摘要： A method of manufacturing a perpendicular magnetic recording medium substrate is capable of reducing the waviness of all wavelength components and a recording medium is capable of reducing contact with a magnetic head to improve the flying stability of the magnetic head. The method includes two polishing operations. The first operation includes polishing a substrate having a Ni—P-based alloy underlayer with a first porous material that includes 0.1 wt % to 25 wt % of alumina, titania, silica, and zirconia abrasive while supplying a first slurry liquid including an organic or inorganic acid and a first abrasive to the underlayer of the substrate. The second operation includes polishing a surface of the underlayer polished in the first polishing with a second porous material while supplying a second slurry liquid including an organic or inorganic acid and a second abrasive with a grain diameter smaller than that of the first abrasive.

摘要： In a magnetic recording medium and magnetic recording medium manufacturing method, it is possible to easily separate a conjoined body without carrying out shape processing in a transfer master in order to separate a conjoined body, and without scratching the magnetic recording medium in a separating step. Moreover, it is possible to mass-produce the magnetic recording medium efficiently without increasing the size of a device. As the central portion of a transfer master is caused to bow convexly in an upward direction, in a condition in which a press receiving surface portion of the transfer master is restrained by a pressing surface of a pressing member, the outer periphery of a magnetic recording medium in a conjoined body is easily separated from a transfer receiving medium contact region of the transfer master in such a way that a predetermined gap is formed.

摘要： A system and method for magnetic transfer. A magnetic transfer device includes a plurality of pairs of magnetic field generating units that apply a magnetic field to a contact body which includes a master disk in close contact with a magnetic recording medium, wherein the master disk has a pattern of preformatted signals. The magnetic field generating units, falling within a specified length range, are moved in synchrony at a predetermined speed in the directions of the outer periphery while the contact body is caused to rotate by a rotation drive unit. The system and method provide a magnetic transfer method and a magnetic transfer device that, by reducing the area of magnetic field generating units that apply a transfer magnetic field, can reduce an attractive force (or repulsive force) between the magnets, and furthermore, shorten a processing time for the transfer.

摘要： A method of manufacturing a master disk for magnetic transfer is provided in which a pattern configuration does not change and burrs that require a polishing process are not generated. The method of manufacturing a master disk for magnetic transfer can include preparing a nonmagnetic body, forming a pattern of recessed parts on the nonmagnetic body, and forming a ferromagnetic material layer by depositing a ferromagnetic material on a surface of the nonmagnetic body having the pattern of recessed parts thereon. The method can further include forming a pattern of ferromagnetic material layers at the recessed parts by removing an excess portion of the ferromagnetic layer without using a mask. An etching rate of the nonmagnetic body can be larger than an etching rate of the ferromagnetic material layer in the operation of forming a pattern of ferromagnetic material layers at the recessed parts.
