Abstract: In one implementation, the disclosure provides a method comprising detecting one or more areas of a storage medium having a data pattern with a plurality of consecutive bits, where the consecutive bits have the same polarity. The method further comprises encoding additional information on a section of the one or more detected areas, where the section of the one or more detected areas has a signal to noise ratio (SNR) higher than SNR of the other areas of the storage media.

Abstract: A method for scanning for flaws on a magnetic recording medium is disclosed. The magnetic recording medium has a first set of nonconsecutive data tracks and a second set of nonconsecutive data tracks. The method includes writing a test pattern to only the first set of nonconsecutive data tracks of the magnetic recording medium, reading of the test pattern written to the first set of nonconsecutive data tracks, and identifying flaws within the first set of nonconsecutive data tracks and the second set of nonconsecutive data tracks based on the reading the test pattern.

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: Technologies are described herein for utilizing multiple, wide readers to read narrow data tracks on a magnetic recording media in a storage device. A system for reading a data track on a magnetic recording media comprises a plurality of reader elements, the width of each reader element being an integer greater than 1 multiple of a width of the data tracks on the recording media. The system further comprises a multi-reader decoder module operably connected to the plurality of reader elements. Each of the reader elements is configured to read a magnetic signal from the magnetic recording media. The multi-reader decoder module is configured to receive a read signal from each of the reader elements, and decode the data on the data track based on the read signals from the reader elements.

Abstract: Optimization of an aerial density capability (ADC) leveraging different qualities of media surfaces to which sub-portions of an encoded data portion are written. That is, data may be encoded to generate an encoded data portion according to a coding scheme. In turn, the encoded data portion may be divided into a plurality of sub-portions, each of which may be written to different media surfaces in a storage drive. The sub-portions may be read from the different media surfaces and combined to generate a recreated encoded data portion that is decoded using the coding scheme. As the encoded data portion is divided into sub-portions, the combined sub-portions may provide different error rates or signal-to-noise ratios that may allow for lower quality sub-portions to be assisted during the decoding process by higher quality sub-portions.

Abstract: An edge node has a central processing operable to gather sensor node data via a sensor and store at least part of the sensor node data locally in a public region of a persistent storage. The edge node backs up duplicate portions of the sensor node data to public storage regions of peer-edge nodes. The edge node receives private data from a host that is coupled to the edge computing node and the peer edge nodes, and stores the private data in a private region of the persistent storage. The private region is protected from the peer edge nodes using distributed key management.
