International Classification:
G11B 5/82
C23C 14/34
C23C 14/34
US Classification:
360135, 20419215, G9B 5293
Abstract:
A magnetic storage medium according to one embodiment includes a substrate; a first oxide magnetic layer formed above the substrate; a second oxide magnetic layer formed above the first oxide magnetic layer; an exchange coupling layer formed above the second oxide magnetic layer, the exchange coupling layer comprising an oxide; and a magnetic cap layer formed above the exchange coupling layer. A method according to one embodiment includes forming a high Ku first oxide magnetic layer above a substrate by sputtering; forming a low Ku second oxide magnetic layer above the first oxide magnetic layer by sputtering; forming an exchange coupling layer of CoCrPt-oxide above the second oxide magnetic layer; and forming a magnetic cap layer above the exchange coupling layer. Additional systems and methods are also presented.

System And Method For Dynamic Verification Of Trusted Applications
US Patent:
2022017, Jun 9, 2022
Filed:
Dec 7, 2020
Appl. No.:
17/113980
Inventors:
- Suwon-si, KR
Michael C. Grace - Sunnyvale CA, US
Chu Ly Tran - San Jose CA, US

International Classification:
G06F 21/57
G06F 9/4401
G06F 9/4401
Abstract:
An electronic device, a method, and a non-transitory, computer-readable medium storing instructions for dynamically verifying trusted applications (TAs) during a boot sequence. The electronic device includes a memory and a processor operably connected to the memory. The processor executes instructions stored in the memory to cause the electronic device to initialize a kernel boot sequence in response to confirming that executable codes for booting the electronic device are from a trusted binary and then verify one or more registered TAs during the kernel boot sequence. Completion of the kernel boot sequence is based on verification results of the set of registered TAs.
Patterned Perpendicular Magnetic Recording Medium With Ultrathin Noble Metal Interlayer
US Patent:
2015030, Oct 22, 2015
Filed:
Apr 17, 2014

Assignee:
HGST Netherlands B.V. - Amsterdam
International Classification:
G11B 5/738
G11B 5/66
G11B 5/66
Abstract:
A bit-patterned media (BPM) magnetic recording disk has a cobalt (Co) alloy recording layer (RL), a ruthenium (Ru) containing underlayer (UL), and a noble metal film (NMF) as an interlayer between the RL and the UL. The RL is preferably oxide-free and is a Co alloy, like a CoPtCr alloy, with a hexagonal-close-packed (hcp) crystalline structure with its c-axis oriented substantially perpendicular to the plane of the RL. The NMF is an element from the Pt group (Pt, Pd, Rh, Ir) and Au, or an alloy of two or more of these elements, and has a thickness less than 3.0 nm, preferably between 0.3 and 1.0 nm. The NMF does not interrupt the epitaxial growth of the RL and has little to no effect on the distribution of the RL c-axis orientation. The NMF increases the coercivity (Hc) and perpendicular magnetic anisotropy constant (K) of the RL.
