    摘要： Apparatus for, and a method of, duplicating magnetically recorded information by contact transfer from a master medium to a slave medium in the absence of a transfer field. The slave medium comprises a dilute concentration of magnetic particles productive of a demagnetization field that is negligible compared to an external magnetic field of the master medium in its contact-transfer zone. The absence of an appreciable demagnetization field in the slave medium enables the external magnetic field of the master medium to be virtually unopposed in effecting the magnetization of the slave medium.

    摘要： Apparatus is disclosed for the direct overwriting of an optical storage medium having a magneto-optical recording layer. The apparatus includes a condensing lens for focusing radiation from first and second radiation sources on a first and a second region respectively of the recording layer, wherein a region illuminated by the first radiation source is thereafter illuminated by the second radiation source. First and second magnets are provided. The first magnet is proximate the first radiation beam and has a first magnetic pole proximate the first region without contacting the storage medium. The second magnet is proximate the second radiation beam and has a magnetic pole opposite the first magnetic pole proximate the second region. The first magnet and the first radiation beam are selected to provide a first orientation of magnetic domains in the magneto-optical recording layer. The second magnet and the second radiation beam are selected to provide a second orientation of magnetic domains in the storage medium.

    摘要： A 3,000-10,000 angstrom thick cobalt-platinum (CoPt) magnetic film is deposited onto a chromium (Cr) or tungsten (W) overlayer on a substrate, or is deposited directly onto the substrate. The deposited film has an appreciable component of its C-axis, which is parallel to the [00.2] direction, lying in the plane of the film. The component of the C-axis lies in the plane of the film throughout the entire thickness of the CoPt film, and the resultant magnetic film has a coercivity from 1,300-2,000 oersteds, depending upon which, if any, overlayer is included.The method for producing the magnetic film of the invention teaches sputtering the overlayer onto a substrate maintained approximately at room temperature in an atmosphere of inert gas. After ajdusting the pressure of the gas and controlling the distance between the CoPt sputtering target and the substrate, CoPt is sputtered such that the depositing Co and Pt atoms are thermalized while traversing the distance between the target and the substrate.The film as deposited is magnetically isotropic in the plane, and may configured as a permanent magnet having a resultant magnetization in the plane by exposure to an external magnetizing field oriented along the film plane.
