A conventional video recorder has a top plate 2 mounting a tape supply spool 22 and tape take-up spool 22a upon a common shaft 19. A recording assembly 6 has a conventional video recording drum and combines with a master cassette holder 4 to complete a cassette recording station. A roller system guides the tape from the supply spool 22 through the recording station to the take-up spool 22a. Stepper motors 3 provide rim drive to the the spools 22 and 22a and vacuum troughs 8 and 9 and associated photoelectric devices provide for speed control of the tape transport functions as a whole to ensure that tape is conveyed at a uniform speed without slack. |
