摘要： A method of forming a recording head for use with a data storage medium in a data storage device. The method includes forming first and second writers of different target geometries. A first recording measurement is performed on one or more storage media using the first writer. A second recording measurement is performed on the one or more storage media using the second writer. Based on a comparison of the first and second recording measurements to a predetermined quantity, either the first writer or the second writer is selected to be operational in the data storage device.

摘要： A recording head includes a bearing surface, a first writer and a first shield structure for the first writer. The recording head also includes a second writer and a second shield structure for the second writer. The recording head further includes a magnetic bridge connecting the first shield structure to the second shield structure at the bearing surface.

摘要： A machine learning system and method. The machine learning system includes at least one computation circuit that performs a weighted summation of incoming signals and provides a resulting signal. The weighted summation is carried out at least in part by a magnetic element in which weights are adjusted based on changes in effective magnetic susceptibility of the magnetic element.
