Method and apparatus for calibrating a tape transport servo system

A method for calibrating a tape transport servo system for a tape drive is disclosed. The tape reel motors are excited when the tape drive is not being controlled by the tape transport servo system. Then, calibration data is collected for the motor torque, motor friction, DAC offsets, and pulse widt...

Summary:A method for calibrating a tape transport servo system for a tape drive is disclosed. The tape reel motors are excited when the tape drive is not being controlled by the tape transport servo system. Then, calibration data is collected for the motor torque, motor friction, DAC offsets, and pulse width modulator control signal timing.
