Embodiment Construction

[0015]FIGS. 2A-2C illustrate an embodiment of the present invention as a method of manufacturing a disk drive. FIG. 2A shows at least one disk 2 is installed into a base 9, and a media cover 20 is coupled to the base 9, wherein the media cover 20 covers at least a portion of the disk 2 (FIG. 2B). FIGS. 2B and 2C shows how after installing the media cover 20, a head coupled 6 to an actuator arm 8 and a voice coil motor for rotating the actuator arm 8 about a pivot 10 are installed into the base 9. The media cover 20 is then removed and an HDA cover 11 is coupled to the base to form a head disk assembly (HDA) as shown in FIG. 3.

[0016]The voice coil motor may comprise any suitable components, but typically includes a voice coil 12 coupled to the base of the actuator arm 8 and a yoke 14. In the embodiment of FIG. 2A, the yoke 14 comprises a suitable flux conductor (e.g., metal) bent into an arc shape and comprising one or more magnets (not shown). In other embodiments, the yoke 14 may c...

Abstract

A method is disclosed for manufacturing a disk drive. At least one disk is installed into a base, and a media cover is coupled to the base, wherein the media cover covers at least a portion of the disk. After installing the media cover, a head coupled to an actuator arm and a voice coil motor for rotating the actuator arm about a pivot are installed into the base. The media cover is then removed and an HDA cover is coupled to the base to form a head disk assembly (HDA). In one embodiment, the base comprises an aperture, and coupling the media cover to the base comprises inserting a pin into the aperture. In one embodiment, the aperture is also for coupling a printed circuit board to the base after removing the media cover.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to disk drives for computer systems. More particularly, the present invention relates to a media cover for manufacturing a disk drive.[0003]2. Description of the Prior Art[0004]FIG. 1 shows an exploded view of a prior art disk drive comprising a disk 2 rotated by a spindle motor 4, and a head 6 coupled to a distal end of an actuator arm 8 which is rotated about a pivot 10 by a voice coil motor (VCM) in order to actuate the head 6 over the disk 2. The disk 2, spindle motor 4, head 6, actuator arm 8, and VCM are enclosed in a head disk assembly (HDA) comprising a base 9 and a cover 11. The VCM comprises a voice coil 12 coupled to the base of the actuator arm 8 and one or more permanent magnets attached to a yoke 14. When the voice coil 12 is energized with current, the resulting magnetic flux interacts with the magnetic flux of the permanent magnets to generate a torque that rotates the actua...
