A read-once record medium includes a data substrate having a control data zone and a data zone with pre-record data. In addition, a sensitive layer is disposed above the data substrate and a refractive layer is disposed above the sensitive layer. An adhesive layer is disposed above the refractive layer and a transparent substrate is disposed above the adhesive layer. As a result, the structure of the sensitive layer or the data substrate will be destroyed when laser beams with a specified power a emitted from an optical storage device pass through the data substrate and focus on the sensitive layer. The laser beams will be reflected by the sensitive layer and cannot be recognized by the optical storage device.
