ABSTRACT:
A registration pin for a rotating drum recorder device cooperates with a film to register and support the film during loading the film onto the drum. The registration pin has a reduced profile to reduce the overall size of the drum. The pin also has a construction to permit loading of different types of films onto the drum. The head of the registration pin is provided with a profile that supports and positions the film on the drum, even though the registration pin is shorter than conventional pins. The registration pin includes at least one protrusion to sandwich the film against the surface of the drum. The protrusion may take any appropriate form. The protrusion may include a "teardrop" shaped form, in order to positively hold the film on the drum.
