  • Method for sensing position of magnetic tape during discontinuous travel of the tape
    Patent number: 5815336
    Abstract: A method for sensing the position of a magnetic tape during a continuous travel of the magnetic tape in a video cassette recorder. The method is particularly applicable to a VCR which includes a capstan motor for feeding the magnetic tape in the video cassette recorder at a constant speed, a capstan motor frequency generator for generating a pulse signal having a value determined in accordance with a rotating operation of the capstan motor, a reel sensing unit for sensing a rotated state of a reel on which the magnetic tape is wound, and a microprocessor provided with a storage medium. The microprocessor serves to control the rotating operation of the capstan motor while detecting the number of pulses generated from the capstan motor frequency generator per revolution of the reel, thereby sensing the current position of the magnetic tape.
