    Abstract: A device includes a servo controller that includes or that is coupled to memory. The memory stores multiple distinct disturbance control schemes. The servo controller is configured to select and implement one of the disturbance control schemes in response to receiving a command from a host. The servo controller can be implemented on a system on a chip.

    Abstract: An alternate reality, such as virtual reality or augmented reality, environment can experience optimized performance with a data system arranged with an interaction device connected to a virtual reality assembly. Base content and user content can respectively be downloaded and stored to a local data storage of the virtual reality assembly. The content may be utilized to proactively generate comprehensive content that consists of merged aspects of the base content and the user content. The comprehensive content can then be executed to create an immersive digital reality conveyed to a user via the interaction device.

    Abstract: A disk drive comprises non-volatile rotatable media and a controller operatively coupled to the non-volatile rotatable media. The controller is configured to receive a series of host commands to be executed by the controller and generate a command execution sequence comprising the series of host commands. A task manager, integral or coupled to the controller, is configured to receive a plurality of background tasks comprising a least two priority background tasks to be executed by the controller along with execution of the series of host commands, and insert one or more of the at least two priority background tasks into the command execution sequence while maintaining a specified ratio of priority background task execution and host command execution substantially constant. The controller is configured to execute the command execution sequence with the one or more inserted priority background tasks.

    Abstract: A hard disk assembly (HDAs) that include a tuning data memory at least including tuning data regarding the HDA. The HDAs may lack an internal disk controller, but rather may communicate the tuning data and/or other HDA-specific data (e.g., firmware, certification data, etc.) to a reader device comprising a disk controller. In this regard, the reader device may coordinate with the HDA once the tuning data is received to operate the HDA to perform TO commands in response to commands received at the reader device from a host. In turn, upon failure of an HDA, a new HDA may be swapped into place to communicate with the reader device. Because the HDAs may lack onboard disk controllers, the cost and complexity of each HDA may be reduced.

    Abstract: A data storage device that includes a data storage medium and a controller communicatively coupled to the data storage medium. The controller is configured to receive commands from a host and to detect a hung state in the data storage device. The controller is also configured to determine an execution status of a command, of the commands from the host, associated with the hung state. The controller is further configured to dynamically carry out a self-recovery operation in the data storage device to clear the hung state. The self-recovery operation includes steps that depend upon the execution status of the command associated with the hung state.
