摘要：
A single-sided double layer disc comprises a first access layer, a second access layer, a bonding layer, and a protective layer. The first and second access layers are used for allowing a driving device to access the disc. The second access layer includes a second substrate having a second coating surface, a reflective layer laminated on the second coating surface, and a second recording layer laminated on the reflective layer. The protective layer, made of metal or semiconductor material, is formed on the second recording layer. The bonding layer is formed between the first access layer and the protective layer for bonding the first access layer and the second access layer such that the second recording layer faces the first access layer.
