  • Publication number: 20150348764
    Abstract: Various embodiments provide a substrate carrier configured to rotatably carry at least one substrate through a plurality of processing stations. The substrate carrier includes an integrated heater for heating a first side of the substrate while the second side of the substrate undergoes one or more manufacturing processes at each of the plurality of processing stations, e.g., to promote the desired growth of HAMR media. This can result in the elimination of one or more processing stations, thereby realizing cost savings, decreased substrate processing time, as well as a reduced area within which a substrate processing system can be implemented.

  • Patent number: 5736020
    Abstract: A target assembly for use in forming a protective overcoat in a magnetic recording medium is described. The assembly includes a centrally positioned target with inner and outer magnetic means adjacent the target. A sputtering shield is positioned between the target and the medium for controlling the amount and angle of material deposition on the medium. The assembly is effective to deposit an overcoat having a greater thickness in the inner landing zone of the medium than in the outer data zone. A method of using the assembly is also disclosed.

  • Patent number: 5714044
    Abstract: A method for forming an overcoat having first and second layers in a magnetic recording medium is described. The first overcoat layer is deposited in a first sputtering chamber where the magnetic means for confining target plasma in the chamber are oriented to retain magnetic-field confinement about the target surface and to produce magnetic field lines between directly confronting portions of the confronting sputtering targets. The second overcoat layer is deposited under a nitrogen-containing atmosphere.

  • Patent number: 5693197
    Abstract: A method of producing a magnetic recording medium by sputtering a layer onto a substrate by DC-magnetron sputtering from a target while exposing the target to an RF signal is described. The RF signal is effective to extend the target utilization without significantly decreasing the sputtering rate. Also disclosed is an apparatus for use forming a medium in accordance with the method of the invention.

  • Patent number: 5569533
    Abstract: A longitudinal magnetic recording medium formed on a non-metallic substrate and a method of forming the medium is disclosed. A sublayer formed of a chromium alloy having a thickness between 3-50 .ANG. is deposited on the substrate, followed by a chromium-based underlayer. A cobalt-based magnetic recording layer is sputtered over the underlayer. The medium is characterized by improved coercivity, HF signal amplitude and signal-to-noise ratio.

  • Patent number: 5512150
    Abstract: A target assembly for use in fabricating magnetic recording media is described. The target assembly has inner and outer concentric targets for sputter depositing on a substrate first and second layers having different compositions. Disposed adjacent each target is a magnetic means, and at least one which is reversible in magnetic-pole polarity. One polarity produces a magnetic flux sufficient to ignite a sputtering plasma in the inner target only, when power is supplied to the inner target at a preselected level. The opposite polarity produces a magnetic flux sufficient to ignite a sputtering plasma in the outer target only, when power is supplied to the outer target at a preselected level.

  • Patent number: 5174880
    Abstract: A target assembly is provided having a circular flat target with an inner ring and an outer ring extending from the sputtering surface. A ferromagnetic outer pole member surrounds the target and the outer ring. A ferromagnetic inner pole member is surrounded by the target and the inner ring. A ferromagnetic backing member is positioned against the base surface of the target and has an outer portion positioned against the outer pole member, and an inner portion positioned against the inner pole member. These are positioned relative to the source of the magnetic field for conducting flux in a first path through the outer portion and the outer pole member, across the sputtering surface between the outer and inner rings, and through the inner pole member and inner portion. The backing member further includes a shunt portion intermediate between and magnetically spaced from the inner and outer portions.
