For those of us who have been recording to CD-R, there's disturbing news that many brands of blank discs may last less than 20 months. See http://www.cdfreaks.com/news/7751 .
The original article is in Dutch, and when I sent to the site, it didn't have the brand ratings. Is there a Dutch speaker on the board who can has a copy of the magazine or can find a link to the brand ratings?
The comments say that recording at a slow speed (2X) seems to help, and that there's a lot of variation among CD-R brands.
Mark -- any experience on this? Anyone else?

Library of Congress had some data on longevity/error rates of CD-R.
If 20 months was an "average" kind of problem we'd have seen it surface a long time ago, though I'm sure that some inferior brands do deteriorate significantly faster than other brands (or perhaps there are bad lots out there).

Ken,
This is very disturbing indeed. I'll translate it ASAP. If I get stuck one of my cousins in Holland will help. Their English is better than my Dutch.
There was something a few years ago about fungus attacking CDs in Central America, if I recall correctly but I thought that was related to the humidity. CDs that I burned 2+ years ago still work fine. I would hate to lose my digital photos.

I read an article about this in a Dutch online newspaper a few days ago, but had no luck tracing it back. That article didn't contain a full list of brands tested and the results, but it did name a few.
Worst CD-Rs in the test were rock-bottom price CD-Rs sold by a discount drugstore chain - these are the CD-Rs featured on the two pictures that serve as an illustration to the article.
The common sense guidance given was to have two CD-Rs if the material's important - e.g. your digital wedding snaps - and to store the CDs sensibly/keep them scratch-free etc. Checking the CD-Rs and making extra spare copies on new disks every few years could also help, as would staying clear of white-label cheapo disks.

Thanks, Ken
My limited experience leans towards name vs. off brands.
I burned documents and pics onto almost a dozen IMITATION cdrs. After two (2) months, several of them would not open despite using three different computers.
I switched to SONY and haven't had a problem (after 9 months)........whether I use an internal or external burner/reader. The remaing IMITATION cdrs I transferred back to a file and reburned.
Granted, the name brand cdrs may not be manufactured by label, eg: SONY, MEMOREX, etc. but after my experience, I'll stay with what now works for me.
A name brand label may be more expensive but when bought in a 50 pack at say BEST BUY, on sale with a rebate, the end cost is most reasonable.
have a ![[happy]](http://test.woodwind.org/clarinet/BBoard/smileys/smiley12.gif) day

It appears that this problem exists with DVDs as well:

Yup. You buy junk - you get exactly what you paid for.

Audio CDs I bought 10-15 years ago still work fine. What are they recorded on?

Hi all,
It is best to stick to brand name media as this thread points out. However, having a good recorder helps as well. I use a Hewlet Packard writer. Why? It has a variable intensity write laser to compensate for imperfections in the media, fingerprints minor scratches etc. You pay more, but you get more. So...........What's your data worth? This is what it comes down to anyway.
Regards
Mark

beejay -
Commercial audio CDs are different from CD-Rs. On the commercial CDs, pits are physically stamped into metal. On CD-Rs, surface areas are burned by a laser.
Assuming that the polycarbonate sandwich is intact, commercial CDs have a long life. It's quite different with CD-Rs, which can deteriorate from high heat or bright light, as well as chemical changes in the recorded layer.
Best regards.
