DVD "Dual Layer"

Folks - I assume my model (iSight - last version) came with a "dual layer" DVD RW. Does this mean I can burn 9G DVDs? What is "dual layer"? Thanks.

Yes, you can burn dual-layer DVDs on your iSight iMac. The capacity is about 8.5GB per disk.
A DVD contains a layer of an ink substrate that is hit (burned) by a laser. The laser creates small holes in this ink. A dual-layer DVD obviously contains two layers of this chemical and by adapting the laser intensity both layers can be written.
It is like an old vinyl record, only where both sides are on the same side of the disk.

  • DVD Dual Layer Not Working?

    Hi all!
    This is my first time to these forums and I have some trouble with a used Toshiba x205-SLI1 I just bought. the HD Dual Layer burning does not function and the driver appears to be updated properly. It is a TS L802a model, with drivers dated as of 6/21/2006 version # 6.0.6002.18005.
    When I insert the Memorex HD +R Media Nero 9 runs up and begins the process but only goes to about 1% then stops. It ejects the DVD which apears to have nothing written to it by looks since I can put the DVD back in and there are no written areas all i can see with data.
    Plus the speed of the drive only reaches 2.4 when the max is 8X.
    Is there a newer driver somewhere? I need to get this working if possible and without spending tons of money on different media types to "test" the Burner.
    Does this burner have some inate problems as i have read on other forums in burning dual layer dvd's?
    oh, and it does work with the normal 4.7GB DVD's just fine i have done several of these to back up data on the system.
    The system is running as the following drive configuration:
    2 @ 200GB Raid 0. Vista ultimate 64 upgraded from Home Premium by the original owner.
    The Laptop works in everything else and is in pristine condition all over.
    Let me know if more info is needed to make a determination for help please.
    Thanks in advance!

    It sounds like a hardware problem to me.  Your best bet considering it is new is to take it back to the place of purchase and exchange it for a working model (if it's within the exchange period) or contact Toshiba Support and have it repaired under warranty.  Se the Warranty Link at the top of this page for details.
    If you don't post your COMPLETE model number it's very difficult to assist you. Please try to post in complete sentences with punctuation, capitals, and correct spelling. Toshiba does NOT provide any direct support in these forums. All support is User to User in their spare time.

  • DR8-A firware upgrade to dvd dual-layer?

    I am very happy with my DR8-A burner, but i am wondering if MSI has any plans to upgrade the firmware to the future Dual-layer dvd formats.  I have read that Bueq is offer this for their new drives.

    if it can upgrade to 8x8 - good or bad news  

  • G4 DVD Dual Layer question

    I have a 14" G4 1.07GHz iBook with a Non DVD Burning CD/CDR/CDRW/DVD drive. My question is, will it READ a dual layer DVD? Thanks!

    Hhmmm...let me know if it works for you. I have (I think) the exact same setup, and my drive spits out dual discs. We bought Bruce Springsteen's The Seeger Sessions, which is a dual disc, and I had to resort to alternate methods to import the songs into my iTunes library. I Googled after having the problem and found others who had the same problem.

  • DVD dual layer write speed?

    Anybody know what the maximum write speed of the Superdrive is, for dual-layer DVDs?
    I have a late 2011 MacBook Pro 15" and I want to buy some blank DL DVDs.  I'm looking at Verabtim DVD+R DL blank media.  They offer both 2.4X and 8X speeds.  I've read that the 8X disks - which are more expensive, roughly 15 for the price of 20 of the slower disks - can be a problem for older drives that don't support that speed.
    I already know that my Superdrive will write at 8X or more for a single-layer disk.

    "Be sure to take full advantage of:
    About this Mac > ( More Info ) > Disk Burning ..."
    Yup, this showed me that my 8X (single layer) disk could in fact be burned at 8X, but without any DL disks for testing, ATM doesn't tell you anything about burning speeds.
    Thanks for the confirmation that I do NOT want to buy the 8X disks.  I've gone ahead and ordered the 2.4X Verbatim disks.  I also saw some labeled as 2.4-6X, and I suppose those would work with my 4X drive.

  • DVD dual layer blank media problem

    Hi,
    I used HP branded media without any problems in the past. Now I got a roll of Ritek dual layer DVDs and most unfortunately the drive ejects them as if they were incompatible.
    Does anybody know if Apple keeps a page with compatible media? Or is there any indication which brands would work and which don't? The dual layer media is still quite expensive and I don't know if I can convince the retailer to take back opened disks...
    Best
    Jurgen

    If they're DVD-R DL discs then there's the problem. They should be DVD+R DL.

  • DVD Dual Layer, +/- which is better?

    I've been trying to burn a dual layer DVD-R DL from iDVD6 but it won't let me, it will however let me burn a DVD+R DL even though my burner can burn both. What are the benefits however of burning one from the other as iDVD seems to mainly support DVD+R DL whereas it is always recommended to use DVD-R when burning single layer?

