    Abstract: A slider includes an array of two or more transducer sets offset from one another in a cross-track direction. Each transducer set includes at least one writer and at least one reader. All of the transducer sets are configured to operate simultaneously to perform any combination of reading and writing on two or more tracks of a recording medium. At least one actuator is included between two the transducer sets. The actuator is configured to adjust a cross-track spacing between the two transducer sets in response to a control current.

    Abstract: A storage device disclosed herein includes a transducer head with a proximity sensor that generates head-disc proximity signals, a digitizer configured to convert the analog proximity signals from the proximity sensor to digitized sample data, a discrete wavelet transformation (DWT) module configured to analyze the digitized sample data by performing an enhanced DWT on the digitized sample data to generate DWT coefficients, and a modal filter configured to determine dominant head-disc interference (HDI) modes for a transducer head by analyzing the DWT coefficients.

    Abstract: An apparatus includes a controller capable of being coupled to a host interface and a memory device. The memory device includes two or more non-hierarchical, non-volatile memory units having different minimum addressable data unit sizes. The controller is configured to at least perform determining a workload indicator of a data object being stored in the memory device via the host interface. The controller selects one of the memory units in response to the workload indicator of the data object corresponding to the minimum addressable data unit size of the selected memory unit corresponding to the workload indicator. The data object is stored in the selected memory unit in response thereto.

    Abstract: Method and apparatus for managing data in a memory. In accordance with some embodiments, a first data object and an associated first ECC data set are generated and stored in a non-volatile (NV) main memory responsive to a first set of data blocks having a selected logical address. A second data object and an associated second ECC data set are generated responsive to receipt of a second set of data blocks having the selected logical address. The second data object and the second ECC data set are subsequently stored in the in the NV main memory responsive to a mismatch between the first ECC data set and the second ECC data set.

    Abstract: A data storage apparatus is presented that includes a well structure comprising a suspension medium, and a magnetic particle disposed in at least a portion of the well structure. A control system is configured to represent a data state corresponding to a positioning of the magnetic particle within the well structure, the magnetic particle moved responsive to an applied field and a present material state of the well structure. Various addressable arrays of well structures and associated control elements can be established to form data storage devices.
