Abstract
The position of the tape in a magnetic tape recorder is obtained by counting the pulses derived from the revolutions of a reel or spool. The ratio of the number of revolutions per minute of the reels and the total number of turns is determined by means of a test run; the counting process is linearized by means of these values.
