    摘要： A two-layer recording type optical disk capable of realizing stable recording and reproduction without being affected by another recording layer and an optical disk apparatus for the two-layer recording type optical disk are provided. In layouts of various areas in the optical disk, a position where a border between a recorded part and an unrecorded part is formed on one recording layer is set so that the position is always separated from a position where a border between a recorded part and an unrecorded part is formed on another recording layer by a predetermined clearance amount. Moreover, to a recording layer farther from an incident surface, test recording or data recording is always performed through a recorded part on a closer recording layer.