    Thanks guys.
    The problem is I purchased a Dual layer external burner by LaCie and after some digging it appears that although it is capable of burning both +/-R DL, my system profiler only states +R DL, however I can burn -R DL through both system utilities and Toast so this leads me to think that there is a lack of support for -R DL on iDVD6 (whether this is due to the incorrect system profiler provided by LaCie?)
    I've had a few tests and iDVD6 just spits the DVD-R DL back not recognising it as a dual layer disc. I've been on to LaCie and Apple about this but they're both passing off blame to each other.
    Am I right in assuming that DVD+R DL can play ok in most DVD players? I obviously want to create a stable disc and burning DVD-R DL through system utilities has given me many problems on various players.

  • DVD Dual-Layer Drives Recommendations

    I am looking to get a Dual Layer DVD drive.
    Does anybody have a good recommendation? Internal? or External?
    Oh by the way, I am still using DVD SP2, do I need to upgrade?
    Thanks
    Paul

    I am under the impression that even Toast 7 will not read the dual layer break point set by DVDSP in either a VIDEO_TS or a disc image. Believe me, I would love to find out that I'm wrong on this. This ability alone would be worth the price of the upgrade for me (I'm still using Toast 6).
    Someone asked a question specifically about this either late last week or early this week in this forum, and I believe it went unanswered.
    This recent post on the CreativeCow was the closest answer I could find: http://forums.creativecow.net/cgi-bin/newreadpost.cgi?univpostid=859311&forumid=155&postid=859517&pview=t
    I have not used Discribe, so I can't speak for its abilities. Its website isn't very helpful in this regard.
    Hopefully someone who has firsthand experience trying this will post a reply.

  • Help! DVD dual layer settings

    I am trying to burn a 1hr and 47 minutes movie onto an 8.5 gb dual layer dvd. When I try to format this message comes up:
    Formatting was not successful. The image exceeds the maximum allowed size for a dual-layer configuration.
    I cannot get a successful burn. And also, when I make a break point it's still the same thing:
    layer 0 exceeds layer 1?
    What do I need to do to have a successful burn with a dual layer DVD? Settings?

    The first layer (layer 0) must must be bigger than the second (layer 1), in other words, your layer break must be past the "halfway point" in your media, but before the "halfway point" of the total capacity of the disc.
    You would only see this message if you had manually placed a layer break marker. You have two options:
    1. move the layer break marker to a position that meets this condition, probably earlier in the main video track
    2. rearrange the contents of the disc in the VTS pane of the outline tab. There'll be a little button at the top right of the outline tab that will toggle between the two views, or you can drag the veritcal divider in this window to see the two columns in the outline tab. The VTS view shows you the order in which the media is physically arranged on the disc. You can rearrange these by dragging.
    Hope this helps

  • DVDs - dual layer? +?

    I have this new goddess of a 24" iMac here, and am just burning my first DVD. I've always used DVD-R. Can someone tell me if this iMac will burn dual-layer DVDs? The System Profiler says it will burn "-R, -RW" discs. Does that mean I can't use a "+R" or "+RW" disc? What are these discs, anyway?
    Thanks. This machine may be smarter than I am, but I'm not ready to give up.

    I'm not sure if I can give you all the answers you want, but iMacs will burn +R and +RW DVDs as well as -R and -RW DVDs. The specs say it will also burn dual-layer +R DVDs, although I haven't tried that myself yet.
    I hope that helps.

  • Leopard DVD Dual Layer?

    I read somewhere that the Leopard DVD is a Dual Layer disc. Can anyone confirm this?
    The reason I ask is because Apple just says "DVD drive" which I take to mean "a drive that reads DVD-ROM disks". My G5 iMac has a SuperDrive but my 1.25 GHz 15" G4 Al-PowerBook just has a Combo-drive. I don't think either of these can read Dual Layer disks, or am I mistaken?

    Steve Macko wrote:
    Bad news first... It is certainly a dual layer DVD. Good news... Most commercial DVDs are, and they can be read by any DVD drive! The single layer versus dual layer only comes into play when creating and burning discs, not reading them.
    Just about all DVD movies are dual layer, and have been since the beginning.
    Steve
    Thanks, Steve.
    I know that DVD hierarchy were originally single-side, single-layer; dual-side, single-layer; single-side, dual-layer; and last dual-side, dual-layer. I didn't know that all DVD drives could read any of these. Of course, I'm ignoring the two HD flavors.

    My supplier told me that

    others work perfectly".
    So I don't know which DVD I can take..
    Has anyone used successfully some kind? And which?
    Tnx

    There is a web site that rates DVD media brands. Verbatim DL is what I use and never had trouble.

    I think BB has hit the nail on the head. Verbatim as a brand has a reputation for quality and wide compatibility surpassed only by Taiyo Yuden.

  • Recordable space on DVD-R vs. Dual-Layer DVD+R

    I have the PB 17" 1.67GHz Nov 2005 model with the DVD dual-layer burning drive.
    I bought a 15 pack Memorex DVD+R DL recordable 2.4x, 8.5GB, 240min video to experiment some with this media.
    On many of my DVD-R Single-Layer discs I can record data up to around 4.3 GB at a pinch. I notice that the DVD+R Dual-Layer disc will only record data up to around just under 8GB using Toast Titanium v7.0.2 in each case. Is this to be expected ? I was hoping for much closer to 8.3 GB. If the 8GB is all I can expect what is the 0.5 GB being held back for and what is this user-unusable spaced used for ?
    Thanks... Barry
