摘要： A magnetic memory element that has a stress-induced magnetic anisotropy. The memory element has a ferromagnetic free layer having a switchable magnetization orientation switchable, a ferromagnetic reference layer having a pinned magnetization orientation, and a non-magnetic spacer layer therebetween. The free layer may be circular, essentially circular or nearly circular.

摘要： An apparatus is disclosed for reducing disc deflection in response to the application of a non-operational mechanical shock to a disc drive. The disc drive comprises discs rotatable about a disc axis and each having an outer diameter. A circumferentially extending snubber is provided proximate a substantial portion of the outer diameter of each of the discs. The snubber includes a shroud portion immediately proximate the outer diameter of each disc and snubber arms which extend from the shroud portion in a direction toward the disc axis. The snubber limits deflection of the outer diameter of each disc in response to the application of a nonoperational mechanical shock to the disc drive.
