What about the heads from disc drives? They record at densities that must be way beyond audio to cram the data they do onto a couple of platters, and this was 15 years ago.

I suspect that for digital they are designed to work in a narrower range of (high) frequencies and so wouldnt work well for analog which requires heads able to be reasonably linear across the full audio spectrum.

Re: Reel to reel revival?
It's well known that the width of the gap in a tape head sets the high frequency roll-off characteristic. Less well known, the total length of the pole pieces in magnetic contact with the tape sets a low-frequency roll-off.
Heads for recording data also don't need to be particularly linear. narrow track-width to squeeze in thousands of tracks on a platter is more important than very high signal to noise ratio. I think the design of disc drive heads has diverged a long way from audio heads. However, some of the technology employed to make them could make for some rather interesting possibilities in audio heads. David
