Information storage medium, record reproducing device, and record reproducing method

An information recording medium comprising:

• at least three recording layers comprising at least two recording layers that have PIC areas allocated therein, and at least one recording layer that has no PIC area allocated therein,
• wherein OPC areas are allocated to the at least three recording layers, and the OPC areas of the at least three recording layers are arranged in different radiuses,
• the PIC areas allocated to the at least two recording layers are allocated to the same radius, and
• the OPC area allocated to the at least one recording layer that has no PIC area partially overlaps with or is allocated in the radius to which at least one of the PIC areas allocated to the at least two recording layers is allocated.

An apparatus for recording and/or reproducing data on/from an information recording medium comprising at least three recording layers, the apparatus comprising:

• a pickup for recording and/or reproducing data with respect to the information recording medium;
• and
• a control unit for controlling the pickup to record and/or reproduce the data with respect to the information recording medium,
• wherein at least one recording layer comprises a permanent information and control data (PIC) area, at least two recording layers have no PIC area, OPC areas are allocated to the at least three recording layers, and the OPC areas of the at least three recording layers are arranged in different radiuses, and
• at least one of the OPC areas allocated to the at least two recording layers that have no PIC area is allocated in a radius to which the PIC area is allocated in the at least one recording layer comprising the PIC area, and at least one other OPC area is allocated to partially overlap the radius to which the PIC area is allocated in the at least one recording layer comprising the PIC area.
