A data storage device includes a stack of discs mounted on a spindle and a pivot block rotatably mounted around a shaft. The data storage device also includes an arm having first and second ends, with the first end supporting a head and the second end movably attached to the pivot block. The data storage device further includes an ultrasonic piezoelectric actuator that moves the arm along the pivot block to enable the head to interact with data storage surfaces of the discs.

Data storage drive with a vertically translatable actuator arm

A hard disk drive includes a base deck and a cover. The cover is coupled to the base deck to create an enclosure. The hard disk drive also includes tape that covers at least a portion of the cover and the base deck. The tape includes an adhesive layer, which includes an adhesive material and a moisture-absorbent material.

Flexible desiccant tape

An exemplary data storage device includes an actuator arm assembly, a top guide rail, a bottom guide rail, and a first ball bearing. The actuator arm assembly includes a first post defining a pivot axis that is inclined between about 5 degrees and about 25 degrees from a horizontal plane defined by a data storage disk surface. The top guide rail includes a first rolling surface that is parallel to the pivot axis. The bottom guide rail is spaced from the top guide rail and includes a second rolling surface that is parallel to the first rolling surface. The first ball bearing includes a first inner race and a first outer race, the first inner race surrounding the first post, and the first outer race in contact with the first rolling surface or the second rolling surface. An exemplary method of assembling a data storage device is also described.

Ball bearing cartridge for linear actuator

A data storage device includes a base, a data storage disk, an actuator arm, a suspension, and a piezoelectric actuator. The data storage disk is attached to the base and has a read/write surface defining an x-y plane. The actuator arm is attached to the base at a first pivot point to rotate parallel to the x-y plane. The suspension is attached to the actuator arm at a second pivot point, the suspension having a first end comprising a curved edge surface, and a second end supporting a head that is configured to interact with the read/write surface. The piezoelectric actuator is disposed on the actuator arm and comprises a biasing finger configured to contact the curved edge surface to rotate the suspension parallel to the x-y plane about the second pivot point. An actuator arm assembly and a method of use are also described.

Zero skew with ultrasonic piezoelectric swing suspension

The invention relates to a bioreactor comprising a chamber for containing cells or tissue cultures within a culture medium. The bioreactor also comprises a detector capable of detecting a change in one or more metabolites associated with growth of the cell or tissue cultures within the chamber and a chamber drive capable of rotating the chamber at a first speed about a first axis and a second speed about a second axis, the second axis being disposed at an angle relative to the first axis. In use, the magnitude of the first speed and the second speed are independently variable of each other.
