Patent number: 11875830Abstract: A data storage device (DSD) includes a base-deck, a disc above the base-deck, and a shaft extending perpendicular from the base-deck. The DSD also includes a head stack assembly (HSA) including a head gimbal assembly having a load beam and a head at a first end of the HSA. The head interacts with a surface of the disc. The HSA also includes a second end movably mounted on the shaft. The DSD additionally includes an elevator that linearly moves the HSA along the shaft to adjust a distance between the load beam and the surface of the disc in response to receiving a feedback signal associated with the interaction of the head with the surface of the disc. The feedback signal is one of a plurality of feedback signals employed by the elevator to adjust the distance between the load beam and the surface of the disc.Type: GrantFiled: April 25, 2022Date of Patent: January 16, 2024Assignee: Seagate Technology LLCInventors: Matthew Aaron Carper, Anil J.

Patent number: 11631431Abstract: Apparatus and method for transferring data in a data storage system, such as but not limited to a hard disc drive (HDD). An optical link is provided between an analog front end (AFE) of a data storage device controller circuit (SOC) and a preamplifier/driver circuit (preamp) mounted to a rotary actuator to transfer an analog domain signal. A selected component is extracted from the signal using a modulation element such as a micro-resonance ring (MRR) or a Mach-Zehnder Interferometer Modulation (MZM) device. The extracted component is forwarded to a processing circuit to facilitate a transfer of data between a local memory and a non-volatile memory (NVM). The optical link includes a flexible portion in a flex circuit affixed to the rotary actuator and which supports the preamp. Multiplexed read, write, and power control signals are concurrently transmitted via the optical link. The link can concurrently service multiple head-disc assemblies (HDAs).Type: GrantFiled: July 1, 2022Date of Patent: April 18, 2023Assignee: Seagate Technology LLCInventors: Kevin A. Gomez, Aditya Jain, Anil J. Reddy, Todd Michael Lammers

Patent number: 11335373Abstract: 3D optical data storage refers to forms of optical data storage in which information can be recorded and/or read with 3D resolution. 3D optical media are generally limited in areal density by the diffraction limit of laser light used to read and/or write data to and/or from the optical media. It is thus advantageous to find ways to store data on 3D optical media with a spot size below the diffraction limit of an associated laser reader to further increase areal density of the optical media. A hybrid approach that utilizes plasmon technology to access a surface layer of the 3D optical media with an extremely small spot size and photon technology to access interior layers of the 3D optical media with a larger spot size may substantially increase overall data density of the 3D optical media.Type: GrantFiled: February 22, 2021Date of Patent: May 17, 2022Assignee: SEAGATE TECHNOLOGY LLCInventors: Krishnan Subramanian, Aditya Jain, Riyan Alex Mendonsa, Anil J.
