Abstract: A hard disk drive includes a cover coupled to a base deck to create an enclosure. The hard disk drive further includes data-recording components and non-data-recording components positioned within the enclosure. At least one of the non-data-recording components includes a surface with a surface treatment that promotes condensation of water vapor.

Abstract: Systems and methods are disclosed for hardware-based read sample averaging in a data storage device. In one example, a read channel circuit including a buffer memory is configured to receive a read instruction to read a selected sector, obtain detected sample values for the selected sector, and determine whether the read instruction corresponds to a re-read operation for the selected sector based on determining whether there are stored samples for the selected sector already stored to a locked buffer entry of the buffer memory. When there are stored sample values stored to the locked buffer entry, the example read channel circuit determines the re-read operation is occurring, and performs read sample averaging based on the detected sample values and the stored sample values to produce averaged sample values. Other examples and configurations are also described.

Abstract: A method includes monitoring an amount of power of a power supply being used by a voice-coil motor (VMC) during a seek operation, detecting that the amount of power has crossed a threshold during the seek operation, and modifying a subsequent seek operation in response to detecting that the amount of power has crossed the threshold.

Abstract: Systems and methods for wireless enabled security in relation to a storage drive are described. In one embodiment, the systems and methods may include receiving, at a storage drive, a request from a host of the storage drive. In some cases, the request may be received via a wired connection between the storage drive and the host. In some embodiments, the systems and methods may include determining whether the request is flagged by the host as a secure connection request, processing the request upon determining the request is not flagged as a secure connection request, and establishing a wireless connection with the host upon determining the request is flagged by the host as a secure connection request.

Abstract: Systems and methods are disclosed for command status polling at a flash queue of a non-volatile memory device. The flash queue may be configured to perform polling on the status of flash operations without direct oversight from the data storage controller or firmware. In certain embodiments, a flash queue circuit may be configured to receive, from a data storage controller of a nonvolatile solid state memory (NVSSM) data storage device, one or more commands to access a flash memory of the NVSSM data storage device, each command of the one or more commands including one or more instructions. The flash queue circuit may execute the one or more commands to access the flash memory, evaluate a status response from the flash memory at the flash queue circuit, and re-execute a sequence of instructions of the one or more commands based on the status response.

Abstract: Methods, systems, and apparatuses are described for provisioning storage devices. An example method includes specifying a logical zone granularity for logical space associated with a disk drive. The method further includes provisioning a zone of a physical space of the disk drive based at least in part on the specified logical zone granularity. The method also includes storing compressed data in the zone in accordance with the provisioning.

Abstract: Embodiments of the present disclosure demonstrate a lapping carrier system for a bar to be lapped. The lapping carrier system may be configured with a single piece insert whose bridge is separated from a plurality of joints of the carrier insert by a varying distance. The varying distance can be greater at a medial portion of the bridge than at an end portion of the bridge to collectively form a parabolic shape. In some embodiments, a lapping insert can include a bridge with its length longer than the bar. In some embodiments in a lapping insert, the centerline between the end joint edge and the end finger edge extends beyond the edge of bar.

Abstract: A data storage library includes a number of storage cartridges arranged in a rack accessed by a actuated media player. The actuated media player is adapted to move the along a plane relative to a fixed subset of the storage cartridges in the rack to and to selectively couple to each storage cartridge of the fixed subset to facilitate selective read/write access.

Abstract: A recording surface of a magnetic disk is divided into first and second zones. A first head of a first actuator arm assembly reads from and/or writes to the first zone exclusively. A second head of a second actuator arm assembly reads from and/or writes to the second zone exclusively. The first and second head are capable of simultaneously reading from and writing to the recording surface.

Abstract: A method includes providing a device with transmitter parameters set to default factory values. The method also includes receiving, in the device, one or more write commands with test data patterns, and executing, in the device, the one or more write commands to store the test data patterns on a non-transitory data storage medium of the device. The method further includes receiving, in the device, one or more read commands for the test data patterns, and reading the test data patterns from the non-transitory data storage medium. The read test data patterns are communicated by a signal that is sent via the device transmitter. A command instructing the device to update the transmitter parameters values is received, in the device, when a device transmitter signal integrity for the signal communication is below a predetermined threshold.
