More reports-How many corrupted CD-R's with time?

Just in case any body is following this with any of the interest I am that the onn line mag audioreveloution.com that a checmist caim out with claim that magentic tape if not overplayed can saty in an archival state for 30-100 years.Claimed that a failure after 5 years of CD-R's would not be uncommon.So thought old mid 80's tech that Sony had that gave 16/44 on VHS tape may have been optimal.If anybody knows of data back devices fopr comecial ap's come to micd and would fit the bill let me know.Am really bummed that as was another person here who archived his vast cassestte collection but gave away originals has had problems after 5 years.I also think all these folsk who have hard disc loaded Ipods are going tom have all that .99 cent dowload money go down the tubes because eventually the bearings will go (or another problem will develope)in any hard drive if played enough.I think that some folks expecting CD peformance after the first corrosion problems were worked out and CD's have been if trreated gingerly (perfect".Many folks a few years down the line could have theoretically $10K worth of songs go down the tubes.Look LP's degraded after times (that's why I use LAST perservative.An independent source (from LAST ) Mike head tech at VPI told me that he could have an LP brought to him at a show and if treated with LAST preservative it sounded like it had half a dozen playes not the hundreds the owners claimed.Has worked fine for me an does retard wear.Well ahes top shes dust to dust is what most of us come to terms with just preferring it comes latter than sooner.

Interesting article concerning this subject on enjoythemusic.com under: Boston Audio Society/CD-R Errors--A Worrisome Trend. Actually kind of scary....worth a scan.

Wondering how optical hologram 1 TB discs will fair versus CD-R's.Laser will switch holograms to 1/0's in 60 layers if I remember right with no reflective material (you can see through them).How stable (interview with New York research company say's better).Should be on market in two years at huge price meaning they will be business only for a while.But this could be a big change.

I have had CDR's go bad, usually when left in the car in extreme temperatures. What do you expect? It is a practically disposable medium with no thought paid in design toward archivism.

Your right there.Crystalline metal that is meant to be "altered" (burning right?).If you go to a kid in the know at a best buy they will tell you no video on optical discs or DV will last as long as best tape formats which are stored in cool dry place (plastic bag with silicate say or even a bag of boil in bag rice).Then you need to have second copy to play and one to archive.I have thought about and if one is serious about keeping CD (or LP recording) redundancy or defense in depth.Get DVD clamshells for two CD,make label for outside with code near center if worried about dye problems,make one full WAV copy and on second CD make a copy or multiples of compressed files you use say one FLAC that you use and one in 320 etc.Then you get one you won't play and back up for a Hard Drive copy of one or both compressed file formats because as they say there are two Hard Drives.Ones that have died and ones that haven't.Given some of my CD's are now impossible to find or ones I have downloaded might not be borrowed or downloaded leaving it up to just a HD is a risk.Yeah cost for this might be nuts for a CD which will always be in print for some artists but if I could find a lent copy of "Pee Wee Ellis and Horace Parlan 'Gentle Men'" used for $65 (or $100) doubts are I would find another.Wouldn't want to take bought copy for driving and if I got a DL or a borrowed copy might not ever find again.Ones you might count on like the 60 plus Grateful Dead "Dicks Picks" many are now OOP and go for big $$$ so unless it's Led Zeppelin or Babs Streisand don't count on it being out there.And I have friends who I pass on OOP stuff to and the costs of two discs and a clamshell is way they can have multiple backs up's for the computer or HD which can go kabloo-ee and time.
