  • Adaptive HAMR laser power data storage device
    Patent number: 9478248
    Abstract: A data storage device and associated methods may provide at least a data storage medium that is separated from a heat assisted magnetic recording data writer and is connected to a controller. The controller can be configured to change a laser power of the heat assisted magnetic recording data writer in response to a tested bit error rate of a median data track of a plurality of adjacent data tracks reaching an identified threshold.
    Type: Grant
    Filed: October 13, 2014
    Date of Patent: October 25, 2016
    Assignee: Seagate Technology LLC
    Inventors: Michael A. Cordle, Franklin P. Martens, Alfredo Sam Chu, Shawn Stephen Silewski, Tim Rausch

  • Measurement of test object with stacked features
    Patent number: 7817259
    Abstract: An apparatus and associated method for measuring spatial characteristics of a test object with stacked features. First and second measurement assemblies for measuring opposing first and second planar features, respectively, of a test object, by directing light beams into a gap between the features to measure a position and a static attitude of each feature.
