    摘要： Magnetic memories and methods are disclosed. A magnetic memory as described herein includes a plurality of stacked data storage layers to form a three-dimensional magnetic memory. Bits may be written to a data storage layer in the form of magnetic domains. The bits can then be transferred between the stacked data storage layers by heating a neighboring data storage layer, which allows the magnetic fields from the magnetic domains to imprint the magnetic domains in the neighboring data storage layer. By imprinting the magnetic domains into the neighboring data storage layer, the bits are copied from one data storage layer to another.

    摘要： A magnetic recording medium has a laminated magnetic structure with at least three magnetic layers, wherein the magnetic layers have decreasing intrinsic coercivity H0 with distance from the write head. The write field at the center of each magnetic layer is greater than that layer's H0. The magnetic layers have different compositions and/or thicknesses and thereby different values of H0. The alloys used in the middle and upper magnetic layers are relatively “high-moment” alloys that would not ordinarily be used in magnetic recording media because they have relatively low S0NR, but the overall S0NR of the laminated magnetic structure is improved because of the effect of lamination. The middle and upper magnetic layers can be made substantially thinner, which enables the magnetic layers to be located closer to the write head, thereby exposing each of the magnetic layers to a higher write field.

    摘要： A magnetic recording disk drive has an inductive write head and a heater to record data in laminated media on the recording disk. The laminated media, with at least two ferromagnetic layers separated by a nonmagnetic spacer layer, improves SNR. Each of the ferromagnetic layers can be formed of a material having an intrinsic coercivity capable of being written by a conventional inductive write head, but because of the desired lamination to increase SNR, the ferromagnetic layer farthest from the write head is exposed to a magnetic field less than its intrinsic coercivity and thus can not be written. To write to the laminated media, heat is directed to the lower ferromagnetic layer to reduce its intrinsic coercivity below the magnetic field to which it is exposed.

    摘要： A laser based inspection tool (LIT) for inspecting planar surfaces is described. In a preferred embodiment the LIT can simultaneously inspect both planar surfaces of disks for use in disk drives. In an embodiment of the invention, the incident beam is directed onto the surface to be inspected at an angle slightly offset from perpendicular so that the reflected beam is physically separated from the incident beam. Although slightly offset the reflected beam is routed back through the telecentric lens and scanner which are used for the incident beam. Preferably an aperture mask is placed in the path of the reflected beam and the incident beam to limit the cone of scattered light. Since the incident and reflected beams are physically separated, there may be an aperture for each beam, but the two masks may be physically connected. The aperture masks may also be used for alignment adjustments of the beams.

    摘要： A multiple data layer dye-based optical disk drive uses a disk with a light transmissive substrate onto which the laser light at a single wavelength is incident. The disk substrate supports at least two spatially separated data layers formed of dye material. The disk is either an air-gap structure wherein each data layer is supported on a separate substrate and the substrates are separated by an air-gap, or a solid structure wherein a solid light transmissive spacer layer separates the data layers. The invention makes use of the characteristic anomalous dispersion absorption band of certain dye materials, in which at a specific wavelength the dye material exhibits a high index of refraction and low extinction coefficient. This allows the first data layer (the one nearest the incident laser light) and intermediate data layers to exhibit both sufficient absorption when the laser is focused on those data layers and high transmissivity when the laser is focused on the last or farther data layers. The index of refraction of the dye-based data layers is selected to be significantly greater than the adjacent substrate and spacer layer to enhance the reflectivity, and the thickness of the data layers is selected to take advantage of the constructive interference effect caused by the reflection at those interfaces. In one embodiment of the invention the dye material for the data layers is a mixture of two different dyes that are not chemically reactive with one another and that retain their individual optical properties. This dye-based data layer exhibits anomalous dispersion absorption at two distinct wavelengths, thereby allowing disks recorded at one wavelength to be read by optical disk drives that use lasers operating at a lower wavelength.
