Re: [ARSCLIST] CD-R question

And are you saying that a 534 minute CD will not survive as long as an 80 minute CD, all other things being equal?

That is an interesting question. I would suspect that the likelihood of the 80-minute CD being useable is higher than the 534 minute CD because in 50 years someone will try and play both in a CD player and when one plays and the other one doesn't they may assume that the one that doesn't play is no good and dispose of it.


I realize that putting it into a PC drive and reading it would quickly educate the user, but I fear the least-common denominator when it comes to technical savvy in at least some archives. Many archivists try very hard to keep up with the technology, but archivist salaries are, sadly, rather small in many places and their workload is heavy.

When tapes started to squeal, many got dumpstered as "unplayable" with no recovery attempt made.

So, I do think that it is not as safe to leave a non-mainstream CD around in an archive.

As to the survival of the two from a photo-chemical perspective, I think that Jerry has provided information about what that depends on. Disc type, storage conditions, and quality fo writer are all key.

The other thing to worry about with the compressed audio CD-ROM is that you will need to have the proper codec to extract the compressed files. With WAV files, while you need a codec, it is the simplest variety. MP3 will be decodable, I suspect, longer than many other formats.
