摘要： A fine pattern which includes servo patterns, each constituted by servo elements, and groove patterns, each for separating adjacent data tracks, is formed on a substrate applied with a resist and placed on a rotation stage by scanning an electron beam on the substrate. While rotating the substrate in one direction, the electron beam is scanned so as to completely fill servo elements corresponding to a plurality of tracks one by one during one rotation of the substrate by X-Y deflecting the electron beam and vibrating back and forth in the radius direction. Each groove pattern is set as a line-up of a plurality of groove elements divided at a predetermined angle, and groove elements corresponding to the plurality of tracks following the writing of the servo elements are sequentially written by deflection scanning the electron beam largely in a circumferential direction during the same rotation.

摘要： When executing a magnetic transfer by bringing a master medium and a slave medium into close contact with each other and applying a transferring magnetic field, a permitted limit of the application direction of the transferring magnetic field is defined so that magnetic patterns can be accurately transferred. A slave medium 2 is previously initial DC magnetized in a track direction by applying a magnetic field to the slave medium in the track direction of a slave surface, and when executing a magnetic transfer by bringing the master medium 3 and the slave medium 2 into close contact with each other and applying the transferring magnetic field in the track direction of the slave surface, the application angle α of the transferring magnetic field is defined within a range of ±30° in a vertical direction with respect to the slave surface. Furthermore, the application angle of the transferring magnetic field is defined within a range of ±30° with respect to the track direction on a plane parallel to the slave surface.

摘要： The present invention provides a disk-shaped magnetic recording medium in which a servo signal for tracking is recorded as a preformat by a magnetic transfer method. This disk-shaped magnetic recording medium facilitates the manufacture of a master disk which carries information to be transferred. The disk-shaped magnetic recording medium permits the asymmetry of a regenerative signal of a servo signal for tracking which is recorded, facilitates the manufacture of a master disk which carries information to be transferred, and enables a servo signal for tracking to be recorded in a short time by use of a magnetic transfer method.

摘要： Deflecting means, for deflecting an electron beam in a radial direction and the circumferential direction, and blanking means, for shielding irradiation of the electron beam at portions other than drawing portions, are provided. While the disk is rotated unidirectionally, the electron beam is repeatedly deflected in a figure 8 pattern, in which the electron beam is deflected toward the next deflection initiation point in the radial direction at track edge portions, such that the deflected directions toward the inner periphery of the disk and toward the outer periphery of the disk intersect each other. Parallel scanning is performed alternately toward the outer periphery and the inner periphery of the disk. Elements of a transfer pattern, having lengths which are integer multiples of a reference value, are drawn by performing scanning a number of times equal to the integer that the reference value is multiplied by.

摘要： Information represented by a pattern of a magnetic layer formed on a master information carrier is magnetically transferred to a slave. An initial DC magnetic field is applied to the slave medium with the slave medium supported from one side thereof so that the other side of the slave medium is directly opposed to the magnetic field generator, and a transfer magnetic field is applied to the slave medium and the master information carrier held in close contact with each other by a holder, which covers both the sides of the slave medium/master information carrier assembly, with the magnetic field generator positioned to oppose both the sides of the slave medium/master information carrier assembly so that the magnetic field generated by the magnetic field generator is applied to the slave medium and the master information carrier through the holder.
