Abstract
Description
- 1. Field of the Invention
- 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.
- 2. Description of the Prior Art
-
FIG. 1 shows an exploded view of a prior art disk drive comprising adisk 2 rotated by a spindle motor 4, and ahead 6 coupled to a distal end of anactuator arm 8 which is rotated about apivot 10 by a voice coil motor (VCM) in order to actuate thehead 6 over thedisk 2. Thedisk 2, spindle motor 4,head 6,actuator arm 8, and VCM are enclosed in a head disk assembly (HDA) comprising a base 9 and acover 11. The VCM comprises avoice coil 12 coupled to the base of theactuator arm 8 and one or more permanent magnets attached to ayoke 14. When thevoice 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 theactuator arm 8 about thepivot 10. Atang 16 attached to theactuator arm 8 interacts with acrash stop 18 to limit the stroke of theactuator arm 8, and also provides a latching mechanism (e.g., using a magnet) to maintain theactuator arm 8 in a latched position while the disk drive is powered down. Alternatively, theactuator arm 8 may be parked on a ramp located at the outer periphery of thedisk 2 when the disk drive is powered down. - During manufacturing, the HDA is passed through an assembly line of “stations” each responsible for installing particular components using appropriate installation tools. For example, one manufacturing station may install the spindle motor 4 into the base 9, another station may clamp the
disk 2 to the spindle motor 4, another station may install the head stack assembly (actuator arm 8,head 6, voice coil 12), another station may install thecrash stop 18, another station may install theyoke 14 of the VCM, and another station may install theHDA cover 11. Although manufacturing the HDA typically occurs in a clean room environment, there is still a risk that particles will contaminate the surface of thedisk 2 as the HDA passes through the various manufacturing stations. - There is, therefore, a need to protect against particles contaminating the disk surfaces while manufacturing the HDA of a disk drive.
- An embodiment of the present invention comprises a method of 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.
- Another embodiment of the present invention comprises a disk drive comprising a base including at least one disk and adapted to receive an actuator arm and a voice coil motor. The disk drive further comprises a media cover coupled to the base and covering at least a portion of the disk while leaving a portion of the base uncovered, wherein the uncovered portion is shaped so that the actuator arm and voice coil motor fit through the uncovered portion when installed into the base. In one embodiment, the media cover is formed from a portion of a HDA cover.

FIG. 2B illustrates how the uncovered portion of the media cover is shaped so that the actuator arm and voice coil motor fit through the uncovered portion when installed into the base. -
FIG. 2C shows the media cover coupled to the base after installing the actuator arm and voice coil motor. -
FIG. 3 illustrates an embodiment of the present invention wherein after removing the media cover and coupling the HDA cover to the base, a printed circuit board is coupled to the base using the same aperture for coupling the media cover to the base. -
FIGS. 2A-2C illustrate an embodiment of the present invention as a method of manufacturing a disk drive.FIG. 2A shows at least onedisk 2 is installed into a base 9, and amedia cover 20 is coupled to the base 9, wherein themedia cover 20 covers at least a portion of the disk 2 (FIG. 2B ).FIGS. 2B and 2C shows how after installing themedia cover 20, a head coupled 6 to anactuator arm 8 and a voice coil motor for rotating theactuator arm 8 about apivot 10 are installed into the base 9. Themedia cover 20 is then removed and anHDA cover 11 is coupled to the base to form a head disk assembly (HDA) as shown inFIG. 3 . - The voice coil motor may comprise any suitable components, but typically includes a
voice coil 12 coupled to the base of theactuator arm 8 and ayoke 14. In the embodiment ofFIG. 2A , theyoke 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, theyoke 14 may comprise top and bottom metal plates with attached magnets. In addition, acrash stop 18 may optionally be installed into the base 9 for limiting the movement of theactuator arm 8, wherein thecrash stop 18 may also comprise any suitable configuration. - In the embodiment shown in
FIG. 2A , the base comprises anaperture 22, and coupling themedia cover 20 to the base 9 comprises inserting apin 24 into theaperture 22. In one embodiment, thepin 24 is first inserted into themedia cover 20, and then themedia cover 20 is coupled to the base 9 by inserting thepin 24 into theaperture 22. In another embodiment, themedia cover 20 is placed onto the base 9 and then thepin 24 is inserted through themedia cover 20 and into the aperture in order to couple themedia cover 20 to the base 9. - In one embodiment, the
aperture 22 for coupling themedia cover 20 to the base 9 (FIG. 2A ) is also for coupling a printed circuit board to the base 9 after removing themedia cover 20.FIG. 3 shows an example of this embodiment wherein a printedcircuit board 26 is coupled to the bottom of the base 9 after installing theHDA cover 11. The aperture 22 (FIG. 2A ) for coupling themedia cover 20 extends through to the bottom of the base 9, and a screw (or other suitable fastener) is screwed into theaperture 22 to couple the printedcircuitry board 26 to the base 9. - The
media cover 20 may be formed from any suitable material (e.g., plastic, metal, etc.), and in one embodiment, themedia cover 20 is formed from a portion of anHDA cover 11. For example, anHDA cover 11 may be cut or stamped to form a suitably shapedmedia cover 20, including thehole 28 for inserting thepin 24 in the embodiment ofFIG. 2A . - The
media cover 20 may cover theentire disk 2 or a portion of thedisk 2, and in the embodiment shown inFIG. 2B , themedia cover 20 covers a substantial portion of thedisk 2. In other embodiments, themedia cover 20 may cover less of thedisk 2 and may also comprise other openings or features that facilitate installation tools and/or other disk drive components. For example, the media cover 20 may cover less of thedisk 2 to facilitate a merge tool for merging thehead 6 with thedisk 2. The media cover 20 may also comprise one or more “cut-outs” to facilitate installation of other components, such as a ramp near the outer periphery of thedisk 2 in disk drives that employ ramp load/unload.
