ABSTRACT:
A reel speed servo for inclined recording tracks such as used in R-DAT. The two rotary magnetic heads are inclined at different azimuth angles. The relative speed between each of the heads and the tape is detected. Then the difference of these relative speeds is determined to thereby detect the speed of the tape, which is thus used in the reel speed servo.
