Patent number: 11881235Abstract: The present disclosure relates to a magnetic recording head having an exchange biased leading shield or leading edge shield (LES). The LES is a bilayer structure. One or more layers are coupled below the LES such that the LES is disposed between the main pole and the one or more layers. The one or more layers exchange bias the LES such that the upper layer of the LES has a magnetization parallel to the magnetization of the trailing shield. The lower layer of the LES has a magnetization that is antiparallel to the magnetization of the upper layer of the LES. The one or more layers set the preferred direction for the lower layer of the LES and sets the LES as a two-domain state without relying upon the anisotropy field (Hk) of either the upper or lower layers of the LES.Type: GrantFiled: February 22, 2022Date of Patent: January 23, 2024Assignee: Western Digital Technologies, Inc.Inventors: Alexander Goncharov, Zhanjie Li, Terence T.

Patent number: 11862207Abstract: The present disclosure generally relates to data storage devices, and more specifically, to a magnetic media drive employing a magnetic recording head. The head includes a main pole, a trailing shield, and a MAMR stack including at least one magnetic layer. The magnetic layer has a surface facing the main pole, and the surface has a first side at a media facing surface (MFS) and a second side opposite the first side. The length of the second side is substantially less than the length of the first side. By reducing the length of the second side, the area to be switched at a location recessed from the MFS is reduced as a current flowing from the main pole to the trailing shield or from the trailing shield to the main pole. With the reduced area of the magnetic layer, the overall switch time of the magnetic layer is decreased.Type: GrantFiled: July 20, 2022Date of Patent: January 2, 2024Assignee: Western Digital Technologies, Inc.Inventors: Venkatesh H Chembrolu, Muhammad Asif Bashir, Petrus Antonius Van Der Heijden, Terence T.

Patent number: 11028690Abstract: A technique facilitates detection and analysis of constituents, e.g. chemicals, which may be found in formation fluids and/or other types of fluids. The technique comprises intermittently introducing a first fluid and a second fluid into a channel in a manner which forms slugs of the first fluid separated by the second fluid. The intermittent fluids are flowed through the channel to create a mixing action which mixes the fluid in the slugs. The mixing increases the exchange, e.g. transfer, of the chemical constituent between the second fluid and the first fluid. The exchange aids in sensing an amount of the chemical or chemicals for analysis. In many applications, the intermittent introduction, mixing, and measuring can be performed in a subterranean environment.Type: GrantFiled: July 9, 2018Date of Patent: June 8, 2021Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Farshid Mostowfi, Ronald E.
