The new optical disk format, called forward versatile disk (FVD), has been developed in Taiwan. Some physical technologies, such as recording on narrower groove, new modulation code, and new error correction code (ECC) have been verified. The feasibility for producing triple-layer FVD has been proven. In addition to the read-only memory (ROM) type, the format for the recordable/rewritable FVD type is also developed. These technologies of FVD with red laser will be applied to the next generation. Blue high-definition (HD) FVD will adopt most red HD FVD technologies. For higher recording capacity FVD, technologies such as super-RENS and multilevel recording for next-generation FVD are continuing to develop.
