Thinking about it some more, the
loading of the head against the surface on both sides is almost certainly
critical, so this wouldn't work :(
I've often wondered if one could make up a drive with less head pressure,
possibly using some additional electronics to clean up the signal - I've
had a few systems come in where people wanted the data recovered, and
they've been suffering from the "circular rings of death". Never explored
the idea further.
Regarding Als idea of reading the disk backward - It would be a fairly
simply matter to make up a version of ImageDisk which reads from the
inside out.
