ABSTRACT:
A magnetic head attachment structure for a photographic film comprises a head unit for supporting magnetic heads which read and/or write magnetic information to or from the photographic film. The magnetic head attachment structure also includes a pressure unit for supporting bubble springs which press a magnetic recording surface of the photographic film to the magnetic heads. The bubble springs have a first condition where they are able to contact with the magnetic heads allowing the film to pass therebetween and a second condition where they are able to be selectively apart from the magnetic heads so that a pressure unit is able to rotate around the head unit on a shaft.
