DNA would be a digital format (2 bits/letter).

Yes FM has been used to record the sound track in "Hi-Fi" VCR's and reportedly some of these machines sounded rather good.

It wouldn't be LM318 based record play electronics as found in Ampex ATR's. That would be equal to a programmer relying on a Commador 64, about the same "vintage".

What ever it could be, it won't be. Market forces have left the arena...

Now, how about that new 2 buck codec?

Seriously, with good effective assemblyprogramming then a modern machine would be idling constantly.

But that's not the question.  I don't care about market forces.  Let's leave that out of the discussion completely.  The question is, what could be the best analog recorder.  What technology could be employed now - today - to build a machine that would be a superior analog audio recorder.  If it uses tape, then fine but don't be caught up with involvement in tape.  Go a completely different route.  "Think different"(ly).

You mean, think "outside of the box"?

Someone made an mp3-player on the Commodore 64 last year.
A friend of mine figured out how to make a reverb effect on the Commodore 64 half a year ago.
There is a Twitter client for Commodore 64.

It's wicked crazy how people keep breaking boundaries on old computers.

Weren't the Apollo missions done with onboard computers with the processing power of modern calculators?

What do you want it to do?  As Bruno mentioned FM if given wide bandwidth can provide a very large dynamic range, etc.  You would still have other things like time-base errors, but maybe they can be reduced.  No "fun" aspects like we get in tape compression, of course.

It's all about the storage medium.

What are the attributes of a great analogue recorder? Are you talking specifically in regards to recording music?

The idea would to be to record music.  It may not be more than a two-track recorder.  I'm trying to explore the idea as to where analog music recording would be today had digital not come along.  Would we still be using tape.  What developments in the last 50 years would have we employed.  That sort of thing.

I admit FM audio recording is a great idea which had fallen out of my memory some time ago.  But when you look at recording media over the years, which have we not pursued?  What could be great if someone were just to try  it?  It doesn't have to be cost-effective, because in the beginning it seems no technology is.  I just want to explore how great analog recording really could be.

This may be a dumb question but, is non-linear analogue recording possible? If it were then wouldn't that have been the logical progression?

You can make any analog recorder a "non linear" recorder. Just shut off the bias oscillator.

Even with proper alignment, you won't get better than 4~5% THD at 100 hz and 10k hz on any analog recorder. I would consider that non linear compared to converters with .0005% THD.

Now, how about that 2 buck codec?
