Abstract: A method for depositing a material from a solution to a surface is provided. The method includes depositing, through a deposition channel of a material depositor, the solution in a rich state to the surface, wherein the solution in the rich state includes an initial concentration of the material, onto a surface, applying a predefined electrical output, by the material depositor, through the deposited solution to adhere the material to the surface, and to yield the solution in a depleted state wherein the solution in the depleted state contains a different concentration of the material from the rich solution, and removing, through a removal channel in the material depositor, the deposited solution in the depleted state. The material depositor includes a hydrophilic region defined by a hydrophilic surface through which the material depositor conducts the depositing and the removing and a hydrophobic barrier circumscribing the hydrophilic region.

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: The slow speed of conventional selective electroplating and L-PED (and further requirement of a series of masks in the case of selective electroplating) necessary to generate a metallic three-dimensional object makes conventional selective electroplating and L-PED not viable for mass manufacturing metallic three-dimensional objects. The presently disclosed technology generally utilizes electroplating and L-PED technologies with a screen electroplating process. The screen electroplating process disclosed herein is capable of achieving a faster throughput and a lower workpiece temperature than traditional 3D printing processes can provide, particularly traditional metal 3D printing processes. As a result, the presently disclosed screen electroplating process is able to achieve much faster results in printing a complex three-dimensional metallic structure using electroplating.

Abstract: A data storage system include a disk drive having a rotating ramp assembly that may be moved between an engaged and disengaged position. The rotating ramp assembly may include a ramp extension that is not disposed in overlapping relation to a data storage disk location in the drive when in the disengaged position. However, in the engaged position, the ramp extension may overhang a portion of the data storage disk location. In turn, the head extension may include a ramp surface that allows a head assembly to move to a head parking surface when the rotating ramp assembly is in the engaged position. IN turn, the rotating ramp assembly may be rotated while maintaining the head assembly on the head parking surface, which may be arcuate and extend about at least a portion of the rotating ramp assembly.

Abstract: A storage system includes a media player including a preamplifier that is adapted to provide data access to a storage cartridge lacking an independent read/write preamplifier. The media player couples to the storage cartridges across an interconnect, and the storage cartridge is adapted to perform data access operations responsive to signals received from the media player through the interconnect.

Abstract: A data storage library includes multiple storage cartridges arranged on a rack; read/write control electronics integrated within a media player assembly; and actuation means for achieving relative movement between media player assembly and the multiple storage cartridges in the rack to allow the read/write control electronics within the media player assembly to selectively couple with and provide data access to at least a subset of the multiple storage cartridges.
