrostatically sucks dust suspended in an air flow generated by disk media rotation, and then separates the dust from the air and collects the dust. Background technique [0002] In a magnetic disk drive, which is a rotating disk storage device, recording density is increasing along with an increase in storage capacity and a decrease in size. Thus, the interval between the recording surface and the magnetic head becomes narrower and narrower. At the same time, it has become more important to deal with the problem of tiny dust particles adhering to the surface of the disk and thus causing head failure. Disk drives can be assembled in a clean room that maintains a clean air environment, but it is difficu...
