Abstract
An apparatus includes an optical data storage medium comprising a longitudinal portion at a resting location and a counterweight attached to the optical data storage medium. Unless the longitudinal portion is locked in place, the counterweight causes the longitudinal portion to move from the resting location when the optical data storage medium is rotated thereby rendering at least some data on the optical data storage medium unusable.
