ABSTRACT:
The length of tape that can be wound into a videotape cassette such as Betamax or VHS can be increased by modifying the casette to employ the braking mechanism of the invention. This involves a flanged reel in which teeth are formed only in the outer face of one flange, and a brake lever which has a finger formed with a tooth-engaging ramp that is inclined at 30.degree.-60.degree. to the inner face of said flange when the finger fits between adjacent teeth.
