摘要： A magnetic recording medium includes a highly permeable magnetic layer proximal to a recording layer. During recording, the permeable magnetic layer modifies the recording field from a recording head to produce consistently shaped recording transitions with a significant perpendicular component. The transitions are consistently shaped even though the distance between the recording head and the surface of the medium may change. Transitions so formed result in a reduction of noise from the medium surface roughness. The permeable magnetic layer further reduces noise caused by stray dipole fields.

摘要： A master information carrier comprises a substrate whose surface has an embossed pattern corresponding to an information signal. At least a surface of the protruding portion of the embossed pattern is made of a ferromagnetic material. A method for writing an information signal into a sheet or disk magnetic record medium with a ferromagnetic thin film or coating is performed by putting the surface of the magnetic record medium into contact with the master information carrier so as to write a magnetized pattern corresponding to the embossed pattern of the master information carrier into the magnetic record medium.

摘要： A method of making a polycrystalline structure film includes causing metallic atoms and molecules of compound to deposit over the surface of a substrate. When the metallic atoms and the molecules of the compound are simultaneously deposited on the substrate, fine and smallest metallic nucleation sites can be formed over the surface of the substrate at a higher density per unit area. Subsequent deposition of metallic atoms enables generation of fine and smallest crystal grains consisting of the metallic atoms.

摘要： A data storage device including a substrate, a data storage layer on the substrate, and a spin-polarized electron source. The data storage layer comprises a fixed number of atomic layers of a magnetic material which provide the data storage layer with a magnetic anisotropy perpendicular to a surface of the data storage layer. A data magnetic field is created in the data storage layer. The data magnetic field is polarized either in a first direction corresponding to a first data value or in a second direction corresponding to a second data value. Data is stored in the data storage layer by providing a spin-polarized electron having an electron magnetic field with a direction of polarization corresponding to one of the first and the second data values, the electron having a wavelength “characteristic” of unpaired electrons in the data storage layer which cause the magnetic moment of the material, and directing the spin-polarized electron at the data magnetic field to impart the direction of polarization of the electron magnetic field to the data magnetic field. Data is read from the data storage layer by directing the spin-polarized electron at a second wavelength at the data magnetic field and detecting a deflection or attraction of the spin-polarized electron by the data magnetic field. Alternatively, data is read from the data storage layer by directing the spin-polarized electron at the data magnetic field so that the magnetic medium produces a secondary electron and then detecting certain characteristics of the secondary electron.

摘要： A magnetic recording medium comprising a thin magnetic metal film of which the thickness and remanent magnetization are smaller than ever and optimized to match the characteristics of the MR read head used with the recording medium. The thin magnetic metal film is formed on a nonmagnetic substrate and has a remanent magnetization and film thickness product Mrnullnull of 1 to 5 memu/cm2. Owing to this product Mrnullnull, a signal recorded on the magnetic recording medium can be reproduced with no distortion in a region where the MR read head maintains its linearity.
