Hello Michael,

If you don't stop the disk during the whole read process, and sample at
a fixed rate, wouldn't your samples automatically be associated with a
(relative) rotational angle, with limited accuracy to be sure, but no
more limited than what any reliable copy protection scheme could rely on?

Or am I missing something here?
