Abstract: PROBLEM TO BE SOLVED: To provide an optical disk which can have excellent reproduction characteristics by suppressing the quantity of variation of reproduction output. SOLUTION: The optical disk D1 which has a transparent information readout layer 8 thinner than its support base board 2 is so set that the quantity of variation of birefringence of one round in the disk rotating direction among birefringent components of the information readout layer which is obtained by double-path measurement is <=±20 nmpp. In this case, the variation quantity of the birefringence has two cycles in one round in the disk rotating direction. Further, the optical disk is formed by bonding a circular transparent sheet whose variation quantity of birefringence in the circumferential direction obtained by the double-path measurement is <=±20 nmpp to a support base disk thicker than the sheet having the sheet as a readout layer. Consequently, excellent reproduction characteristics are obtained by suppressing the variation quantity of the reproduction output.
