Zany measurements and theories


I have to say that I do accept stylus drag exists, however where on earth do people get:
1. Stylus getting to temperatures that can melt vinyl - if so we'd never play out records more than once
2. Our records get hit with tons of pressure - if so why are none of my records smashed

From a theoretical standpoint, the real issue here is what Rodman9999 points to; how much heat is actually transferred from the stylus contact point (very small) and the vinyl (which is only in contact with the stylus for what I would venture to guess is milliseconds at a time). Also the elasticity of the vinyl, how that varies with temperature, and it's heat transfer properties.

OTOH, the empirical evidence he presents gives me a high degree of confidence that the interaction of those variables in real-life situations is such that this is a non-issue. Thanks, Rodman. Very important information.

What empirical evidence?
The empirical evidence is that no one has reported any ill effects attributable to repeated playing using better quality equipment properly setup.

As a precaution I never play my records because there's no telling what damage dragging a rock on a stick thru a jellified oil compound can inflict. Be afraid, very afraid.
Empirical evidence(empirical data, sense experience, empirical knowledge or the, "a posteriori") is a source of knowledge acquired by means of observation or experimentation. ie: The second 50% of my last post(my personal experience/observations). Of course; accepting those conclusions would depend on one's confidence in my aural acuity, experience with sound/music and powers of observation. Happy listening!
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.
