Zany measurements and theories

Records have been around for an amazingly long time and continue to sound good so I wouldn't lose any sleep over them not being indestructible.

If you wear one out and still must listen, time for a new copy. Nothing lasts forever.

Seikosha,

The thing is the highest temperature would be at teh point of contact between the stylus and the record due to friction there and dust tend to accumulate towards the front of teh stylus as it moves through the groove, not down there.

Its an interesting question what the temperature due to friction of a stylus moving through a record grove is but its mostly an academic one I think and not of much consequence, though I have no doubt if there were a way to keep it cooler without other negative effects, that could only be a + from a record wear perspective.
