Abstract: A system includes a library compartment, a player and a gas generator. The library compartment houses a plurality of data storage disks. The player is external to the library compartment and comprises a head that is configured to interact with at least one of the plurality of data storage disks. The gas generator is fluidly connected to the player. An embodiment includes a partition between the library compartment and player, the partition including a selectively openable interlock. In an embodiment, the player has a negative fluid pressure relative to the library compartment. A method of controlling an environment in a disk player is also described. The method includes detecting a composition of a fluid environment in the disk player and detecting a pressure of the fluid environment in the disk player.

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 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: A system includes a read/write controller removably coupled to a storage drive. Responsive to detection of a coupling between the read/write controller and the storage drive, the read/write controller retrieves key information from the storage drive, uses the key information to locate adaptives associated with the primary storage medium, and loads the adaptives into volatile memory to configure read/write settings for access to the primary storage medium.

Abstract: A secure cartridge-based storage system includes a set of read/write control electronics on a shared controller adapted to removably couple with each of a plurality of storage cartridges. Data blocks within primary non-volatile memory of the cartridge-based storage system collectively comprise a main store with information-theoretic security. The shared controller incorporates various controls for providing selective data access to individual data magazines and/or cartridges as well as for partitioning user data and writing the partitioned data according to an information-theoretic security scheme and reading the partitioned data and reconstructing the user data from the partitioned data.
