Abstract: A data storage system for use in a high radiation environment includes an array of storage drives. Each storage drive includes a non-radiation-hardened drive controller, a non-radiation-hardened, non-volatile, storage medium, and a non-radiation-hardened volatile memory. The system includes a radiation-hardened storage controller coupled to the array. The radiation-hardened storage controller provides failure-resistant data redundancy among the storage drives of the array and provides host access to the array.

Abstract: A method includes detecting, by a first data storage device, an error when reading data from the first data storage device. The method further includes correcting a portion of the error, by a controller of a host system, using host-level outer codes; and communicating, by the controller, error correction information to the first data storage device in response to correcting the portion of the error using the host-level outer codes.

Abstract: A data storage device includes a data storage disc, an arm, a head, a rotary actuator, and an elevator. The disc has a read/write surface defining an x-y plane. The arm includes a load beam. The head is supported by the load beam, and the head is configured to interact with the read/write surface. The rotary actuator is configured to move a first portion of the arm about a first pivot axis in the x-y plane. The elevator is configured to move the arm in a z direction relative to a vertical surface and is configured to frictionally engage the vertical surface to hold the arm at a z direction position while allowing the rotary actuator to move the first portion of the arm about the first pivot axis. In another aspect, an apparatus includes a stack block, first and second clamp arm assemblies, and first and second piezoelectric actuators.

Abstract: The present disclosure describes a system and methods for positioning a configured number of biomaterials on a surface. The method disclosed includes the formation of a membrane mask structure including a configured number of nanopores. The nanopores are generally sized to be the same size as, or slightly larger than a single target biomaterial. The masking membrane is then adhered to a substrate. The substrate may include a raw substrate, or may be functionalized for the purpose of binding biomaterials with greater attraction. A solution including the target biomaterials is then exposed to the masking membrane. One biomaterial is able to adhere to the substrate through each nanopore. The solution is rinsed from the membrane surface leaving only the biomaterial that has adhered to the substrate with a relatively strong binding force. The masking membrane may then either remain or may be removed.

Abstract: A method for reducing noise in a read signal due attributable to read element asymmetry provides for transmitting a write signal through a write precompensation circuit that shifts rising edges and falling edges of each of pulse in the write signal by a select magnitude and in opposite directions. After the write signal is encoded on a media, a corresponding read signal is read, with a read element, from the media. The method further provides for transmitting the read signal through a magnetoresistive asymmetry compensation (MRAC) block that is tuned to correct second-order non-linearities characterized by a particular set of distortion signatures. The select magnitude of the waveform shift applied by the write precompensation circuit introduces a non-linear signal characteristic that combines with non-linear signal characteristics introduced by the read element to generate one of the particular distortion signatures that is correctable by the MRAC block.

Abstract: A data storage device includes at least one data storage medium. The data storage device also includes a workload rating associated with data access operations carried out on the at least one data storage medium. The data storage device further includes a controller configured to enable performance of the data access operations, and change a rate of consumption of the workload rating by internal device management operations carried out in the data storage device in response to a change in a workload consumed by host commands serviced by the data storage device.
