Abstract: Systems and methods are disclosed for an actuator device or actuator control device to implement a low power savings mode. For example, a device can comprise an actuator arm including a first actuator and a second actuator, the second actuator configured to refine a movement of the actuator arm to a more precise position than use of merely the first actuator. A device can also comprise a control system configured to determine when the device is in an idle state and, when the device is in the idle state, disable the second actuator and perform a positional seek operation with the second actuator disabled. Power savings can occur from disabling the second actuator, which may also include disabling associated circuitry, such that it does not consume power or consumes a nominal (e.g., negligible or insignificant) amount of power during the associated seek operation.

Abstract: Systems and methods are disclosed for an improved utilization of parity within a data storage device, and manufacturing methods thereof. In some embodiments, a data storage device can implement an improved codeword redundancy process that can be utilized for data storage locations which were not previously scanned for defects. In some embodiments, a data storage device can implement an improved codeword redundancy process to store write data to a data storage location without having to perform a read operation prior to storing the write data to the storage location. The improved codeword redundancy process can include various methods of storing or updating an outer code codeword for the data to be stored.
Abstract: The present disclosure relates to a recording head that includes a write pole extending to a media-facing surface of the recording head; a near-field transducer extending to a media-facing surface of the recording head; a trailing return pole positioned between the write pole and the trailing edge; and a recessed portion that is recessed relative to the media-facing surface by a distance when no power is applied to the recording head. The trailing return pole is located in the recessed portion. The present disclosure also includes relates methods of making and detecting contact between a recording head and recording medium.

Abstract: Method and apparatus for enhancing performance of a storage device, such as a solid-state drive (SSD). In some embodiments, the storage device monitors a rate at which client I/O access commands are received from a client to transfer data with a non-volatile memory (NVM) of the storage device. A ratio of background access commands to the client I/O access commands is adjusted to maintain completion rates of the client I/O access commands at a predetermined level. The background access commands transfer data internally with the NVM to prepare the storage device to service the client I/O access commands, and can include internal reads and writes to carry out garbage collection and metadata map updates. The ratio may be adjusted by identifying a workload type subjected to the storage device by the client.

Abstract: A method includes partitioning a received data chunk into first and second data sectors to be stored in respective first and second store units. The method also includes generating first and second random keys. The method further includes encrypting the first data sector with the second random key, and encrypting the second data sector with the first random key. The first and second random keys are encoded with channel codes. Thereafter, the first encoded random key is appended to the first encrypted data sector to obtain first appended data, and the second encoded random key is appended to the second encrypted data sector to obtain second appended data.
