Abstract
Disclosed is a method and apparatus whereby each time a tape is wound upon a prescribed reel, the winding pattern may be assumed to leave the array of tape edges in a unique 'edge profile' represented by the position of each winding edge as viewed from one side of the reel along a radial direction--this 'profile' being interpreted as a 'winding signature'; the signature may be detected photo-electrically and recorded in a convenient encoded fashion for possible use in uniquely identifying and documenting each unspooling/rewind sequence to thereby monitor tape use.
