Alright, I've read the topic, but still a bit unsure of myself
What CD-Rs can I safely buy and know that they won't die on me? I'm talking like the actual label on the package that you see in the store.
I currently use Maxell CD-R Pros. They seem to have a blue dye. Bad? Good? Please advise

I am not sure what to make of this. CMC Magnetics has the greatest number of failures in this poll, but thati might be like asking what brand of car do you own that broke down? Chances are that Fords and Chevys would leat the list because there are so many of them.
I have purchased CMC Magnetics CD-R's under the Imation, TDK, HP and GQ (Fry'S) brands. In fact, since thery don't tell you what is inside the package you have no way of knowing until you get home. It just seems like CMC Magnetics is the dominant brand. Try as I may, I never seem to wind up with anything else. So it must be the Ford or Chevy of CD-R's.
By the way, I have had no problems with them. I just ran a few quality tests using CD-Speed and there was not a C2 error on any of them regardless of which drive or recording software I used.

Yeah, it's a bit tricky. Sometimes Walgreens has 'em. Last time I found some at CompUSA, but only the 30 pack was made in Japan.
I guess your best bet is to buy Taiyo Yuden branded media online.

Anyone else ever buy some "That's Write" discs? I've had a few that - despite being well cared for - started skipping around in my Technics SL-P350 CD player (antique now, but still works after 12+ years), which rarely happens...
Anyway, all of the That's Write discs I have (bought in 2001-2002), started to discolour about a year ago. I have unbranded discs bought at the same sort of time which are still silver!
I haven't looked into testing any of these - I have a Plextor and it came with a copy of Plextools but it's honestly not something I've ever really needed (or even tried). Perhaps I should look into it...
As an aside, after having some bad experiences with TDK (having a HORRIBLE HP-8100 drive at the time didn't help - even after flashing with the hacked bios), I've been buying Sony CD-R's ever since, for important stuff. The current batch I have are in 50 disc spindles with the part no. 50CDG80SP5A. Indentifier and Nero say that these things are actually manufactured by Sony, and every disc I've burned has worked flawlessly. Perhaps these might be a good option for those that can't get hold of Taiyo Yunden discs (like myself... anywhere reputable in the UK selling these cheap?).

Really? Ouch.
I had two kinds of Maxell CD-R Pros both entirely different looking pakaging and disks (one had a blue top, the other one a gold one), but EAC identified both as TY. I'll have to watch out then.

A box of Lead Data (cyanine) discs sold as Memorex 700MB. Burned between 2 and 4 years ago, most of them are now becoming unplayable towards the end of the disc.
Also one Princo disc, branded Boeder 650MB, burned ~5 years ago, worked fine at first but now barely recognisable in most players (although still mostly readable in the drive it was burned in).
All the above burned in a Ricoh MP-7040A.
Do we have already a thread for bad DVD+/-R (RW) media, then this post should be moved, please ?
or maybe a new thread for dvd media ?
I have DVD writer NEC 1300 A with FW 1.08 (is it the latest?) and was really satisfied with DVD+R 4x speed from Ricoh 01/02 (or how they are labelled, could copy it from DVD-Identifier window,) so far.
Those Ricoh +R 4x speed were sold by several brands, ie. Philips sic !, the pack of Verbatim I bought, (German Aldi Medion), Platinum.
So, after my 5 packs trials and the surprise, that nearly every brand sold same Ricoh,
I bought a 25 spindle Platinum from local dealer.
All 25 discs were fine.
Then I bought those Platinum 25 from somebody at ebay.
These discs cause trouble at some files, which are burnt in the middle of the disc.
files burnt at begin, or end, are fine.
Most files check fine. But not some in a place lets say 1/3 -1/2 of possible space of the 4.7 GB.
These bad results were reproduceable, I made a direct comaprison file per file after nero burning.
The check against other media, ie. the same Ricoh label, but brand Medion from Aldi, a 5 pack, was successful, no bad files after burning.

