<P>PROBLEM TO BE SOLVED: To avoid excessive spread of a lost region lost upon development processing. Ž<P>SOLUTION: When a pattern for forming a concave part is drawn by irradiating a unit concave part forming region Ab2 having a rectangular shape in plan view regulated in a concavo-convex pattern forming layer on a base material corresponding to a second unit information region having a rectangular shape in plan view constituted of a non-recording region of an information recording medium with a beam for drawing while the base material is rotated, irradiation is performed so that a first beam irradiation ending position E20 to a right side region Ad including a near corner part of both end part regions Ad in the radial direction in the regions Ab2 is made near to a first beam irradiation starting position S20 in the base material rotated direction from a virtual extending line (a broken line Lv13) of a line connecting a second beam irradiation ending positions E12 to E19 to a central part region Ac in the radial direction in the region Ab2 when e.g. a left and upper region Ab2 of the two regions Ab2 whose corner parts are coming close to each other is irradiated with the beam.
