PURPOSE:To carry out high-density recording especially with the error rate reduced by interposing an adhesive resin layer between a recording layer and a transparent polymer protective layer in a specified manner. CONSTITUTION:A layer of the transparent adhesive resin having -90 to +60 deg.C glass transition point is interposed between a recording layer and a transparent polymer protective layer in 0.1-50 mum thickness. The adhesive resin layer is previously provided on one between the recording layer and transparent polymer protective layer, and both layers are placed in <=50 mmHg vacuum and then firmly attached to each other. When the glass transition point exceeds +60 deg.C, the sensitivity of the recording layer is adversely affected, and the recording layer is peeled when bent or dropped at <-90 deg.C. Consequently, high-sensitivity and high-density recording is carried out. |