I guess I've just been fortunate. Most of my discs are Memorex CD-Rs and I've yet to have one die minus bad scratching. Anything I think is valuable though gets burned onto at least 2 CDs. Can't be too careful.
I solved the riddle easily, why my first Platinum DVD+R 4xspeed 25 spindle was fine, but not my following Platinum 25 spindle.
The fine Platinums were RicohJPN0102,
the bad Platinum DVD+R 4x media: Ritek0102 !
Now i have Emtec (BASF) DVD+R 4x, a 25 spindle pack:
those are the fine RicohJPN0102 again,
and so not so surprisingly, the first written DVD checked ok.
Then I have some Verbatim DVD+R 4x in jewel case, the printable discs,
those are CMC , iirc as my check by dvdidentifier has shown.
Those checked fine, too, compare by bit content ok, but varying results by Nero tools cddvd speed read check.
iirc, Sony DVD+R 4x jewel case use CMC, too, and in past that medium checked ok for me, too.
edit addon:
I have read written by some german dvd experts, that the 25 pack spindle verbatim dvd+r 4x is normally CMC, and those aren't the best ?! The Verbatim dvd+r MCC , Mitsubishi Chemicals, should be the best.
It might be confusing me, and I will check my Sony dvd+r later, if those were CMC or MCC.
Nevertheless, the current verbatim dvd+r 4x 25 pack spindle CMC, gave good result so far with my nec 1300a writer.
(well, reading ok, bit for bit, but after burning various DVDs, the nero tool speed check resulted to different results, some discs perfect reading, some discs readable (according to bit-to-bit-comparison, but the dvd drive had to slow down for reading in Nero-cd-dvd-speed-tool).
btw, according to recommended media list by NEC for my NEC 1300A:
Ricoh & MCC media...

Check the new c't magazine coming out on Monday, they compare different quality testing methods: "Audiodev CATS DVD pro" hardware analyzer, CD-DVD Speed 3.01 on Nu Tech DW-082, KProbe 2.1 on Lite-On SOHW-832S and Plextools Pro 2.14 on PX-708A.
The conclusion about KProbe is that it's not consistent. Depending on the drive (different Lite-On models) you get completely different results that don't match the hardware analyzer's reference.
With CD-DVD speed, the results are depending more on the read speed that on the actual write quality, and again it's inconsistent among different drives.
Only Plextools give a rough estimation about quality, although the curves don't match with the Audiodev ones, but at least you could differentiate good and bad burns. It downplays the amount of errors, though.

Hi!
I have KProbe tested 15 cd-r's burned from 1995 until now, and I get some interesting results. The ones that are more than 8 years old works just fine (but the green color is darker now I think). I tested the one that got worst results (189 C2 errors) in another program CD Check, and there it was no problem reading the full cd.
Well, if anyone is courius, here is the results...

Can you post a scan of this review? Most tests at CD freaks, Speedlabs etc. show pretty consistent results of which media performs well & which doesn't even if PI/PO levels may vary slightly depending the drive/firmware. It maybe a good idea to scan a pressed DVD with your drive to use as a reference.
QUOTE(westgroveg @ Jun 29 2004, 03:07 AM)
Can you post a scan of this review?
Sure, although it was more of a sidenote. The real test is about DVD+R double-layer burning at 2.4x (which works quite well) and conventional DVD+-R single-layer burning at 8x and above (which is a desaster).
Anyway, here are the graphs. Topmost is the reference scan of the Audiodev hardware analyzer, which is widely used in the industry. The red line is the PI Sum 8 limit, so you see that the third burned DVD is of even worse quality than the second one (different scale).
As for KProbe, you see that it shows a good quality for the first DVD, which is ok. It shows the second DVD as having bad quality, but the graph doesn't match the hardware tester. For the third burn, it attests a great quality, even though it's totally beyond spec in reality. Only with the Plextools you get a rough idea of the quality here.

The only thing they have in common is they all have gold dye.

I've always got much better (though not prerfect) results with gold CDRs than silver.
The fact that my silver CDR got yellow proves that there was some SO2 attacking them, with light. If I'm not mistaken, silver turns yellow because of sulfur (can anyone confirm ?), and I've learned in school that silver can't turn yellow without light. If my problems, or a part of them, come from the metal, then keeping them in the dark would have improved their lifetime significantly.
yes, if they really use Gold particles/surface for the pressing, it will be chemically more stable than compared to a silver surface.
Silver (Ag) can be attacked/oxidized by Sulfur, S. The result would be Silversulfid, something black, maybe in low concentrations/thin films on surfaces 'yellow-brownish'.
To initiate a chemical reaction, you need often somehow a starter, to overcome a certain energy barrier, which you could overcome in a lot reactions by light, as sunlight contains UV wavelengths, which are quite powerful.
If I think of CD-R with organic compounds layers for the data, which are written/burned by our CD-writer lasers, then you know immediately, that any sunlight, maybe other light sources, too, are poison to CD-R.

