Abstract:
An information recording medium (100) includes (i) a first recording layer (L0 layer) having a first track and (ii) a second recording layer (L1 layer) having a spiral or coaxial second track sharing the rotation center with the first track. (iii) The first recording layer has a first point (point Bx) indicated by a first address. (iv) The second recording layer has a second point (point Dx) which can be defined according to a predetermined positional relationship (allowable area: 10) with respect to the first point (point Bx).
