摘要:
An apparatus may include a composite soft underlayer and a perpendicular magnetic recording layer overlying the composite soft underlayer. The composite soft underlayer may include a growth template layer, a negative magnetic anisotropy layer overlying the growth template layer, and a magnetically soft layer overlying the negative magnetic anisotropy layer. In some embodiments, the negative magnetic anisotropy layer includes a plurality of grains, and substantially all the grains have negative magnetic anisotropy along an axis substantially perpendicular to a major plane of the composite soft underlayer. In some embodiments, the negative magnetic anisotropy layer includes a thickness of less than or equal to about 3 nm.

An attachable monitoring device includes a battery unit, a wiring board unit and a physical condition sensor and an adhesive. The battery unit includes a top surface, a bottom surface and a plurality of side surfaces connecting the top surface and the bottom surface. The wiring board unit covers the top surface, the bottom surface and one of the side surfaces and electrically connected to the battery unit. The wiring board unit includes a printed antenna printed on a first outer surface of the wiring board unit. The physical condition sensor is disposed on a second outer surface of the wiring board unit opposite to the first outer surface. The physical condition sensor includes a sensing region for contacting a user to detecting a physical-condition signal of the user. The adhesive is disposed on the wiring board unit for being attached to the user.
摘要:
Epitaxial ferroelectric and magnetic recording structures having graded lattice matching layers are disclosed. A single crystal material such as Si may be used as a substrate material upon which the graded lattice matching layers are deposited. The lattice matching layers may comprise metals and metal alloys, or may comprise oxides doped with selected elements or deposited under different oxygen pressures. A recording layer, such as ferroelectric lead zirconium titanate or a magnetic Fe/Pt multilayer structure, is deposited on the graded lattice matching layers.

摘要:
Various magnetic stack embodiments may be constructed with a soft magnetic underlayer (SUL) having a first thickness disposed between a substrate and a magnetic recording layer. A heatsink may have a second thickness and be disposed between the SUL and the magnetic recording layer. The first and second thicknesses may each be tuned to provide predetermined thermal conductivity and magnetic permeability throughout the data media.
摘要:
A position-bias compensation method, applied to a three-dimensional image interactive system, includes steps of: displaying a three-dimensional image and setting a trigger position in a preset interactive coordinate system according to a default position of a user; obtaining a position-bias of a user's position from the default position; and resetting the trigger position according to the position-bias.
