摘要： The present invention provides a disc clamp for use with a disc stack assembly where the disc stack assembly is designed for rotation about an axis. The disc clamp includes a set of openings defined by a body, such that each opening has line symmetry about a line of reflection that intersects the axis. The disc clamp also includes a set of flanges, each which extends from the body into one of the openings. The disc clamp is made such that the set of openings has rotational symmetry about the axis and the set of flanges is rotationally asymmetrical about the axis.

摘要： A disc clamp for a disc drive used to secure a disc stack in position when the disc is mounted to a hub. The disc clamp is annular with a central opening and has three tabs. The three equidistantly spaced tabs extend radially inward from the circumferential edge of the central opening. The disc clamp is resiliently flexible and has a continuous annular disc contact region adjacent to an outer circumferential edge. The disc clamp also has at least three screw openings each for receiving a screw fastener to fasten the disc clamp to the hub in the clamping position. The disc clamp resiliently flexes in the clamping position to cause the annular disc contact region to bear against the surface of the outermost stacked disc to clamp the disc stack against radial and axial movement.

摘要： A clamp including an inverted spring portion and a plurality of tabs about a circumference of an inner portion of the clamp. The inverted spring portion of the clamp is insertable into a groove of a clamping interface between a flange and an outer portion thereof to align the plurality of tabs proximate to the flange. As described, the clamp provides a low profile interface for clamping discs to a spindle assembly which snap fits into the groove to provide a screwless clamp interface. Other features and benefits that characterize embodiments of the present invention will be apparent upon reading the following detailed description and review of the associated drawings.

摘要： A method for forming a disc stack assembly suitable for use in a disc drive. A number of discs are loaded onto a spindle motor hub and a disc clamp assembly is installed to secure the discs to the hub. The disc clamp assembly includes an annular retaining ring and a substantially planar, disc shaped clamp plate. The annular retaining ring is secured within an annular ring recess of the spindle motor hub and deforms the clamp plate so that the clamp plate applies an axially directed clamping force to the discs. The disc clamp includes an annular hat flange. The disc stack assembly is preferably balanced by selectively removing material from the hat flange or by attaching a balance weight to the hat flange.

摘要： A method for writing servo patterns on at least one disc in a disc drive that has a first set of tracks and a second set of tracks on a major surface of the disc includes stepping between the tracks of the first set of tracks at a first constant angle, and stepping between the tracks of the second set of tracks at a second constant angle. Stepping between tracks in the first group or the second group includes selecting two adjacent tracks from either the first group of tracks or the second group of tracks, and determining the angle through which an actuator assembly must be rotated between the two adjacent tracks selected to produce a selected track pitch. The method produces a disc for a disc drive with a first set of tracks, and a second set of tracks in which the track pitch varies across the set of tracks.
