Abstract:
A dual-path optical recording medium and an apparatus for accessing such are disclosed. The dual-path optical recording medium includes a substrate, an intermediate recording layer, a holographic recording layer and a dichronic mirror layer. The intermediate recording layer is a rewritable data storage layer with a relatively low storage capacity. The holographic recording layer is a write-once data storage layer with a relatively high storage capacity. The dichronic mirror layer is located between the holographic recording layer and the intermediate recording layer. The apparatus for accessing the dual-path optical recording medium includes a first light module capable of generating a first laser light, and a second light module capable of generating a second laser light.
