ABSTRACT:
A method to monitor the relative position of a magnetic tape disposed in a tape drive, where that tape drive includes a first tape reel motor and a second tape reel motor. The method provides a magnetic tape disposed on a first tape reel, and releaseably attaches the first tape reel to the first tape reel motor. The method further provides a second tape reel attached to the second tape reel motor. The method operates the first tape reel motor and the second tape reel motor to transfer the tape from the first tape reel onto the second tape reel while maintaining a running second reel rotation count. The method sets a second reel rotation count limit, and determines if the running second reel rotation count exceeds that second reel rotation count limit. If the running second reel rotation count exceeds the second reel rotation count limit, then the method discontinues operation of the tape reel motors.
