Abstract: The presently disclosed technology is directed to maximizing cleanliness, reliability, and space efficiency within a jukebox-style HDD, while minimizing overall cost of the HDD. In an effort to reduce the movement of a robotic arm assembly, cassettes within a jukebox-style HDD may be configured to be magnetically repositionable to replace some of the movement of the robotic arm assembly, without adding another significant source of potential mechanical failure within the HDD enclosure. Further, the overall number of moving parts is reduced, which may improve reliability of the HDD, as well as cleanliness within the HDD enclosure.

Abstract: A microfluidic system includes a fluidic platform having a surface, a first liquid disposed onto the fluidic platform, and a droplet disposed onto the first liquid. The first liquid has a first temperature. The droplet has a second temperature higher than the first temperature so that the droplet is levitated above the first liquid by a cushion of vapor of the first liquid. In an embodiment, a device is configured to provide a magnetic field that has variable strength across the surface. A location of a magnetic droplet relative to the surface area is affected by the magnetic field. A method includes providing a fluidic platform, providing a magnetic field, introducing a first liquid onto the fluidic platform, introducing a first magnetic droplet onto the first liquid, and locally varying the magnetic field.

Abstract: A data storage device includes a ramp that supports at least one head, and a retraction mechanism that moves the ramp from a non-retracted position to a retracted position. The movement of the ramp is enabled by at least one of expansion or contraction of at least a portion of the retraction mechanism. The data storage device further includes a ramp retraction control module operably coupled to the retraction mechanism. The ramp retraction control module provides the retraction mechanism with a first control signal that causes the retraction mechanism to move the ramp from the non-retracted position to the retracted position.

Abstract: A data storage device includes a base, a shaft that extends perpendicular from the base, and a head stack assembly (HSA) having a first end to which a head is coupled and a second end that is movably mounted on the shaft. The data storage device also includes either a first actuator assembly or a second actuator assembly. The first actuator assembly includes a first coil-permanent magnet assembly that rotatably moves the HSA about the shaft, and a second coil-permanent magnet assembly that serves as a first elevator to linearly move the HSA along the shaft. The second actuator assembly includes a third coil-permanent magnet assembly that rotatably moves the HSA about the shaft, and a second elevator that linearly moves the HSA along the shaft and also moves a data storage device ramp in unison with the HSA.

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 system can provide low cost and optimized performance with a cartridge housing multiple separate data storage devices and each of the data storage devices being concurrently engaged by a device player. The device player may have a processor configured to analyze mechanical performance of each data storage device and data performance of data resident in each data storage device.

Abstract: A data storage library includes a number of storage cartridges arranged in a rack accessed by a actuated media player. The actuated media player is adapted to move the along a plane relative to a fixed subset of the storage cartridges in the rack to and to selectively couple to each storage cartridge of the fixed subset to facilitate selective read/write access.

Abstract: An implementation of a system disclosed herein includes a control board including multiple cartridge slots and hardware for coupling each of the multiple cartridge slots to an associated storage cartridge. The system further includes multiple voice coil motor (VCM) actuator components mounted to the control board, each one of the multiple VCM actuator configured to contribute to an electromagnetic interaction that drives movement of an actuator arm within a storage cartridge coupled to one of the multiple cartridge slots.
