Introduction

James V Wiseman is a distinguished inventor based in Palo Alto, California, known for his significant contributions to disk drive technology. He holds six patents, showcasing his innovative spirit and technical expertise in the field of data storage systems.

Latest Patents

Among his latest inventions, Wiseman developed a patent titled "Disk drive correcting position error signal based on velocity of head." This disk drive technology includes a head actuated over a disk with multiple servo sectors defining servo tracks. The invention generates a position error signal (PES) in response to these servo sectors, estimating head velocity relative to the tracks. A correction value based on head velocity and PES allows for adjustments that improve the positioning of the head over the disk.

Another notable patent by Wiseman is titled "Methods to determine gross and fine positioning on a reference surface of a media." This innovation involves determining the position of a head along a stroke by locating marker-zones printed on a reference surface of a disk. Using a template pattern of pulses, the invention allows for the detection of marker-zone edges, leading to accurate gross and fine positioning of the head.
