摘要： An apparatus and associated method for reorienting the magnetic anisotropy of magnetic recording discs. A pallet that is moveable along a path of travel is also sized to selectively hold either a first magnetic recording disc of a first size or a second magnetic recording disc of a second size different than the first size. A first processing chamber in the path of travel is adapted for forming a soft underlayer (SUL) of magnetic material with non-radially oriented magnetic anisotropy on a substrate corresponding to one of the first and second magnetic recording discs. A second processing chamber in the path of travel downstream of the first processing chamber is adapted for selectively re-orienting the SUL's magnetic anisotropy via a magnetic source emanating a first magnetic field if the substrate corresponds to the first magnetic recording disc and emanating a different second magnetic field if the substrate corresponds to the second magnetic recording disc.

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： 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.
