Great idea for recording.
Now we just have to invent a reading system...

Use fixed font.

They seem to have three distinguishable levels of magnetization,
so about 1.5 bits per cell.

Pointing magnetic sensors? Thin beams? Unknown to me.
Array of (non-thin beam!) sensors + tomography? Might work.
Glad I'm retired, this looks too much like the DocData optical tape storage I worked on.

I once did read about 3D storage with lasrs in some crystal or something.. >> No idea if that ever came to market.
And storage in DNA...
Here are a couple of early review papers on holographic recording:

Oh no! You have just reminded me of "The Stone Tape" by Nigel Kneale.
I used to have nightmares about that.

LOL, just did read the wikipedia article on it:

Have not seen it, there are so many? things 'ghost' related,
'Ghostbusters' I have seen is one of those.
I have never seen a ghost myself though.
I knew somebody who claimed to have seen some at a burial site...

"The Stone Tape" is completely different, it's just ordinary technology >researchers trying to go about their business and stumbling over

It depends what you mean by 'ghost' - I have never seen a gliding figure
in a white sheet moaning "Whooo!" but I have seen some very strange
things that are not accounted for by conventional knowledge. I have
also experienced an overwhelming feeling of dread in one particular
location -- many years later I mentioned it to a friend and found she
had had exactly the same experience at the same place.
A week after our mother died, my sister and I both had a very strange >experience. She sounded me out cautiously, in case I ridiculed her, but
I knew exactly what she was going to tell me and confirmed that it had
just happened to me too.
