I have CDs I burned 15+ years ago that are perfectly fine. They are stored in cool temps and away from UV light. I have a cd burned a year ago that sat near a window and is unreadable. It was a temp need so nothing was lost. Storage of burned optical media is the key to their longevity once the media quality is stable.<br><br><div class="gmail_quote">On October 29, 2015 3:29:13 AM EDT, Steve Litt <slitt@troubleshooters.com> wrote:<blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">

talk of quick CD/DVD decay just doesn't match my<br />experience.
