Hello Phil - 

PM>  ------exploding CDs 

--8<--cut 

PM>> My thought exactly. You mean after all that trouble
PM>> assembling what I've been thinking of as my final and
PM>> permanent jazz collection, it's gonna spring a spider's
PM>> web of cracks and then crumble to dust? Sheesh. 

>> I had mentioned this aging process quite some time ago for
>> ALL plastics and everyone (then) insisted I was wrong.  One
>> of my former employers specialization was plastics
>> engineering. He told me that all plastic continually shrinks
>> although at a much decelerated rate after the first few
>> weeks and will return to various carbon compounds and
>> crumble. As I remember it he mentioned 10-15 years. I have
>> managed to keep various plastic objects for that long and
>> they do crumble if you try to disassemble them. 

>> I don't think sunlight is a factor but heat definitely is a
>> catalyst. 

PM> === Oh, no doubts here in Montreal about the weather's
PM> effects on the disintegration of plastics in general... 

--8<--cut 

PM> === But, as Roy pointed out by comparing CDs to vinyl
PM> records, I also got the idea that CDs were -the- stable
PM> repository for music -- at least more stable than anything
PM> else.

CDR to be more specific. CDRW are not as trustworthy long-term. 

As a sidenote I watched a documentary once of a Japanese
company that manufactured 100 year (guaranteed) paper for
writing contracts etc. on. I think they said they were working
on 200 year paper? They sold special ink for this too btw. :-) 

I hadn't thought of that before but around here I have 15-20
year old printouts that almost crumble if you try to unfold
them. :-\
