Summary of the patent applications from Western Digital Technologies, Inc. on November 30th, 2023

Western Digital Technologies, Inc. has recently filed several patents related to various aspects of data storage devices and technologies. These patents cover areas such as semiconductor structures, digital signature verification, spin-orbit torque magnetic tunnel junction (SOT MTJ) devices, tape assembly implementation, disk coatings, emergency power-off procedures, motor control modes, lane selection based on thermal conditions, and lane detection and configuration.

Notable recent patent applications from Western Digital Technologies, Inc. include:

- A semiconductor structure with alternating layers of insulating and conductive materials, featuring stepped surfaces and a metal oxide etch stop layer. - A method for verifying the authenticity of a digital signature using elliptic curve cryptography (ECC) and authenticating the use of a message based on this verification. - An innovation aimed at improving the performance and stability of spin-orbit torque magnetic tunnel junction (SOT MTJ) devices by utilizing specific buffer and interlayer materials. - A simplified and efficient design for tape assembly in magnetic recording devices, involving mounting reels with hubs and flanges or flangeless hubs. - A disk for a magnetic recording apparatus with a substrate coated on both surfaces, where the maximum difference in thickness between the coating layers is determined by the square of the disk thickness. - A data storage device with two read-write heads and two disks, each controlled by separate actuators, and an emergency power-off procedure that retracts and parks the actuators before braking the spindle motor. - A data storage device with disks and a motor capable of operating in both PWM and linear modes, transitioning between the modes and compensating for a transition offset to move the disk heads to a target track. - Methods and systems for lane selection based on thermal conditions, where the number of lanes used for communication with the data storage device is reduced to control the thermal state. - Methods and systems for lane detection and configuration, automatically detecting the orientation of a cable connected to the data storage device and configuring the lane accordingly. - A storage system that stores data in a primary block and a secondary block, with data and its copy stored in both blocks along with parity bits for error protection, and the primary block lacking a header to increase error protection for the data.

In summary, Western Digital Technologies, Inc. has recently filed patents covering a range of innovations in data storage devices and technologies, including semiconductor structures, digital signature verification, SOT MTJ devices, tape assembly, disk coatings, emergency power-off procedures, motor control modes, lane selection based on thermal conditions, lane detection and configuration, and storage system designs.
