Claims
- 1. A tape speed control apparatus based on a reel drive for taking up a tape to a take-up reel from a supply reel, comprising:
- a servo circuit which causes the tape to run either at a first speed higher than a preset speed, or at a second speed lower than said preset speed in response to input of a speed change-over command signal;
- wherein both said first speed and second speed are higher than an ordinary playback speed;
- a speed detector which detects a current tape speed;
- a calculator which calculates a data representing a wound tape-quantity on the supply reel;
- a decelerator which decelerates the tape speed at a rate based on said data in response to a stop command signal; and
- a brake which stops the tape when the current tape speed detected by said speed detector is lower than said preset speed.
- 2. A tape speed control method based on a reel drive for taking up a tape to a take-up reel from a supply reel, comprising:
- causing the tape to run either at a first speed higher than a preset speed, or at a second speed lower than said preset speed in response to input of a speed change-over command signal;
- wherein both said first speed and second speed are higher than an ordinary playback speed;
- detecting a current tape speed;
- calculating a data representing a wound tape-quantity on the supply reel;
- decelerating the tape speed at a rate based on said data in response to a stop command signal; and
- stopping the tape when the detected current tape speed is lower than said preset speed.
