Abstract: A method includes partially forming a top chamfer on a disc substrate with a first brush, and partially forming a bottom chamfer on the disc substrate with a second brush. The method also includes completing the formation of the bottom chamfer with the first brush, and completing the formation of the top chamfer with the second brush.

Abstract: A method for serial and contemporaneous synthesis of disparate deoxy-ribonucleic acid (DNA) strands in an array of wells defined within a substrate. Each well in the array of wells contains a precursor nucleotide chain. A first subset of wells of the array of wells is designated not to receive a nucleotide of a specified nucleobase type and the first subset of wells is closed. A solution of a binding reaction enzyme and nucleotides of the specified nucleobase type bound with a corresponding chemical blocker is flowed over the array of wells. Nucleotides of the specified nucleobase type are received in each of a second subset of wells of the array of wells that are open and designated to receive the nucleotide of the specified nucleobase type. Received nucleotides of the specified nucleobase type are bound with assistance of the binding reaction enzyme to corresponding precursor nucleotide chains in the second subset of wells.

Abstract: A data storage system for use in a high radiation environment runs first and second operating time counters to monitor a field-programmable, gate array (FPGA) configured as a storage controller. Based on the first operating time counter passing a first threshold, the FPGA is fully reprogrammed. Based on the second operating time counter passing a second threshold less than the first threshold, the FPGA is partially reprogrammed.

Abstract: A method involves forming a recording head that comprises a waveguide, a write pole, and a near-field transducer proximate the write pole. The near-field transducer has an extended portion extending towards a surface of the recording head and operable to direct plasmons to a recording medium. The surface of the recording head is lapped to form a lapped surface. A resist or hardmask is patterned on the lapped surface in a region that encompasses the extended portion. The lapped surface is etched with the resist or hardmask pattern to form a media-facing surface such that the extended portion protrudes beyond the media-facing surface by a first distance, and the resist or hardmask is removed.

Abstract: A failure of a head is detected, the head reading from and writing to an affected surface of a disk of a disk drive. The failure prevents the head from writing to the affected surface but does not prevent the head from reading from the affected surface. In response to detecting the failure, a remediation is performed. The remediation involves determining spare capacity blocks on other surfaces of the disk drive different than the affected surface, and copying data from the affected surface to the spare capacity blocks via an internal copy function within the disk drive. The spare capacity blocks in place of the affected surface for data storage and retrieval subsequent to the failure.

Abstract: A laser-based molecular sequencing system includes a two-dimensional photonic crystal surface emitting laser (PCSEL) array including a plurality of PCSEL devices located in a first layer, each PCSEL device oriented in a direction perpendicular to the first layer. The system also includes a controller configured to modulate a bias on at least one PCSEL device of the plurality of PCSEL devices, the modulation configured to selectively operate each PCSEL device as an emitter or detector at a point in time based on the bias.

Abstract: A data storage system can utilize one or more data storage devices that employ a solid-state non-volatile read destructive memory consisting of ferroelectric memory cells. A leveling strategy can be generated by a wear module connected to the memory with the leveling strategy prescribing a plurality of memory cell operating parameters associated with different amounts of cell wear. The wear module may monitor activity of a memory cell and detect an amount of wear in the memory cell as a result of the monitored activity, which can prompt changing a default set of operating parameters for the memory cell to a first stage of operating parameters, as prescribed by the leveling strategy, in response to the detected amount of wear.

Abstract: A private set intersection protocol in which a third party may determine intersections of a first set of a first party and a second set of a second party. The third party may not obtain any information regarding the first set or the second set other than the intersection result. The protocol may be communicatively efficient and computationally efficient to allow for secure private set intersection to be performed.
