摘要： A magnetic recording medium is provided, which includes a recording layer formed in a concavo-convex pattern to achieve high areal density and can ensure good recording and reproduction characteristics so as to provide high reliability. The magnetic recording medium has a substrate and a recording layer formed in the predetermined concavo-convex pattern over the substrate. The recording layer has a non-recording element and recording elements. The non-recording element is formed as convex portion of the concavo-convex pattern at an outer circumferential end and/or an inner circumferential end. The recording elements are formed as convex portions of the concavo-convex pattern in a region other than a region where the non-recording element is arranged. The magnetic recording medium further has a non-magnetic material with which concave portions of the concavo-convex pattern are filled and which covers the non-recording element, and a protective layer formed over the recording layer and the non-magnetic material.

摘要： A magnetic recording medium having a recording layer formed in a concavo-convex pattern, which can allow a head to have stable flying characteristics. The recording layer is formed in a concavo-convex pattern, and concave portions of the concavo-convex pattern of the recording layer are filled with a non-magnetic material. The relationship of S≦3.6×R holds, when R represents a concavo-convex ratio obtained by dividing an area of convex portions in a surface by an area of the concave portions in the surface, and S represents a difference in height between a concavity and a convexity of the surface. In the magnetic recording medium, an arithmetical mean deviation of the assessed profile of the surface is limited to 0.3 nm or more.

摘要： A highly reliable magnetic recording medium is provided which has a recording layer formed in a concavo-convex pattern and wherein the recording layer is unlikely to cause a change in magnetic properties. The magnetic recording medium includes a substrate, a recording layer formed in a predetermined concavo-convex pattern over the substrate, convex portions of the concavo-convex pattern serving as recording elements; and a filler portion filling a concave portion between the recording elements. The filler portion comprises a metal-based main filler material and oxygen. Oxygen is unevenly distributed in the filler portion so that the ratio of the number of oxygen atoms to the total of the number of atoms of the main filler material and the number of oxygen atoms is greater in an upper surface portion of the filler portion than in a lower portion of the filler portion.

摘要： A method for manufacturing magnetic recording media is provided, by which a magnetic recording medium that has a recording layer formed in a concavo-convex pattern, a sufficiently flat surface, and good recording/reproducing properties can be manufactured. The method includes the steps of: depositing a first filling material over a workpiece to cover recording elements formed as convex portions of the concavo-convex pattern, and to fill at least part of a concave portion; depositing a detection material over the first filling material; depositing a second filling material over the detection material; and irradiating a surface of the workpiece with a process gas to flatten the surface. In the flattening step, a component of the detection material removed from and flying off the workpiece is detected to stop the irradiation with the process gas based on a result of detecting the component of the detection material.

摘要： A method for manufacturing a magnetic recording medium is provided, by which a magnetic recording medium having a recording layer formed in a concavo-convex pattern, a sufficiently flat surface, and high recording and reproducing precision is efficiently manufactured. In a non-magnetic material filling step, a non-magnetic material is deposited over a recording layer formed in a predetermined concavo-convex pattern over a substrate to fill concave portions of the concavo-convex pattern with the non-magnetic material. In a flattening step, an excess part of the non-magnetic material above the recording layer is removed by dry etching, to flatten surfaces of the recording layer and the non-magnetic material. Processing conditions are set so as to substantially equalize an etching rate of the non-magnetic material with an etching rate of the recording layer with respect to the dry etching in the flattening step.

A filler for filling the concave portions is deposited over the surface of an object to be processed, the object being provided with a concavo-convex pattern. A cladding is further deposited over the filler. Then, an excess part of the filler and the cladding above the surface of the object are removed for flattening, by using a dry etching method having a lower etching rate to the cladding than to the filler.

摘要： Liquid nitrogen is filled in a low temperature vessel; an ejector that sucks liquid nitrogen by blowing a cooling agent (liquid or gas) such as low temperature helium gas or liquid helium of pressure higher than in the space within the vessel is disposed in the vessel; the liquid nitrogen blown with the cooling agent is cooled by the cooling agent to become fine particles of solid nitrogen which fall down; and gas in a space of the vessel is discharged out of the vessel so as to maintain the pressure of the space higher than the atmospheric pressure. A gaseous phase of liquid nitrogen in an adiabatic vessel is depressurized to vaporize nitrogen in a liquid phase so that a temperature of the nitrogen is reached to the triple point of nitrogen by lowering temperature thereby and solid nitrogen is produced by keeping at the triple point, and that the produced solid nitrogen is transformed into slush by stirring the content of the adiabatic vessel. In a method for cooling a super conductive body in which a material showing a state of super conductance in the vicinity of the temperature of liquid nitrogen or of the temperature liquid nitrogen and solid nitrogen coexist is used, a method for cooling a super conductive body characterized in that the super conductive body is immersed in slush nitrogen held in an adiabatic vessel, and that the body is contacted with slush nitrogen to cool.
