CDR lifespan ? [message #101039]

I've got CDRs that are going bad after just a couple of years. They have
no scratches and are in perfect condition. Apparantly the dyes are unstable
and fail from what I'm reading.

Has anyone researched this to know what the best brands are and what can
be expected or are they all bad this way?

Thanks,
John

I haven't had any problems with mine - differernt brands, both cheap and
expensive. All are at least 4 years old, and some near 10(Verbatim brand).
I hear they are subject to ultra-violet light and non water-based ink bleed
thru.

I use exclusively (unless a client is absolutely insistant) verbatim. They
offer up to a 100 yr shelf life if stored properly.

I know these problems too from earlier on different CD's and DVD's. I
know, a periode, there were problems with paper glued on some discs,
that started a chemical process that was destroying. But I have also
observed problems when changing player. Had a 6 years old project
backuped on blank CD's with glued paper, that I wanted new backups on
DVD's. 6 of 8 discs were destroyed. Luckily, I know the project never
wouldl be remixed.
I have really good results with Verbatim, Premium and MDA here in
Europe.

Good luck

I Have discs stored in my garage that were burnt sometimes over 8 years ago...
they still work and get read fine. They are different brands. I also have
had issues of reading discs... but it was usually the disc reader that was
the problem. They do wear out after some time. Of course they are pretty
cheap these days and easy to replace. Unless it is a notebook. That isn't
so easy or cheap. I would suggest to try to same discs in a different reader
before pointing the finger at the discs. Of course a big culprit to this
dillema had to do with the manufactures and the fight for plus or minus (+/-).
I have a pile of mp3 minus (-) dvd's that were burnt long ago... but some
disc readers do not like them. So I make it a habit to purchase nothing
but the plus (+) discs. They seem to be more uniform or universal -- imho...

This particular disk that went bad has a full cd size adhesive label on it.
Maybe the glue hosed it.

Can I write on the backs with a sharpie or will that mess them up (as I have
200 dvds with sharpie on them already).

(soft) Sharpie (oxymoron) should be fine.
We use Taiyo Yuden

I also use Taiyo Yuden. Don't know about shelf life but they play on everyone's
machines where some others do not. I do not use Sharpies. They can leach
thru and destroy data. I use felt tip pens designed for CD-R's. They're
not too hard to find.

The logic is that the sharpee, unless specifically for CD/DVD r and r/w
makes a chemical reaction over time that is not good for the substrate layer
and will degrade it.

All the above. Or online, if you want to be lazy. WalMart may even have
them.

You can use the -, but the recommended configs are - for video and + for
data. Either will do either format.. it's just a legacy thing.

First of all, DVDR+ is a newer format that, as one of the two
standards, can be used on "more things", as far as I remember.
Here's one of the internetsides with som explanations:

Mix magazine did a series on the dies and their properties .If I remember
right,pthalocyanine is what you want.
pthalocyanine has a characteristic blue tint.as opposed to cyanine ,which
has a green/yellow tint.
get the blue shit!

One other thing I might mention is that a friend had her DVDs going bad
after repeated cleanings with Windex and/or alcohol - no scratches, but they
no longer read.

If it's necessary I use a neutral cleaner or gentle soap. Anything that
leaves a residue would be bad. Warm soapy water, rinsed immediately and
dried in a center to edge motion with a lint-free cloth has yet to fail me.
