ABSTRACT:
Data is recorded on an optical disc using a combination of a user data area where user data is recorded, a control data area for reproduction provided on an inner radius side of the user data area, and an outer guard zone provided on an outer radius side of the user data area as a unit of one recording operation. In this configuration, a track pitch TP of the optical disc is greater than or equal to 0.3 μm and smaller than or equal to 0.4 μm, and the width of the outer guard zone along a radius direction of the optical disc is greater than or equal to a value of (100×TP) and smaller than or equal to a value of (125×TP).
