anyone have an estimate for dual layer dvd burners?

[madman300]

Just wondering anyone have any clue on an estimated date of arrival to the market?

You cannot burn a dual layered DVD's, due to the way they are made.

They are pressed with machines that cost lots and lots of money, sure you can buy one of these machines, but it would not be worth it, as they are meant for factorys that press in large quantity's.

They will come out with them soon so be patient,since I dont see them going any faster than 12X burning they will have to speed thing up some other way & dual layer burning will do it.

Not if Philips and MKM have anything to say about it! Granted, these aren't made the same way as a pressed dual layer dvd, but then again, the software and music you buy in a store aren't burned either.

EDIT: No! Beaten with my own link!

The more optimistic manufacturers reckoned April apparently....personally i think it could be anything up to August before they really show. The major dissapointment for me is they are only going to be 2.4x speed in the dvd+ camp...the speed of pioneers dual layer dvd-r is an unknown but that probably means 2x there. I was really hoping for the possability of 4x performance since 8x single layer is begining to take off and we should have 12x or even 16x drives in a year or so. Takes a long time to write and verify a dual layer disc at ~ 2x ;p ( couple hours).

EDIT: yup, make that 16x

EDIT AGAIN: Above article reckons H2 for dual layers...lol, its like i had a vision


I found it interesting with the information released recently that both layers MUST be recorded for the disc to work...so if you go over the single layer boundary, your gonna have to write the same amount of dat on the 2nd layer, whether its real data or just padding. They talked of splitting the data equally between layers on the dvd+r dual layer discs, so you basically dont write the outside of the disc at all on either layer if the full 8.5GB capacity isnt required, meaning the time required is simply that to write the desired data only. Thats great for PCs....but it wont work for standalone consumer dvd recorders, as an unkown amount of data would be getting reqcorded..so they spoke of finalisation sessions involving burning the necessary padding info on the second layer after the recording was finsihed if the disc wasnt entirely full. so thatd mean recording every dual layer disc in a standalone recorder in its entirety (1hr, since they dont verify AFAIK).. ouch.

Verbatim Announces DVD+R DL Media at CES

Verbatim's target launch date for the media is spring 2004, and they expect that date to coincide with the availability of new recorders capable of writing dual-layer discs in DVD+R DL format. According to Verbatim, the discs will require no adjustment to existing DVD players or DVD-ROM drives to read DVD-Video content written to the DL media.

DVD+RW Alliance showcases its single-sided dual-layer DVD+RW/+R media and 16x DVD+R

CES 2004 exhibits supporting recordable single-sided dual-layer DVD+R were initially introduced as far back as in last October at CEATEC in Tokyo. The method of recording and playing dual-layer DVD+R is simple and known since dual-layer DVD-ROM: the second layer is accessed by optical refocus. Still the speed in case of this dual layer is only up to 1x. But there's full compatibility with DVD Video in place. The total capacity of such a disc is therefore increased from 4.7GB to 8.5GB. The drives supporting single-sided dual-layer DVD+R are expected in the market already this Spring.
