  • Magnetically repositionable cassettes within a data storage drive
    Patent number: 11790946
    Abstract: The presently disclosed technology is directed to maximizing cleanliness, reliability, and space efficiency within a jukebox-style HDD, while minimizing overall cost of the HDD. In an effort to reduce the movement of a robotic arm assembly, cassettes within a jukebox-style HDD may be configured to be magnetically repositionable to replace some of the movement of the robotic arm assembly, without adding another significant source of potential mechanical failure within the HDD enclosure. Further, the overall number of moving parts is reduced, which may improve reliability of the HDD, as well as cleanliness within the HDD enclosure.

  • Idle power saving for actuator device
    Patent number: 11790947
    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.

  • Write and compare only data storage
    Patent number: 11782610
    Abstract: The presently disclosed technology is directed to combatting data theft, particularly of verified authentication data (or hashes thereof) such as login information, thumbprint data, digital signatures, identification numbers, and any other data that should be known to an accessor of stored data. The verified authentication data is initially saved for later comparison in a new type of memory, write-and-compare-only memory, where the data may be queried as to whether a to-be-verified value matches the stored verified value, but the stored and verified data is not read from the write-and-compare-only memory. This prevents a data breach by preventing the verified authentication data from being read by anyone, including those with access (whether legitimate or illegitimate) to any system connected to the write-and-compare-only memory.

  • Spin torque assisted magnetic recording media
    Patent number: 11769526
    Abstract: Magnetic recording media with a thermal spin injection layer that induces a spin injection in a magnetic recording layer in response to a thermal gradient in the thermal spin injection layer. The thermal spin injection layer may comprise an antiferromagnetic, a ferromagnetic, or a ferrimagnetic material that demonstrates a Spin Seebeck effect. In turn, when heating the magnetic recording media (e.g., with a near field transducer of a HAMR drive), the thermal gradient may be established in the thermal spin injection layer. A resulting spin torque field may assist in switching a magnetic domain in the magnetic recording layer by providing an assistive field to at least initiate switching of the magnetic domain. In turn, more reliable or efficient operation of a storage drive comprising the magnetic recording media may be realized.
