Good one. People get more and more fancifully creative in the fictitious ways they concoct to suggest that any given magnetic storage device actually has infinite capacity.
Not ficticious at all to recover data this way, Randall. See http://www.cs.auckland.ac.nz/~pgut001/pubs/secure_del.html for just one of many references google finds. Despite your assertions, I am not suggesting that any given magnetic device has an _infinite_ capacity. That'd be silly. ;-) With the drive's internal r/w heads, the capacity is fixed. However, when you then read _all_ the data with a far more accurate and tiny read head (the microscope), you have access to data that the normal large head can't differentiate between. Mark
