    摘要: An information recording medium (100) includes: a first recording layer (107); a semitransparent reflective film (108) to reflect at least one portion of laser light for recording with which the first recording layer is irradiated; a second recording layer (207) which is irradiated with the laser light for recording through the first recording layer and the semitransparent reflective film; and a reflective film (208) to reflect the laser light for recording with which the second recording layer is irradiated, thermal conductivity from the second recording layer to the reflective film when the second recording layer is irradiated with the laser light for recording being substantially equal to thermal conductivity from the first recording layer to the semitransparent reflective film when the first recording layer is irradiated with the laser light for recording

    摘要: A groove track and a land track are alternately and spirally formed on an information recording medium. On the land track neighboring the groove track, pre-information indicating position information of a track on a disc is formed as a prepit. On the information recording medium, an embossed area is formed so that information about a copyright and for preventing an illegal copy cannot be rewritten. In the embossed area, an embossed configuration including a pit and a space of predetermined depths is formed. The prepit in the embossed area is formed so that the prepit has an optimized configuration according to a pit length and a space length in the embossed area which the prepit neighbors. Consequently, interference between the embossed configuration and the prepit can be prevented even in a case that the prepit is formed in addition to the embossed configuration in the embossed area.

    摘要: A recording layer close to a disc surface is divided into at least two recording areas, a main information recording area D1A and an auxiliary information area (BCA) D1C. Grooves are formed in the main information recording area D1A. Marks M are formed in barcode form representing identifying information in the auxiliary information recording area (BCA) D1C. Track grooves G1 or prepits are formed in the recording layer of the auxiliary information recording area (BCA) D1C and have a depth smaller than that of the groove formed in the main information recording area D1A.
