[QUOTE=Aramchek;2171909]Depends on which Mitsubishi Verbatim DVDs (with some exceptions) are made for Mitsubishi Kagaku Media / Mitsubishi Chemical corporation by various outsourcers using their equipment and materials (plus some made by MKM/MCC themselves).
The problem is there are several Mitsubishis (even though they have their roots in a single company) and there is also media branded Mitsubishi Electric which is NOT made using the same equipment and technology as Verbs. It should say on the packaging which of these two Mitsubishis the discs are from.
And “Mistubishi” disks are probably only made when the weather is bad :-)[/QUOTE]
I see. There’re even outsourcers from Verbatim? Lol. Btw, didn’t heard of Mitsubishi Electric before. Is it genuine too? Besides, wat do u mean by Mitsubishi disks are made when the weather is bad?
I hereby enclose an attachment of my DVD’s label too. It should be the correct one, right?
[QUOTE=evo69;2172086]To make things clear, the maximum official rating for any DVD media is 16x, however newer drives now support writing these discs at up to 22x. The discs that are able to reach 22x are severely limited though, so YMMV. This forum recommends burning discs at the maximum rated speed (and the DVD standard) 16x - 18x, 20x, and 22x are just there for marketing purposes and does not give any significant burning time advantages (except maybe giving you more bad burns).
Yes, they are more prone to screwing discs when burning at higher speeds than what the disc is rated for. Burning at 16x is the fastest recommended speed as these discs are originally rated at 16x, although results of the burn may even be better at 8x or 12x (6x for 8x media). Burning over the rated speed may only be successful if high-quality media is used, and the results largely depend on the quality of the burner itself and not only the media. Burning at the maximum rated speed and overspeeding high-quality discs have not been proven to severely affect their lifespan, however since there are more chances to screw up and waste expensive discs, burning at less the maximum speed is the CD Freak’s normal course of action (burn quality over speed).
100 years = untrue. At the most perfect archival environment (climate controlled etc.) my guess would be 20-40 years, but since DVD technology is younger than that, there’s no real-world proof that they last that long except for accelerated aging tests. At the normal joe’s shelf/basement (not the sloppy joe :p) I’d give it 5 years, and at the CD Freak’s storage probably about 10-15 years - and that is if it will never be used until it is needed.
As Aramchek said, only spindles marked as Mitsubishi Kagaku Media/Mitsubishi Chemicals Corporation and not Mitsubishi Electric are the only “real deals”. I use Mitsubishi-branded media (and I have a ton - love them because they’re cheaper in my country) aside from Verbatim DVDs, and from tests they are entirely similar to Verbatim except for the branding and designs.[/QUOTE]
YMMV? Joe’s shelf/basement? & the sloppy joe? Well, I dun really get wat these mean. Mind to explain? =p
So, is it possible that burning at 16X is even better than 8X or 12X, since some said that the drives are optimized for high speed? So, generally, burning at the disk limit is still fine? I think burning at the burner’s limit is not wise, right?
Btw, I store my discs in a room where I’d turn on & off the air-con. The change of temperature probably is from 30 degree celcius to 24 degree celcius, & 16 degree celcius in rare case. While in hot days, the temperature might rise to 34 degree max. Do u think it’s still fine for storing the discs?
In my country, both having around the same price. Do u think that Mitsubishi is more promising in quality, since it’s made by the manufacturer itself while Verbatim would have some exception to have other manufacturer?
It has been shown that original jitter levels on CD-R are (negatively) linked to disc stability over time. Granted, DVDR are no the same thing as CD-R, but given the fact that both use organic dye, it’s sensible to expect a similar behaviour from DVDR. And guess what impacts jitter levels most consistently? Guessed right, burning speed. - the higher the burning speed, the higher the jitter levels, especially near the outer edge in the last ~500 MB.[/QUOTE]
I experienced higher PIE/PIF error in my last part of my burn too. I was wondering why is it so… It’s bcoz of jitter? Btw, wat’s jitter actually, in a brief & accurate explanation?
I’ve burnt lots of MCC 02G20 (Verbatim 8X -R). It’s a very stable MID, both in my experience and from accelerated aging tests. Despite this, all of the MCC02RG20 blanks I’ve burnt in a bad burner (JVC DR-M10) have shown a very fast, even catastrophic, degradation rate in my survey (scans performed 2X a year). So burning quality definitly impacts disc stability.
Besides, how was ur initial quality scan of the DVD burned from the bad burner?
Nobody can predict how long the disc will last. Anyone who claims to be able to predict that with any certainty, is either lying (a.k.a. marketing) or doesn’t know what they’re talking about (a.k.a. marketing).
Marketing = lie or ignorance? Lol!
