Mmm, don't know one offhand. You might go to stacks of technical magazines
like EDN or Electronic Design. EDN does a yearly index of articles each, um,
January I believe. Shouldn't take two or three peeks before… oh heck, I'm
being silly, hold on… <flip flip scrabble flip>… aha, okay, here.
Grab a copy of Electronic Design, January 24, 1985. Page 186 is a nice
single-sheet summary of the three methods of storage (FM, MFM, and RLL). It
exists within a larger article on disk drives.
Since you're into disks, you might also take a look at IEEE Spectrum, June
1986, page 32 on, if they have it. An interesting article on copy protection
as applied to disks… basically a catalog of available techniques.
Yell if I can be of further assistance.
