Pioneer Develops DVD-R Dual-layer Recording Technology
October 07, 2003
Tokyo, Japan - Pioneer Corporation has developed DVD-R dual-layer recording technology, where data up to 8.5 GBytes can be recorded on one side.
The company also announced it will launch new DVD recorders with a built-in HDD to the world market. In Japan, Pioneer will introduce four new models in October and November, 2003.
The company reports that the new dual-layer DVD 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.
Pioneer's new technology will allow the users to record programs of up to about 4 hours in the SP mode, or programs of up to about 12 hours in the EP mode with DVD recorders.
The company will make a proposal of this technology as a new disc format to the DVD Forum after further improvement in performance, it stated.
Pioneer plans to introduce its new DVD recorders with HDD, including the DVR-510H-S in early October, and the DVR-515H-S in late-October, and the DVR-710H-S and DVR-610H-S in mid-November; no suggested retail prices were announced.
Pioneer's new DVD recorders are capable of high-speed dubbing at the recording speed of up to 24X*1. They also have the ability to record programs onto the HDD or play back the programs stored on the HDD even while high-speed dubbing is in progress. Thus, the users will enjoy easier and quicker dubbing at any time during recording. Plus, to meet various needs from the customers, these new products incorporate many original features, like "Disc Backup," utilizing the high-speed dubbing technology.
The DVD recorders conform to the DVD-R and DVD-RW formats.
