The stiffener is coupled to the flexible circuit on a second side of the flexible circuit opposite the first side.

Abstract: An opener assembly for a data storage component testing system is disclosed. The opener assembly includes an actuator assembly with a first opener actuator and a body having a distal end, a proximal end, a first arm, and a second arm. The first and second arms extend between the proximal end and the distal end and define a spacing at the distal end. The first opener actuator is operatively coupled to the first and second arms and configured to actuate the actuator assembly between a closed position and an opened position.

Abstract: A data storage device includes at least one head supported by an actuator arm. The at least one head interacts with the at least one data storage disc when positioned over the at least one data storage disc. The data storage device further includes a split ramp for supporting the at least one head when the at least one head is moved away from the at least one data storage disc. The split ramp has a first ramp portion adjacent to a first outer diameter (OD) of the at least one data storage disc and a second ramp portion adjacent to the first ramp portion, such that the first ramp portion is between the second ramp portion and the first OD. At least one of the first ramp portion or the second ramp portion is independently moveable.

Abstract: Disclosed is an invention in the field of shielded sprayers. The present disclosure particularly relates to a spray shield which can utilize standard plastic bottles. In particular, a spray shield is described which attaches a standard plastic bottle to a trigger sprayer or wand sprayer assembly, wherein the plastic bottle is cut to provide an opening distally from the next portion of the bottle, allowing for the spray to be enclosed within the inner portion of the plastic bottle. The plastic bottle may be attached, incorporated, or anchored to the trigger sprayer or wand sprayer. The shield may be washable or disposable and is typically recyclable.

Abstract: A locking media pusher is coupled to a servo controlled stage and includes a protruding probe and a locking mechanism. The stage moves forward and backward along a base toward and away from a storage medium. If an eccentricity of a track on the storage medium exceeds a threshold, the storage medium is rotated to an orientation where the greatest eccentricity is directed toward the media pusher. The media pusher is moved toward the storage medium until a probe extending from the media pusher contacts the storage medium. The probe is locked within the media pusher. The stage and attached media pusher are retracted from the storage medium and the storage medium is unlocked. The magnitude of retraction of the stage is recorded. The stage is moved toward the storage medium a distance corresponding to the probe contact position plus the eccentricity magnitude to correct the eccentricity.

Abstract: This disclosure includes a system for aligning an unmounted head gimbal assembly (HGA) comprising a platform for a base plate of the HGA. The platform defines an X-Y plane. The system further comprises a compliant alignment pin extending beyond the platform in a Z-dimension perpendicular to the X-Y plane. The compliant alignment pin includes a tapered portion having a maximum diameter larger than a diameter of a boss hole in the base plate of the HGA. The compliant alignment pin is deflectable in the Z-dimension to allow the base plate of the HGA to register with the platform. The system further comprises a second alignment pin extending beyond the platform in the Z-dimension. The second alignment pin is configured to register with an HGA reference feature of the HGA when the boss hole of the HGA registers with the compliant alignment pin to precisely align the HGA relative to the compliant alignment pin and the second alignment pin.

Abstract: In one embodiment, an apparatus is provided for preparing a cassette spool. The apparatus includes: a supply reel for supplying and unrolling tape material on original backing paper; at least one cutting member for cutting unrolled tape material while on original backing paper; a cutting surface defined in a plane; a pivoting path member adapted to move from a first position aligned in the plane to a second position aligned at least partially out of the plane; at least one removing member for removing uncut unrolled tape material from original backing paper; and a cassette spool for rolling up unrolled cut tape material on original backing paper. In further embodiments, methods are provided for preparing a cassette spool with cut tape material on original backing paper.

Abstract: The invention is directed to methods and apparatus for repositioning a data storage disc on a spindle assembly, to reduce eccentricity of data on the disc. The eccentricity can be identified and be reduced automatically by determining the magnitude and direction of an eccentricity vector that representing a misalignment of a central point around which the data are arranged on a data storage disk with an axis of a spindle, and moving the disc so that the eccentricity vector is reduced. One technique for moving the disc is to push the edge of the disc so that the central point moves closer to the axis of the spindle.

Abstract: A manhole grade adjusting ring has an adjustable diameter with a V-shaped expansion lock bridging the ends of the ring. The expansion lock has radial flanges which are adjustably pinned in slots in the ends of the ring after the ring is expanded or contracted to fit a particular manhole frame using an expansion/contraction tool. The "V" is then hammered to expand the diameter of the ring so as to form a tight friction fit between the ring and the manhole frame.
