Zusammenfassung: | The utility model relates to a mirror frame type optical disc which comprises a basal body which comprises information tunnels, and a metallic reflective layer. The utility model is characterized in that a protective glue layer is coated on the metallic reflective layer by screwing, a printing layer is printed on the protective glue layer, and a white sheet is adhered to the printing layer through an adhesive layer. On one hand, because the printing layer is arranged above the basal body and under the white sheet, the printing layer is effectively protected and can not be damaged, and the visual effect that patterns are put into a glass mirror frame is generated to make the patterns more bright. On the other hand, the printing layer is printed on the protective glue layer, and the protective glue obstructs the direct contact of the printing layer and the metallic reflective layer and prevents the reflective layer from oxidating by the printing layer. |
