Abstract: A method includes adding new storage capacity to a data storage system, which has a pre-existing storage capacity. The method further includes rebalancing data from the pre-existing storage capacity to the new storage capacity in connection with a non-rebalancing operation performed on the pre-existing storage capacity.

Abstract: A light detection and ranging system can have a controller connected to an emitter and a detector. The controller may be configured to selectively move portions of the detector to increase a pixel resolution for a portion of a downrange field of view. The controller can utilize multi-spectral wavelength customization to further increase the pixel resolution of the detector.

Abstract: A heat-assisted magnetic recording head includes a near-field transducer (NFT). The NFT includes a plasmonic disk and a near-field oscillator pair. The near-field oscillator pair includes a receiving oscillator and an emitting oscillator. The receiving oscillator is operatively coupled to the plasmonic disk and configured to receive localized surface plasmons from the plasmonic disk and amplify a near field of the localized surface plasmons. The emitting oscillator is configured to receive the near field from the receiving oscillator and emit the near field toward a surface of a magnetic disk.
