Abstract: A method includes creating a table with a plurality of cells indicative of intersections of tracks and wedges on a data storage disc surface. The method also includes storing disc pending command information for different disc pending commands in corresponding different cells of the plurality of cells according to locations for the different disc pending commands on the data storage disc surface. The method further includes searching the table for one or more next disc pending commands of the different disc pending commands to schedule for execution.

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: The present disclosure relates to devices, circuits, and methods of determining power consumption in an electronic device (e.g., HDD) so that the determined power consumption can be used to determine a concentration of the gaseous oxidizing agent component in an interior gas space of the sealed enclosure and/or actively supply gaseous oxidizing agent component to the interior gas space of the electronic device if the determined power consumption is below a threshold value.

Abstract: A method includes calculating, by a data storage device processor, at least one access trajectory from a first disc surface location to at least one second disc surface location at which at least one primary data access operation is to be carried out. The method also includes determining, by the data storage device controller, whether an opportunity to commence at least one secondary data access operation exists along or proximate to the at least one access trajectory from the first disc surface location to the at least one second disc surface location.

Abstract: A wear mitigation system can be implemented in a data storage device. A data storage medium may be separated from a transducing head by an air bearing. A controller connected to the data storage medium and transducing head can be configured to reassign a physical address of the data storage medium from an unusable condition to a usable condition as a result of a self-healing of the data storage medium predicted by the controller.

Abstract: A data storage system can consist of a number of data storage devices each having a non-volatile memory, a memory buffer, and an error detection module. The memory buffer may store a first data block comprising a front-end first-level error detection code assigned by the error detection module. The non-volatile memory can consist of a second data block having a back-end first-level error detection code and a second-level error detection code each assigned by the error detection module.

Abstract: Embodiments described herein are operable in a computing system. The computing system receives first and second commands (e.g., I/O commands). The computing system determines that the first command has a higher priority than the second I/O command, and queues the second command for servicing at a later time. The computing system services the first command, and services the second command after a timeout period based on performance degradation limit that decreases command processing performance of the computing system, overrides the timeout period, and increases a probability of executing the second command.

Abstract: A data storage system includes data storage and random access memory. A sorting module is communicatively coupled to the random access memory and sorts data blocks of write data received in the random access memory of the data storage. A storage controller is communicatively coupled to the random access memory and the data storage and being configured to write the sorted data blocks into one or more individually-sorted granules in a granule storage area of the data storage, wherein each granule is dynamically constrained to a subset of logical block addresses. A method and processor-implemented process provide for sorting data blocks of write data received in random access memory of data storage. The method and processor-implemented process write the sorted data blocks into one or more individually-sorted granules in a granule storage area of the data storage, wherein each granule is dynamically constrained to a subset of logical block addresses.
