Abstract

PURPOSE: To make the tape tension constant without complicated arithmetic operation even at a high speed tape running by calculating the radius of a supply tape based on the result of detection of the drive speed of both reels so as to control the supply reel motor.
CONSTITUTION: Drive speed information detectors 7, 8 detect driving periods ts, tv of supply/winding reels 2, 4 respectively and a supply side tape radius calculator 9 calculates a radius rs of a tape 1 of the supply reel based on equation. A reel motor 5 is controlled via a supply reel motor drive control circuit 10 in response to the radius rs and the tape tension is controlled to be nearly constant even at the fast forwarding. In using the reels 2, 4 for the winding and supply reels respectively, the similar circuit is used to obtain the similar result, then no complicated arithmetic operation is required even at high tape running such as fast forwarding or rewinding to make the tape tension constant thereby stabilizing the tape running. In equation t0, r0 are driving periods at capstan feeding.
