How long till burned dvd deteriorates

#1

Was just wondering if anyone knows how long it will take for a dvd back-up to deteriorate. 3 yrs, 5yrs, 6yrs. Just wanted to know because my back-ups from 3 yrs ago still work. I am new to posting but have been reading posts since 2005 and have not been able to find a post like this.

if your using stuff like Verbatim (16x cert DVD+R… burned @ 8x) or Taiyo Yuden (8x Cert -/+R’s burn @ 8x) … i think it’s a pretty safe bet that they will last 10+ years (assuming you dont happen to get a bad batch etc) … if not much more from peoples scans i have seen from a few years back that show very little to no degradation.

thanks NBR I use TY blanks now but in the beginning I used the cheapest ones on sale. I will keep an eye on those. I always burn at 4x even if they say I can burn faster. Thanks again

if u got a 8x cert disc or especially 16x cert… u ‘might’ be actually getting worse quality burns when burning @ 4x on a 16x cert disc.

if you got a good scanning drive like lite-on etc… you can run a disc quality check with kprobe and see how good the burns are etc. and then burn @ 8x and compare.

also, (atleast in USA) i think verbatim is overall better than ty just cause you can usually get Verbatim noticeably cheaper vs TY and there quality is about the same give or take a hair.

in general … if u got 8x cert discs or higher, 8x is usually the sweet spot for burning in general.

Seriously now, there is not answer to that question. Different makes of discs degrade at different rates; the way they have been burnt impacts the degradation rate; heat, light, humidity impact the degradation rate; storing habits and handling impact the degradation rates… there are simply too many factors!

I survey my own DVDR collection since 2005. Some of my discs seem to not deteriorate at all, I mean that after three years the scans show no significant variation, if any. Some others have died after only a couple of months (thankfully this was limited to a couple of MIDs). Many discs are somewhere between these extremes.

That is correct. There are many burners that won’t pull off correct @4X burns with 16X rated media. @8X is faaaaar safer than @4X, and most of the time gets the best out of 16X rated media whatever the burner. Sometimes the sweet spot is @6X or @12X, but I consider @8X the best bet in almost all situations. If you don’t scan your burns, stick with @8X. :iagree:
