Information recording medium, information recording device and method

摘要

A disc-shaped information recording medium includes a first recording layer (L0 layer) having (I) a first trial write area ( 101 P- 1 ) for trial write of first trial write information for calibration of the laser beam along the first track path (TP 1 ) from the inner circumference toward the outer circumference and (II) a first recording area for recording the first recording information along a first track path (TP 1 ), in this order from the inner circumference side. Furthermore, the disc-shaped information recording medium includes a second recording layer (L1 layer) having (I) a second trial write area ( 101 P- 2 ) for trial write of second trial write information for calibration of the laser beam along the second track path (TP 2 ) from the outer circumference toward the inner circumference and (II) a second recording area for recording the second recording information along a second track path (TP 2 ), in this order from the inner circumference side.
