Patent abstract
In a method of electronically measuring reel off-center run-out and reel hub mismatch, tape speed data related to a tape coupled with an operating drive reel is electronically measured. The tape speed data is correlated with drive reel rotation angles. The correlated tape speed data is translated to drive reel hub radii variations with respect to the drive reel rotation angles. The drive reel hub radii variations comprise an operational measure of reel off-center run-out and reel hub mismatch of the drive reel.
