mbyllhmswslq Posted January 14, 2008 Share Posted January 14, 2008 So I'm guessing this has been answered somewhere before, but I can't find it. Whenever I burn a disc with ImgBurn (2.3.2 and before), I choose MAX wrtie speed. However, ImgBurn starts out slow (say, 2x for DVDs and 4x for CDs) and then eventually speeds up. The problem is that it takes a lot of time between speed increases. I have an 8x DVD burner, and ImgBurn usually never reaches 8x. It spends 20 minutes or more buring at like 4x. With CDs, it never reach 24x, only 20x if the CD is full of data. Does anyone know why this is or has anyone else had the problem? It like sa staggered speed-up, but it takes way too long. I've had this issue on multiple drives and systems, too. Thanks! Link to comment Share on other sites More sharing options...
dontasciime Posted January 14, 2008 Share Posted January 14, 2008 Depends on which DVD writers your using and if smartburn or the equivalent is implemented on your writer and your using sub standard disc's. Lots of writers stagger the write speed as part of their strategy to write the data to the given media the best it can. Link to comment Share on other sites More sharing options...
spinningwheel Posted January 15, 2008 Share Posted January 15, 2008 In addition to what Donta said above...it's a matter of physics, as the writing head moves outward on the disc, more info is placed on a track, therefore a faster write is achieved. Remember the physics question about what the fastest moving part of a tire is...it's not the rim but the tread...because of it's physical difference to the innermost part Link to comment Share on other sites More sharing options...
blutach Posted January 15, 2008 Share Posted January 15, 2008 Visualising ..... If something is spinning around at a constant speed, (lots) more bits can be placed on the outer than the inner in the same amount of time. IE. Write (and read) rate gets higher as you move to the outside of the disc. Regards Link to comment Share on other sites More sharing options...
mbyllhmswslq Posted January 18, 2008 Author Share Posted January 18, 2008 True. I brought it up, though, because programs I've used in the past don't have an issue with burn speed. If I select 24x for a CD, I get 24x from the start. Same with DVDs. It's just annoying because if I select MAX speed, I expect the burner to kick up to MAX speed from the start. I dunno. Maybe I'm just picky Link to comment Share on other sites More sharing options...
LIGHTNING UK! Posted January 19, 2008 Share Posted January 19, 2008 You might see 24x from the start but it's not a true reflection of the speed they're working at. I could lie and make it say MAX all the time if you like?! (just kidding, I'd never do that really) Link to comment Share on other sites More sharing options...
dontasciime Posted January 19, 2008 Share Posted January 19, 2008 I presume you mean Nero Nero lies it says writing at 24 etc but it's not add a couple of registry entries to Nero 6 / 7 and you see the true write speed. Nero 8 maybe [ Nero 7] has a tick box to do this now truespeed.rar Link to comment Share on other sites More sharing options...
mbyllhmswslq Posted January 23, 2008 Author Share Posted January 23, 2008 Alright, makes sense. So how about this one: Why does ImgBurn slow down before it goes up to the next speed level? Link to comment Share on other sites More sharing options...
cornholio7 Posted January 23, 2008 Share Posted January 23, 2008 imgburn doesn't , your drive does, all drives behave differently, my pioneer stops when it shifts from 6x to 8x , benqs just speed up Link to comment Share on other sites More sharing options...
