Patent number: 11577888Abstract: A cap and container assembly includes a container having a base and a side wall extending upward from the base. The base and the side wall define an interior, and the side wall defines an opening leading to the interior. A cap moves with respect to the container between an opened position in which the opening is exposed, and a closed position in which the cap covers the opening. A tab projects outward from the cap and has a bottom surface. A spacer projects from the container side wall at a location beneath the tab when the assembly is in the closed position. The spacer bends inward towards the container in response to application of a sufficient force, to move from a locked position that blocks the bottom surface of the tab, to an unlocked position to expose at least a portion of the bottom surface of the tab.Type: GrantFiled: October 6, 2020Date of Patent: February 14, 2023Assignee: CSP Technologies, Inc.Inventors: Jean-Pierre Giraud, Herve Pichot, John Belfance, Mark Ostrowski, Michael Bucholtz, Joseph W.

Patent number: 9576595Abstract: A mounting surface of a read/write head is prepared to receive an epitaxial layer. The mounting surface is proximate a waveguide of the read/write head, and the waveguide is configured to receive an optical output from the epitaxial layer. The epitaxial layer is transfer printed on to the mounting surface. The mounting surface maintains a vertical alignment between the optical output and the waveguide. The epitaxial layer is processed to form a laser integrated with the read/write head.Type: GrantFiled: November 19, 2015Date of Patent: February 21, 2017Assignee: SEAGATE TECHNOLOGY LLCInventors: Roger L.

Patent number: 9378757Abstract: The disclosed methods enable the production of plasmonic near-field transducers that are useful in heat-assisted magnetic recording. The plasmonic near-field transducers have an enlarged region and a peg region. The peg region includes a peg region in proximity to an air-bearing surface above a recording medium and also includes a flared region between and in contact with the enlarged region and the peg region. The flared region can act as a heat sink and can lower the thermal resistance of the peg portion of the near-field transducer, thus reducing its temperature.Type: GrantFiled: March 7, 2013Date of Patent: June 28, 2016Assignee: SEAGATE TECHNOLOGY LLCInventors: Yongjun Zhao, Dongsung Hong, Lijuan Zou, Mark Ostrowski
