PROBLEM TO BE SOLVED: To provide an optical stuck disk which causes no warpage even if a printing layer is formed between stuck surfaces. SOLUTION: This disk is constituted by forming a recording layer 2 on the stuck surface of at least one disk substrate 1 of a pair of one-side disk substrates 1, 5 in which the stuck surfaces are adhered together while facing to each other. In such a case, a hardening and contracting layer such as the printing layer 4 is formed on one stuck surf ace of a pair of the one-side disk substrates 1, 5 and a compensating layer 6 for correcting the warpage of the stuck surface due to contraction of the hardening and contracting layer is formed on at least one of a pair of the one-side disk substrates 1, 5. |
