  • Patent number: 9190079
    Abstract: A magnetic transducer has air-bearing surface (ABS) and includes a main pole and at least one coil. The coil(s) energize the main pole. The main pole includes a yoke and a pole tip having an ABS-facing surface. The pole tip includes a sidewall having a radius of curvature and a chisel angle. The chisel angle is measured between a yoke direction perpendicular to the ABS and a tangent the sidewall. The chisel angle for the pole tip continuously increases in the yoke direction to a maximum a first distance from the ABS-facing surface in the yoke direction. The radius of curvature for the pole tip has a minimum radius of curvature a second distance from the ABS-facing surface in the yoke direction. The first distance is greater than the second distance.

    Abstract: Described herein are systems and methods for correcting a data set and classifying the data set in an integrated manner. A training data set, a training class set, and a test data set are received. A first classifier is generated for the training data set by applying a machine learning technique to the training data set and the training class set, and a first test class set is generated by classifying the elements in the test data set according to the first classifier. For each of multiple iterations, the training data set is transformed, the test data set is transformed, and a second classifier is generated by applying a machine learning technique to the transformed training data set. A second test class set is generated according to the second classifier, and the first test class set is compared to the second test class set.
