Motor control apparatus for reel-to-reel tape drive system

摘要

A motor control apparatus for an unbuffered reel-to-reel drive system including independently operable first and second drive motors including first and second sensors for detecting rotation of reels and a circuit for controlling the drive motors cooperatively to maintain tension applied to a tape. The drive motor control circuit controls the drive motors on the basis of a servo-mechanism control algorithm and a stop-lock control algorithm using control signals having hysteresis curves in response to position deviation and a transport direction of the tape.
