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.

In the rapidly growing DVD recorder market, there has been a strong need from users for longer hours, yet high picture quality DVD disc recording. 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 intends to make a proposal of this technology as a new disc format to the DVD Forum after further improvement in performance.

This is too cool. Pretty soon programs like DVDShrink will no longer be necessary. :)

SWEET! 4.7GBs just aint enough sometimes. :)

Man, I was just thinking about this earlier today, and was ABOUT to post a thread asking, "Why can't they make dual layered DVD-R's?". GREAT news!!

Posted by: Bryanmc

This is good news.

I've had quite the frustrating time trying to squeeze a client's 2+ hour show onto a DVD. It will be nice when that's no longer a concern.

Sign me up baby, I'll take the first one off the line. :D

I was looking for this! Thanks Dan! I was watching TechLive on Friday and saw something about this on the news ticker but it was never mentioned again. I searched but didn't find anything. Great news...bummer that my early investments will be replaced though. :)

This is what I have been waiting for before getting DVD-R. I have 150ish DVDs and I want a easy way to copy them.

GJ Pioneer.

Bry, you could always make the client DVD over 4.3GB and then let DVDShrink or Instant Copy squeeze that down to a single layer size.

I've got plenty of tools to do different levels of compression and encoding. I could shrink it down to 5 MB if I wanted. :D

The point is quality. Most of the stuff I work with has to be suitable for broadcast. (My discs are never used for broadcasting, but the material they come from is and I have to have the quality match.)

So it's not just a matter of fitting it on, but fitting it on and it looking good.

Just out of curiosity, why? I have over 200 DVDs and not a single one has ever gone bad. Just seems like a big expense if only copying for 'archival' purposes.

"Philips will demonstrate its new dual-layer DVD recordable technology at the DVD+RW Alliance booth at the CEATEC* JAPAN 2003 exhibition in Makuhari (Chiba, Japan) from October 7 to 11. Developed by Philips Research in cooperation with MKM (Mitsubishi Kagaku Media)/Verbatim, the technology virtually doubles data storage capacity on DVD recordable discs from 4.7 Gbyte to 8.5 Gbyte while remaining compatible with existing DVD Video players and DVD-ROM drives. "

So which would you choose, dual layer + or -, Raj? :)

Hopefully, Sony will come out with one that does both.

If someone if gonna borrow a DVD, I would rather let them take a burned one, cause a few of my DVDs never found a way home.

Also, I may start using netflix if I had this Pioneer hardware. ;)

This press release seems like a rushed attempt to dampen the Philips announcement about the dual-layer +R disc they will be demonstrating shortly...

Cool! I prefer the +R/W format, as it works better with my current equipment.

I wonder if any of the current drives can be flash upgraded to work with this media? Or if it will require new hardware?

Just as early standalone DVD players initially had problems with DVD+Rs and DVD-Rs and later with DVD+R/Ws and DVD-R/Ws, I wonder if current players will have problems with these new dual-layer disks and if we'll all have to buy new players to be able to play them.

Posted by: Dan203

My RCA DVD player, purchased in 1997, can play both DVD+R and DVD+RW. I could NOT get it to play a DVD-RW and I have not tried a DVD-R yet. So it's not guaranteed that just because your player is old, it will not be able to play these new disks.

Thats what I was wondering...It may just be wishful thinking, but from this statement:

Both Philips and MKM regard the introduction of dual-layer DVD+R technology as the next important milestone in the drive to continually improve and expand the optical data storage options available to consumers. Users will benefit from the additional storage capacity of the DVD+R disc as it will enable them to record 4 hours of DVD-quality video or 16 hours of VHS-quality video, without the need to turn over the disc. PC users will be able to archive up to 8.5 Gbytes of computer files on a single disc, which almost doubles the storage capacity compared with the 4.7Gbytes for the single-layer DVD+R discs currently available.

It almost makes it sound like the breakthrough is in the media. All DVD-burners can obviously change angles of the lens since they have to be able to read dual layer discs, but I wonder what else is involved.

crap...nevermind:

All future DVD+R9 drives and recorders will also record on DVD+RW and standard single-layer DVD+R media. Single-layer DVD+R media will remain to be available, as it suits a lot of recording purposes, and they are likely to be cheaper to manufacture. Current DVD+R/+RW drives and recorders cannot record onto DVD+R9 media, however, since DVD+R9 is fully compatible with the DVD-ROM specifications, they will be able to read those discs recorded on other equipment.

Still hope with -R:

According to Pioneer, a dual-layer DVD-R recorder would need to be developed to record on DVD-R dual layer discs, but as they are still working on this technology, this may still change. It looks like the DVD '-' standard is here to stay when it comes to dual layer DVD recordable technology.

Darn. :(

Although considering the price of DVD recorders these days, it may not be all that bad to have to replace mine when these become available. :)

Cool! So when do we get a dual-layered DVD-R TiVo?