There are four metals that are inert to polycarbonate and sufficiently reflective to be used as a reflective layer. These are gold, silver, copper, and aluminum. Aluminum is the most cost-efficient and most widely used for prerecorded pressed discs, but most CD-R discs use gold or silver because of their greater reflectivity. Since the translucent dye polymer layer reduces the amount of laser light that is reflected back from the disc, a highly reflective metal is desirable.

I was just asking, because silver sulfide (Ag2S) will turn black, not yellow - just try to eat an egg with a silver spoon. Silver Sulfite (AgSO3), the most probable silver/sulphur combination in presence of SO2 might be of yellow colour but cannot be created without the presence of water (air humidity, along with the fact that polycarbonate can take up water up to 1,5 mass percent might be sufficient) to create H2SO3 wich might then corrode silver ...

checking back cd-rs burnt 3 yrs back
ops.....found out "plasmon" rotten
black spots appear.
the data is till recoverable but i don't the disc will stand any longer
Plasmon is one of the worst brand i'd ever seen
Plasmon CD-R loads 2 times slower than brands like ritek, acer, mitsubishi, prodisc
but its still better than CMC
pressed CD - ~3 sec
ritek, acer, mitsubishi, prodisc - ~4 sec
Plasmon ~ 8 sec
CMC magnetics ~ 24 sec

I can simply explain why,
The first Sony Manufactured CD-R I used is "Sony 700MB/80min Supremas"

Very bad CD-R
my writer Artec WRR-52 refuses to write more than 74min on this media, and the speed is restircted to 40X and below
Sony CD-RW 4x-10x....650MB, are you sure they are sony?,
i think they are rebranded Mitsubishi disc, that's why they are good.
Almost all the 650MB CD-RW are Mitsubishi... I don't see any other manufacturer produce 650MB CDRW.
Verbatim's CD-R are marginal to good CD-R
"DataLifePlus (Azo)" are the best of Verbatim, they use Mitsubishi Chemical Corp. dye
"Datalife Pastel" are the best of verbatim too! they are Taiyo Yuden
DataLife/Valulife........Be careful! they are CMC!
I've seen many bad reports about CMC, but i found out that Imation CMC are quite good!

Black CDRs can be silver or gold. It's the plastic that is black. The silver ones that I got, from HiSpace, were manufactured by MPO. They had some C2 errors right after burning and quickly died. I don't remember who manufactred the Memorex ones, but for me they were worse.

Hi,
after I occasionally found this thread, I decided to join the party:
Recently I have reburned some 4+ year old CD-Rs due to read errors. I kept the originals though. So I fired up CDRidentifier and here are the results: (They fit quite nicely with the list at the beginning)
The worst of all CDs with lots of C2 and quite some CU errors was... CMC Magnetics (guessed that?

)
Next worst was LeadData, directly followed by AMS Technologies (never heard of them). Those AMS discs were sold under the Tevion/Lifetec brand in german supermarket chain ALDI.
Another disk I backed up (more out of fear that all my old CDs are crap now) was a Ritek but it was still perfectly readable (6,3avg/40max C1,no C2 or CU).
All discs (except one) were burnt with an old trusty PX-820i SCSI burner. They were stored in jewelcases (and therefore dark) under normal environmental conditions (not like Pio's

)
greets,

On a more positive note:
I just scanned a batch of Kodak Infoguard Gold (no speed rating) CD-R discs burned between 1993-1999.
All of them read back with very few C1 errors (on both LiteOn and Plextor drives) and no c2 errors at all.
So, using quality media, it is possible to get to the 10 year mark with data in tact, if the media is stored/handled properly.

Halcyon, do you think you could provide some scans?
I would attribute their long life due to the gold contained, not the media brand. If you check my list of old CD-R's scans I have a low quality brand (Princo) & it has lasted 7 years with no C2 errors.
What I would really like to see is 10+ years from non gold Kodak media, as I remember silver Kodak's where reported to be troublesome, that's why I bumped Kodak down on the quality rating list.
