OPTICAL INFORMATION RECORDING MEDIUM, AND STAMPER FOR OPTICAL INFORMATION RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To prevent the loss of recording information in a recording area when the loss of address information occurs. SOLUTION: In an optical information recording medium 1 to which information can be rewritably optically recorded, grooves where address information modulated by a wobble is recorded are formed in a recording layer. A trial writing area A1 for performing trial writing to determine recording power and the recording area A2 for recording information are prepared. The relation between the amplitude W1 of the wobble in the trial writing area A1 and the amplitude W2 of the wobble in the recording area A2 is 'W1<=W2'.
