Abstract

A disk drive includes a housing, a disk recording medium disposed in the housing, and a plurality of filters disposed along a flow channel formed in the housing and overlapped with each other. Each of the filters including an outer member formed of an electrostatic woven fabric and electrostatic non-woven fibers contained in an enclosed space formed by the outer member.

Claims

1. A disk drive, comprising:

a housing;

a disk recording medium disposed in the housing; and

a plurality of filters disposed along a flow channel formed in the housing and overlapped with each other, each of the filters including an outer member formed of an electrostatic woven fabric and electrostatic non-woven fibers contained in an enclosed space formed by the outer member.

2. The disk drive according to claim 1, wherein

each of the filters is in contact with an adjacent filter at a center region thereof.

3. The disk drive according to claim 2, wherein

each of the filters is not in contact with the adjacent filter at non-center regions thereof.

4. The disk drive according to claim 1, wherein

each of the filters includes a first region and a second region that has a thickness smaller than the first region, and is in contact with an adjacent filter at the first region thereof.

5. The disk drive according to claim 4, wherein

each of the filters is not in contact with the adjacent filter at the second region thereof.

6. The disk drive according to claim 1, wherein

the outer member of each of the filters is formed of two members bonded to each other at peripheral regions thereof, such that the enclosed space is formed.

7. A disk drive, comprising:

a housing;

a disk recording medium disposed in the housing; and

a filter disposed along a flow channel formed in the housing, the filter including a plurality of portions overlapped with each other by being folded, each of the portions of the filter including an outer member formed of an electrostatic woven fabric and electrostatic non-woven fibers contained in an enclosed space formed by the outer member.

8. The disk drive according to claim 7, wherein

each of the portions of the filter is in contact with an adjacent portion at a center region thereof.

9. The disk drive according to claim 8, wherein

each of the portions of the filter is not in contact with the adjacent filter at a non-center region thereof.

10. The disk drive according to claim 7, wherein

each of the portions of the filter includes a first region and a second region that has a thickness smaller than the first region, and is in contact with an adjacent filter at the first region thereof.

11. The disk drive according to claim 10, wherein

each of the portions of the filter is not in contact with the adjacent filter at the second region thereof.

12. The disk drive according to claim 7, wherein

the outer members of the filter are integrally formed, and include two members bonded to each other at a peripheral region of each of the portions, such that the enclosed spaces are formed.

13. The disk drive according to claim 7, wherein

the filter is folded along a perforation formed therein.

14. The disk drive according to claim 7, wherein

the filter is disposed in the housing, such that a folded end thereof faces a bottom of the housing.

15. The disk drive according to claim 7, wherein

the filter includes first, second, and third portions arranged along a line in this order and formed from an integral unit,

a first surface of the second portion is in contact with the first portion by folding the integral unit at a boundary between the first and second portions, and

a second surface of the second portion that is opposite to the first surface is in contact with the third portion by folding the integral unit at a boundary between the second and third portions.

16. A filter for a disk drive, comprising:

a first outer member formed of an electrostatic woven fabric;

a second outer member formed of an electrostatic woven fabric, the first and second outer members being bonded with each other such that a plurality of compartments is formed therebetween; and

electrostatic non-woven fibers disposed in each of the compartments.

17. The filter according to claim 16, wherein

a perforation is formed through the first and second outer members between adjacent two of the compartments.

18. The filter according to claim 16, wherein

the compartments include three compartments arranged along a line.
