Abstract: A DNA sequencing device, and related methods, include a nanochannel sized to receive a DNA strand, a first electrode member exposed within the nanochannel, and a second electrode member exposed within the nanochannel and spaced apart from the first electrode to form an electrode gap. The second electrode member has a wedge shaped profile, and the first and second electrode members are operable to detect a change in electronic signal as the DNA strand passes through the electrode gap.

Abstract: Systems and methods are disclosed for enhanced garbage collection operations at a memory device. The enhanced garbage collection may include selecting data and blocks to garbage collect to improve device performance. Data may be copied and reorganized according to a data stream via which the data was received, or data and blocks may be evaluated for garbage collection based on other access efficiency metrics. Data may be selected for collection based on sequentiality of the data, host access patterns, or other factors. Processing of host commands may be throttled based on a determined amount of work to garbage collect a plurality of blocks, in order to limit variability in host command throughput over a time period.

Abstract: The disclosed technology provides a method that reduces time to recover in storage systems. In one implementation, the method comprises entering an idle status, determining if there is an incomplete band update operation, invalidating a media scratch pad (MSP) by clearing headers responsive to determining there is no incomplete band update operation, performing a power cycle, reading an MSP header, and determining if an MSP header is valid. If a rude power cycle occurs and the MSP header is determined to be valid, an MSP is examined, and restored if required. If a safe power cycle occurs, an MSP restore operation is not required, reducing time to recover.

Abstract: Apparatus and method for managing data in a multi-device data storage system. In some embodiments, a plurality of data storage devices are provided, each data storage device having a local driver circuit adapted to transfer data with a local memory module. A main driver circuit external to the plurality of data storage devices is configured to stream frequency modulated write data via parallel data transfer paths to the respective local driver circuits for concurrent transfer of the frequency modulated write data to the respective local memory modules.

Abstract: Optical connectors may include various portions, or structures, to provide a plurality of degrees of movement to optical ferrules. The optical ferrules may be linearly movable along one or more axes and rotationally moveable about one or more axes for alignment and coupling to corresponding optical ferrules. The optical connectors may be integrated with, or in conjunction with, other non-optical connectors such as electrical connectors, e.g., located on a drive carrier.

Abstract: A first time period is determined during which a first head driven by a first actuator will be performing a track-following operation. A second time period is also determined during which a second head driven by a second actuator will be performing a low-priority disk access operation that includes a seek. The first and second actuators are independently movable such that the first and second disk access operations are capable of being performed in parallel. If it is determined that the seek of the second head will impact servo control of the track-following operation of the first head, a start time of the seek of the second head is changed to correspond to a time that mitigates impacts to the track-following operation of the first head.
