Abstract

There is provided a base plate for a hard disk drive including: a disk accommodating part on which a disk having data stored therein is disposed; a head seating part formed to be lower than a position of the disk accommodating part and including a head driver disposed thereon providing driving force to a read-write head reading the data stored on the disk; a filter seated on the disk accommodating part and collecting foreign objects from air flowing during rotation of the disk; and a filter fixing part formed by punching a portion of the disk accommodating part and vertically raising the portion of the disk accommodating part, and fixing the filter.

Claims

1. A base plate for a hard disk drive, comprising:

a disk accommodating part including a disk disposed thereon having data stored therein;

a head seating part formed to be lower than a position of the disk accommodating part and including a head driver disposed thereon providing driving force to a read-write head reading the data stored on the disk;

a filter seated on the disk accommodating part and collecting foreign objects from air flowing during rotation of the disk; and

a filter fixing part formed by punching a portion of the disk accommodating part and vertically raising the portion of the disk accommodating part, and fixing the filter.

2. The base plate for a hard disk drive of claim 1, wherein the disk accommodating part includes a seating groove formed in a predetermined position thereof, on which the filter is fixedly seated.

3. The base plate for a hard disk drive of claim 1, further comprising a side wall part formed outside of the disk accommodating part to enclose an outer peripheral surface of the disk.

4. The base plate for a hard disk drive of claim 3, wherein the side wall part includes a groove formed therein, and one side of the filter is seated in the groove.

5. The base plate for a hard disk drive of claim 1, further comprising a sealing member sealing a punched portion of the disk accommodating part.

9. A hard disk drive, comprising:

the base plate for a hard disk drive of claim 1;

a spindle motor coupled to the base plate for a hard disk drive to rotate a disk;

a read-write head reading data from and writing data to the disk; and

a head driver moving the read-write head to a predetermined position on the disk.

6. A base plate for a hard disk drive, comprising:

a disk accommodating part including a disk disposed thereon having data stored therein;

a head seating part formed to be lower than a position of the disk accommodating part and including a head driver disposed thereon providing driving force to a read-write head reading the data stored on the disk;

a filter seated on the disk accommodating part and collecting foreign objects from air flowing during rotation of the disk; and

a filter fixing protrusion formed by exerting pressure on a bottom surface of the disk accommodating part in a predetermined position to allow the predetermined position to protrude, and fixing the filter.

7. The base plate for a hard disk drive of claim 6, further comprising a side wall part formed outside of the disk accommodating part to enclose an outer peripheral surface of the disk.

8. The base plate for a hard disk drive of claim 7, wherein the side wall part includes a groove formed therein, and one side of the filter is seated in the groove.
