摘要： On an information recording medium, a first region where first recording regions that are long in a radial direction are disposed at a predetermined pitch with first non-recording regions in between is provided in a preamble pattern region. A second recording region that connects first recording regions that are adjacent in a direction of rotation is provided in the first region. A second non-recording region that is longer in the direction of rotation than a length in the direction of rotation of the first non-recording regions at corresponding same-pattern-radius positions is provided at a position where a read of servo data is carried out following the first region.

A drawing beam is intermittently irradiated N times onto a generally belt-shaped exposure area extending in a direction of rotation of the substrate from one end to the other end of the belt-shaped exposure area in the direction of rotation of the substrate, the belt-shaped exposure area being defined within a formation region, in which one of the convex or concave portions is to be formed, to thereby irradiate the drawing beam onto N generally belt-shaped irradiation areas extending in the direction of rotation of the substrate.

摘要： An energy beam irradiating apparatus includes a substrate holder, a moving stage, an energy beam irradiating mechanism, and a control unit. A disc-like substrate is attached to the substrate holder which includes a holder main part on which the disc-like substrate is mounted and a pressing plate, the disc-like substrate being held between the holder main part and the pressing plate with a formation region of an irradiation pattern on the disc-like substrate and a partial region of at least one of an outer edge and an inner edge of the disc-like substrate being exposed. The moving stage moves the substrate holder. The energy beam irradiating mechanism irradiates a surface of the disc-like substrate attached to the substrate holder with an energy beam. The control unit causes the moving stage to move based on a movement pattern with a reference point set in advance on the moving stage as a reference so that an irradiation pattern is formed on the surface of the disc substrate by irradiation with the energy beam. During formation of the irradiation pattern, the control unit calculates a center of the disc-like substrate based on at least one part of an outline of the exposed outer edge or inner edge of the disc-like substrate and sets the calculated center as the reference point.
