Abstract: Method of utilizing a nanochannel in combination with at least one magnetic sensor for detecting (e.g., identifying) molecules, cells, and other analytes. Particularly, the method includes bringing molecules, labeled with magnetic nanoparticles (MNPs), in close proximity to the magnetic sensor to identify the molecules via an output signal from the magnetic sensor. The method is particularly suited for identifying nucleotides of DNA and RNA strands.

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: An active metasurface that provides low-loss and high-bandwidth modulation control of light includes a number of cells arranged on a substrate. A controller dynamically alters a voltage differential supplied to the electrodes of each of the cells is adapted to alter refractive index of each of the high-index dielectric blocks in order to controllably steer light exiting the cell.

Abstract: An active metasurface includes a number of periodically-repeated unit cells arranged on a substrate that each include a plasmonic waveguide shaped and sized to provide a cutoff mode that captures light of a target wavelength. The active metasurface includes an index modulation controller that controllably varies a voltage differential across each one of the periodically-repeated cells to change a phase of light incident on the metasurface.

Abstract: Methods of DNA sequencing from a template strand via DNA polymerase immobilized on a magnetic sensor. The methods include forming a complementary strand by the DNA polymerase from individual magnetic nanoparticle (MNP)-labeled nucleotides, and obtaining a signal from the magnetic sensor to identify the MNP and thus the nucleotide. The process can be repeated until the entire complementary strand is formed and identified.

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.
