A miniaturized video tape cassette having flangeless tape winding hubs. Each hub is composed of an inner drum loosely fitted within an outer drum with torque transmitted between the drums via arms extending from the inner drum and fitting into corresponding slots in the outer drum. A groove is formed between the inner and outer drums which is disposed around a cylindrical support extending from the lower cassette half. Teeth are provided in the hub and cassette which engage to hold the tape stationary when the cassette is not in use. A spring biases the hubs towards the engaged position except when the cassette is loaded with into a video tape machine in which case the hubs are lifted away from the teeth of the cassette.read more
