Forward Versatile Disc

Forward Versatile Disc (FVD) is an offshoot of DVD developed in Taiwan[1] jointly by the Advanced Optical Storage Research Alliance (AOSRA) and the Industrial Technology Research Institute (ITRI) as a less expensive alternative for high-definition content.

[2][3] The disc is similar in structure to a DVD, in that pit length is the same and a red laser is used to read it, but the track width has been reduced slightly to allow the disc to have 5.4 GB of storage per layer as opposed to 4.7 GB for a standard DVD.

The specification allows up to three layers for total of 15 GB in storage.

FVD uses AACS copy protection which is one of the schemes used in both HD DVD and Blu-ray Discs.

FVD-2: The second generation will use the more efficient 8/15 coding for increasing the ECC capability (to avoid DVD patents).
