October 3, 2003, Tokyo, Japan - Pioneer Corporation has announced today that the company developed the DVD-R dual-layer recording technology. It means that the technological foundation has almost been established to commercialize DVD-R discs, where data up to 8.5GBytes can be recorded on one side.
The new dual-layer recording technology, adopting the dye-recording-film layer method, has realized a 9.34% jitter with a 17.3% reflection rate on the first layer (L0) of a disc, and an 8.08% jitter with a 19.5% reflection rate for the second layer (L1). This shows almost the same performance as that for dual-layer DVD-ROM discs. It means that DVD-R discs supporting this technology can be played back on most existing DVD players, and DVD recorders supporting this technology will be developed easily.
