Re: [ARSCLIST] The ways CD's and DVD's can fail.
Roger,
Thanks for the info. I'll certainly keep it in mind if I buy or resell any
old CD's. I believe there are lots of people who still don't know about
this. See also my reply to Mike, also posted today for more comments.
Sincerely,
Ron

This is all very old news,that has been discussed for years since the
early 90s,in regards to CDs.I can't speak for DVDs,but I would imagine
it's very similar.I first read about this probem, in "Goldmine",and "The
Absolute Sound",two magazines well known for their anti-CD bias,where it
was discussed extensively.There were pro-CD advocates,who called us
alarmist and luddites,but the increasing number of CDs from the 80s,that
are now unplayable bear us out.
I have tried selling older CDs ,on eBay,and I must say it's a crap
shoot.Earlier this year,I sold one of those pre-1986 Columbia Paul
McCartney CDs,pressed by Sony in Japan.It was returned to me as
unplayable.Before I tossed it out,I popped it in my computer to play
it.Indeed there were large sections of the CD,where there was dead
silence. Comparing the surface to a new CD,there was indeed subtle,but
noticeable discoloration.Was this caused by oxidation,or electronic altering ?
The collector CD market is going under,but it is still there for now. I
would never recommend selling an older CD without playing it
first.Lamination peel,and leaching of paint into the disc's playing
surface are both very common problems.
I remember encountering the latter problem as long ago,as 1989,when I
worked in a record store,and bought used CDs.
The archival quality of gold as a medium,is well established,and companies
who make audiophile CDs that sell for 4-5 times what a regular CD
does,have been using 24k gold on thier CDs,since about 1988-89 or so.
