Abstract: A hard disk drive includes a magnetic writer and a magnetic recording medium, which includes data tracks with user data sections positioned between servo wedges. The servo wedges each can include multiple servo sectors. The hard disk drive also includes circuitry programmed to cause the magnetic writer to write user data to the multiple servo sectors in multiple servo wedges.

Abstract: A data storage system can provide low cost and optimized performance with a cartridge housing multiple separate data storage devices and each of the data storage devices being concurrently engaged by a device player. The device player may have a processor configured to analyze mechanical performance of each data storage device and data performance of data resident in each data storage device.

Abstract: An implementation of a system disclosed herein includes a control board including multiple cartridge slots and hardware for coupling each of the multiple cartridge slots to an associated storage cartridge. The system further includes multiple voice coil motor (VCM) actuator components mounted to the control board, each one of the multiple VCM actuator configured to contribute to an electromagnetic interaction that drives movement of an actuator arm within a storage cartridge coupled to one of the multiple cartridge slots.

Abstract: A Surface-Enhanced Raman Spectroscopy (SERS) device to perform accurate label-free long-read DNA sequencing. A Raman sensor has a hot spot defined by plasmonic nanostructures and excited by at least one laser. An immobilized DNA polymerase can be used to pull a DNA template strand to be sequenced through the hot spot.

Abstract: A data storage device includes a base, a shaft that extends perpendicular from the base, and a head stack assembly (HSA) having a first end to which a head is coupled and a second end that is movably mounted on the shaft. The data storage device also includes either a first actuator assembly or a second actuator assembly. The first actuator assembly includes a first coil-permanent magnet assembly that rotatably moves the HSA about the shaft, and a second coil-permanent magnet assembly that serves as a first elevator to linearly move the HSA along the shaft. The second actuator assembly includes a third coil-permanent magnet assembly that rotatably moves the HSA about the shaft, and a second elevator that linearly moves the HSA along the shaft and also moves a data storage device ramp in unison with the HSA.

Abstract: A beam steering control system includes a beam angle controller, a fast axis controller configured to receive a first command signal from the beam angle controller and configured to control a first axis component of a light pattern, and a slow axis controller arranged within a closed-loop system. The slow axis controller is configured to receive a second command signal from the beam angle controller and control a second axis component of the light pattern.
