摘要

An optical recording and reproduction medium in which pits corresponding to recording information are formed along a recording track, wherein auxiliary pits are formed in at least a portion of the spaces between adjacent pits along the recording track direction; when the pit depth is d1 and the auxiliary pit depth is d2, then d1>=d2 is obtained; and both edges of the auxiliary pits along the recording track direction are shaped as simple convex curves.
