I'll see if I can unearth some dates/names. I seem to remember a couple of 
working projects based around non-flying heads and mounting of commercial 
magtape onto a cylinder for the storage medium. Longevity is obviously 
questionable, and rotation speed would be rather limited!

Will's project is very much in a different league, obviously - hence my 
interest in how he gets on. To my knowledge, re-coating a non-contact drum 
running at 'commercial' speeds (what, typically in the 1500-400rpm range?) 
would be something of a first.

Oh, I once read a book describing a homebrew drum in it - I think it was based 
around using a tin can for the drum, and the capacity was in the tens of bits. 
(My brain wants to say it was "how to build a working digital computer", but I 
could be wrong there). I wonder if anyone ever actually built one that worked? :-)
