Fascinating photos and videos with microscopic view of record grooves. Electron microscope images:  More here

It's a wonder that vinyl works at all! A bit like the internal combustion engine - if they did not exist, and you wrote a proposal to develop one: "OK, you are going to have 10 gallons of highly flammable liquid, squirt it into a cylinder with air, and make it explode with a spark? You must be mad!"
Imagine you are presenting a proposal to financial supporters to develop the vinyl record: "So you are going to press a groove into plastic to represent music, and then scrape a piece of diamond along the groove? The process is going to generate so much friction that the diamond is almost at red heat? And the plastic actually melts at the point of contact and then recrystalises? Hey hold on - the noise limit is close to molecular dimensions?? What makes you think this is ever going to work?"

Agreed
No way that will work, and no one will buy it anyway

I've seen various photos like this on the web recently. Like Craig, it baffles me how it even works at all - a squiggly groove set in plastic being able to reproduce instruments and voice with stunning clarity? I know you can say a similar thing about digital music being reproduced with 0s and 1s, but the vinyl format will always have my respect because technically speaking it should sound awful!
