Running for Dummest question EVER


Is there (or could there be) such thing as High Definition Analog recordings and music reproduction, bear with me for a second, a process to engrave and read vinyl that would be in the nano tolerance. Forgive me if this is totally ridiculous but just curious to hear opinions.

Pardon me,,,I should have added that doesn't mean that records can't sound fantastic,,
half speed mastered is what you are looking for. The vinyl is cut at half speed so the sound are more accurate. Good luck finding one however, I do not think they make them anymore.

tks, this is part of what I was looking for...would there be such thing as a more precise cutting tool or cutting process that capture more subtle freq or volume changes of the recording? same for the reading, I know there are laser LPs, is this waht they are trying to do?

Yioryos:
Tks, send me an email to tell me who you are on CAM but no need to worry I am still there, just in a different suit!!!!
"good luck finding them" Ebay is awash in them (Mobile Fidelity Sound labs, Nautilus, Direct Disc labs, etc. half-speed mastered LPs). You'll pay more than in the early 80's however.
