Abstract

A new optical disc format with 650nm laser is introduced, which receives capacity of 5.4 to 6 GB for single layer and 9.8 to 11GB for double layers. The technologies developed in this new optical disc, including new data modulation code, error correction code, content protection and technologies related to triple layers disc, are also presented. For blue laser recording technologies, two kind of optical pickup head with 405nm laser were integrated. The resulting spots are observed. For terabyte storage, some advance technologies are developing. The spot overcoming diffraction limit and gap controlling are two major subjects for near field recording. Volumetric storage by multi-layer stacking could approach several hundreds gigabytes. The fluorescent material is adopted in multi-layer disc for reducing signal interference between layers.
