CA 2472075
An optical disk includes a first information recording layer, and second to N-th information recording layers (with N being an integer of two or greater) that are arranged further toward the side from which laser light is irradiated than the first information recording layer and which are arranged in order from the side near the first information recording layer. The first information recording layer includes a read-only control data region, a first recording learning region for learning recording parameters to record data, and a first user data recording region for recording user data. When taking at least one of the second to N-th information recording layers as an i-th information recording layer (with i being an integer satisfying 2 ~ i ~ N), that i-th information recording layer includes an i-th recording learning region for learning recording parameters to record data in the i-th information recording layer, and an i-th user data recording region for recording user data. The first recording learning region and the i-th recording learning region are arranged at different radial positions, and the i-th recording learning region is arranged within a region of radial positions at which the control data region is provided.
