Abstract

A disk drive for information storage having at least one disk for recording data and a head actuator which includes a read/write head for reading and writing data to the disk. The disk drive includes an accessory member, such as a filter or spoiler, which is formed with an attaching part. A cabinet is used for housing therein the disk, head actuator, and accessory member. The cabinet is divided into a first cabinet part and a second cabinet part, such that the attaching part of the accessory member is sandwiched or interposed between the first and second cabinet parts and located in position inside the cabinet when the two cabinet parts are joined together. Thus, the accessory member can be attachably positioned to the disk drive inside the cabinet without using screws or other time-consuming and costly assembly techniques.

Claims

1. A method of assembling a disk drive, the method comprising:

(a) providing a plurality of disks;

(b) providing a head actuator having a plurality of parallel head arms;

(c) providing an accessory member having an attaching part and a fitting part;

(d) providing a cabinet divided into a cover and a base with the cover and base having walls for matingly being joined together, the base having a protruding type pin at the inside thereof and adjacent to a surface of the base receiving the cover;

(e) mounting the disks and head actuator into the base;

(f) engaging the fitting part of the accessory member to the pin of the cabinet base;

(g) positioning the attaching part of the accessory member on the surface of the base receiving the cover by rotating the accessory member around the pin; and

(h) joining the cover and base together so that the attaching part of accessory member is interposed between the mating walls of the cover and base.

2. The method of claim 1, wherein step (c) comprises providing a filter integrating spoiler with a plurality of parallel fins as the accessory member, and step (g) further comprises positioning the fins of the spoiler in between the disks by rotating the filter integrating spoiler around the pin until the attaching part of the filter integrating spoiler engages with the surface of the base receiving the cover.

3. A method of assembling a disk drive, the method comprising:

(a) providing a plurality of disks;

(b) providing a head actuator having a plurality of parallel head arms;

(c) providing an accessory member having an attaching part and a fitting part;

(d) providing a cabinet divided into a cover and a base with the cover and base having walls for matingly being joined together;

(e) providing a protruding type pin;

(f) mounting the protruded type in at the inside and adjacent to a surface of the base receiving the cover;

(g) mounting the disks and the head actuator into the base;

(h) engaging the fitting part of the accessory member to the pin;

(i) positioning the attaching part of the accessory member on the surface of the base receiving the cover by rotating the accessory member around the pin; and

(j) joining the cover and base together so that the attaching part of accessory member is interposed between the mating walls of the cover and base.

4. The method of claim 3, wherein step (c) comprises providing a filter integrating spoiler with a plurality of parallel fins as the accessory member, and step (i) further comprises positioning the fins of the spoiler in between the disks by rotating the filter integrating spoiler around the pin until the attaching part of the filter integrating spoiler engages with the surface of the base receiving the cover.

5. The method of claim 3, wherein step (f) comprises forming a hole in the base adjacent to the accessory attaching position of the base and inserting the protruded type pin into the hole.

6. The method of claim 3, wherein step (f) comprises integrally forming the pin with the base.
