Abstract: Systems, devices, and methods may use input/output (I/O) apparatus and an optical switching medium to switch, or route, optical data signals. The optical switching medium may include a plurality of optical switching regions. The I/O apparatus may transmit optical data signals to and receive optical data signals from the optical switching medium to provide switching functionality.

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 hard disk drive including a base deck with a base member and side walls extending from the base member. The side walls include a non-metallic material and include a structure made from the non-metallic material. The structure is arranged to dampen vibration. The side walls can be formed using an additive manufacturing process.

Abstract: 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).

Abstract: 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.
