Patent number: 11615810Abstract: A hard disk drive enclosure base includes a non-uniform disk shroud surface extending from a top to a floor, the shroud surface including a first portion having a first radius and clearance along the circumference of the shroud surface and a second portion having a lesser second radius and clearance. The second portion of the shroud surface may be positioned at multiple locations where the drive form factor is especially constraining and in view of the need for a sufficient seal land surface for applying a gasket seal around the perimeter of the inner cavity of the base part. Widening the disk shroud clearance where possible can reduce the shear stress exerted at the disk edges thereby reducing the windage drag and associated disk spindle motor power consumption, especially in the context of helium-filled drives in which disk flutter is less of an issue.Type: GrantFiled: April 1, 2022Date of Patent: March 28, 2023Assignee: Western Digital Technologies, Inc.Inventors: Andre Chan, Yoshiyuki Hirono, Yuichi Arai

Patent number: 11598120Abstract: An electronic lockbox includes a latching apparatus that uses a rotary actuator with multiple positions to achieve multiple locking states. Multiple positions of the actuator are detected, using optical sensors. The locking mechanism includes an outer sleeve and an inner cylindrical barrel that are coupled with torsion springs. The lockbox has a shackle and a key bin that include latch pins which are retained by the inner barrel when in the locked state, and the barrel can be rotated to either release the shackle or to release the key bin that typically holds a building's key. During insertion of a latch pin into the rotatable barrel, the maximum torque imparted on a first spur gear by the torsion spring, at a maximum rotation angle of the rotatable barrel, is sufficient to rotate the barrel back to its neutral position after the latch pin has been fully inserted into the barrel, and is less than or equal to a back drive torque limit of a prime mover of the rotary actuator.Type: GrantFiled: November 29, 2019Date of Patent: March 7, 2023Assignee: SentriLock, LLCInventors: Scott R. Fisher, Alan F. Deardoff, Nancy C. Griffiths, Daniel C. Cambron, Matthew K. Caskey

Patent number: 11594247Abstract: Disclosed herein are sliders with at least one notch-cut in the trailing pad, methods of making them, and data storage devices comprising them. In some embodiments, a slider comprises a leading-edge surface, a trailing-edge surface, and an air-bearing surface (ABS) that includes a trailing pad situated closer to the trailing-edge surface than to the leading-edge surface, wherein the trailing pad comprises at least one notch-cut (e.g., two notch-cuts) in a trailing side of the trailing pad. The at least one notch-cut provides higher pressure at the recording head situated in the trailing pad and higher thermal flight control efficiency without a commensurate increase in touch-down power. As a result, the temperature around the recording head is lower than without the at least one notch-cut, thereby improving the lifetime of the recording head and data storage device.Type: GrantFiled: February 28, 2022Date of Patent: February 28, 2023Assignee: Western Digital Technologies, Inc.Inventors: Biao Sun, Weidong Huang
