    摘要: An information recording medium of the present invention includes N information layers on a substrate (1), where N is an integer of 2 or more. Information is recorded/reproduced by irradiating each of the information layers (11, 12) with a laser beam (4). When the N information layers are referred to as a first information layer to an N-th information layer sequentially from the opposite side to a laser beam incident side, the L-th information layer included in the N information layers includes at least a recording layer (135) capable of undergoing a phase change through laser beam irradiation, a reflective layer (132), and a transmittance adjusting layer (131) in this order from the laser beam incident side, where L is an integer satisfying 2≦L≦N.

    摘要: A method for appropriately performing initialization of an optical information recording medium is provided, in which an initialization process is prevented from stopping so that yield from manufacturing the optical information recording medium is improved. In the initialization of an information layer with a burst cutting area (hereinafter referred to as “BCA”), at least one of the initialization conditions including a laser power, a linear speed, and a focal point of the laser beam for the information layer is changed between the BCA region and a data area that is an area for recording and reproducing information. In the initialization of an information layer without the BCA, at least one of the initialization conditions including a laser power, a linear speed, a focal point of the laser beam for the information layer and a feed pitch is changed between the area corresponding to the BCA and the area corresponding to the data area.
