摘要: A method and apparatus for detecting computing tape reel radius using low-resolution angular position sensors is disclosed. Tape reels are driven at a constant velocity, complete resolution of the detected coarse commutation first reel, R 1 , second 2 calculated according to: =(( L*T/pi )/(1+ T /T )) 0.5 where L total length tape, thickness rotation time 1, 2. The calculation two low (one pulse per turn) results in great cost product packaging savings.
