发明名称 Tape cartridge containing tape supply and take-up reels, recording drum and reel drive motors, obviating capstan motor
摘要 A small-sized light-weight tape cartridge to be installed in a recording and reproducing apparatus, for stably controlling a predetermined running speed of the tape. A clock signal is calculated from the photo-detected rotation of a reel in the cartridge by reading out from a ROM a count value per second corresponding to an accumulated counting value. The rotation speeds of the winding reel and the feeding-out reel in the cartridge are controlled so that the tape speed becomes a prescribed value. As a result, there is no need for a capstan motor, and the tape, a drum, the winding reel, the feeding-out reel and a control driving system are accommodated in a small-sized tape cartridge housing that is removably installed in the recording and reproducing apparatus.
