Automatic Unthread to Secure Tape From Sticking to the Head

A system and method for automatically unthreading a tape. The system and method determine whether the drive being at the stop state could cause the tape sticking condition in future after a defined dwell time (e.g., 20 minutes). The tape sticking tends to increase with time and humidity. Moreover, i...

Summary:A system and method for automatically unthreading a tape. The system and method determine whether the drive being at the stop state could cause the tape sticking condition in future after a defined dwell time (e.g., 20 minutes). The tape sticking tends to increase with time and humidity. Moreover, it is known that worn tape is stickier than new tape. With a plurality of attempts (e.g., four attempts) of moving tape (e.g., every 5 minutes), the drive is able to identify whether the tape needs to be unthreaded. Such a system allows a tape drive to handle the tape in safety at severe condition for the sticking tape, and minimize the penalty for the response to the command in normal condition.
