  • Patent number: 9099133
    Abstract: A disk drive is disclosed comprising a disk comprising a plurality of servo tracks, wherein each servo track comprises a plurality of servo sectors, and an actuator for actuating a head over the disk in response to an actuator control signal. The servo sectors are read to generate a first sequence of control samples x[k] at a sample frequency corresponding to a frequency of the servo sectors. A hybrid upsample filter is used to upsample by a factor of N the first sequence of control samples x[k] to generate a second sequence of control samples y[ki], wherein the hybrid upsample filter provides a higher phase gain than a zero-order type upsample filter at frequencies less than one kilohertz, and approximately the same attenuation as a first-order type upsample filter around the sample frequency. The actuator control signal is generated in response to the second sequence of control samples y[ki].

  • Patent number: 8743503
    Abstract: A disk drive is disclosed comprising a head actuated over a disk comprising a plurality of servo tracks defined by servo sectors. The head is positioned over a first servo track, and a first position error signal (PES) by reading a first servo sector during a first revolution of the disk and in response to a first compensation value. A second compensation value is updated for a second servo sector based on the first PES during the first revolution of the disk. A second PES is generated by reading the second servo sector during the first revolution of the disk and in response to the updated second compensation value. The first compensation value is updated for the first servo sector based on the second PES during the first revolution of the disk. The head is actuated over the disk in response to the first PES and the second PES.

  • Patent number: 8709892
    Abstract: A method for fabricating a flash memory device where the flash memory device includes a substantially uniform size and spatial distribution of nanoparticles on a tunnel oxide layer to form a floating gate. The flash memory device may be fabricated by defining active areas in a substrate and forming an oxide layer on the substrate. A self-assembled protein lattice may be formed on top of the oxide layer where the self-assembled protein lattice includes a plurality of molecular chaperones. The cavities of the chaperones may provide confined spaces where nanocrystals can be trapped thereby forming an ordered nanocrystal lattice. A substantially uniform distribution of nanocrystals may be formed on the oxide layer upon removal of the self-assembled protein lattice such as through high temperature annealing.
