ABSTRACT:
A videotape tape guide for guiding videotape in a videocassette. The videotape tape guide is comprised of an elongated cylinder having first and second open ends. A groove extends longitudinally from the first open end of the elongated cylinder to the second open end of the cylinder. The longitudinally extending groove allows the material required to form the tape guide to be reduced, thereby reducing the cost of the tape guide. Further, the groove allows firm seating in the videocassette to prevent rotation of the tape guide when positioned therein.
