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.

That's what MFSL Records were all about. Most information in a given space, like the Track Record.
Can a record be considered hi-def with such a limited freq response, high background noise and poor channel separation??? That's like saying black and white tv's are great because they do such a great job on grey-scale. IMO
Now if you're talking high quality (studio grade)analogue tape that's a different matter.
Pardon me,,,I should have added that doesn't mean that records can't sound fantastic,,
