What about double layer dvd recorders?

[PauloSilva]

Thats my question. should I wait for them or should I buy the normal 4,7GB DVD+-R/RW/RAM

 

[Boonesmi]

it will prbably be quite awhile till they are available and reasonably priced

i would suggest getting a dvd -/+ combo drive... the NU drive reviewed on the anandtech main page a few days ago looks like a nice drive and its only around $150

You won't find the dual layer DVD-recorders in stores before some time in 2004, and they will most likely cost a bit more. I'd go for a regular DVD+R, very inexpensive these days. But on the other hand the dual-layer burners might come in handy, if you are thinking of backing up your DVD-movies you most likely won't fit them on a regular DVD+-R.

Not only will these dual laser DVD burners be a while. They will likely be more than "a bit" more expensive. They will also more than likely be incompatable with everything else available right now. Get a nice inexpensive DVD-R or +R or +/-R. For about $150 you can't go wrong. And unless you feel the need to do a complete and total backup (ie all the special features, languages, soundtracks, etc) of your DVD movies, a +/-R disc is fine.

Incompatible with everything else available now? Says who? You?

Both Pioneer and Philips said that compatibility with existing DVD players was their MAIN priority when designing the dual-layer DVD-R and +R burners (respectively).

Current DVD burners are not capable of burning dual-layer disks because a more powerful laser is required to burn the second layer. But reading will still be the same, and the dual-layer burners will be able to burn on today's single-layer DVD-R and +R discs.

so is a dual layered disc the same as dual sided? (i didnt think so)

can your average, run-of-the mill DVD player play double layered?

what is the total capacity of a double layered DVD?

There are dual-layer DVDs which have 2 data layers per side.
And there are double-sided DVDs, which have data on both sides of the DVD. A double-sided DVD can have dual-layered or single-layered sides.

can your average, run-of-the mill DVD player play double layered?

If the reflectivity of a burnt dual-layer DVD+-R are close to a commercial dual-layered DVD, then the DVD player should play them just as well.

what is the total capacity of a double layered DVD?

~8.5GB

They WILL be compitable with your old standalone DVD-player.

Yeah, that one from Philips covers +R and this one from Pioneer covers DVD-R:

Click Me

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.

 

[Sid59]

dual layer discs (commerical) are already compatible.

I am only going to reply to the <attitude> section that someone seems to have. If you carefully read my post, I did not, in any way, say that they will certainly be incompatable. I said, and I quote myself here, "likely". I did not say "they will not be" compatable. I am willing to accept that I don't know everything, and my post did not claim that I did know or was certain about this fact. Thanks for the info, I am now more informed than I was at the time of my original posting. Too bad you seem to have an attitude, that is totally uncalled for.

So how long will it be before dual layered dual sided discs start hitting the scene? *THAT* would be one hella backup.

Also, will they produce dual layered RW's?

I was a bit wired and edgy from having to stay inside of the house with all windows and doors closed for 3 days straight (stupid fires), I guess I just vented some of that on you. I appologize.

I highly doubt dual-layered, double-sided recordable disks will ever be made. Not that it isn't possible, but it would just be too expensive. Even for standard DVD movies and DVD-ROMs there's VERY few that use those disks since they're so expensive. I think 2-disk DVD movies are probably a good example of this, packaging one disk would be cheaper than packaging two, so the only logical reason why they use 2 disks is because the cost to make a dual-layered, dual-sided disk is higher than making two dual-layered disks and the packaging to go with them.

As for your second question, IIRC one of the articles I read said that we shouldn't expect dual-layered +RW/DVD-RW disks. I don't remember the exact reasoning as to why, but I'm pretty sure one of the things mentioned was that RW disks make up a tiny portion of all recordable DVD disk sales so it isn't worth it. I wouldn't be surprised though if the cost of making dual-layer RW disks was simply too high.

Apology accepted. Hope things get better before they get worse with the fires too. I have a couple friends going to school in LA. They say it sux.
