<p>PURPOSE:To stably record and read out information to/from the magnetic recording part of a film in respect to the film for a camera wide in its width and not stable in its flatness by providing a roller to guide the film so that the magnetic recording part of the film is brought stably into contact closely with a magnetic head. CONSTITUTION:The variance of a film position is removed by arranging the rollers 2, 4, 11, 13 for surely regulating the film position at both the sides of the magnetic head 9, and in addition, the pressing force of the head 9 to the magnetic recording layer of the film is increased by protruding the head 9 by l1 beyond the plane of the rollers 2, 4. Besides, usually the head and the roller are energized independently by each spring, but on the contrary to this, the positions of the roller and the head 9 can be surely positioned and fixed firmly at the time of the unit assembling of a base plate 1 by fitting the head and the roller to one base plate 1. Thus, the information can be stably recorded and reproduced to/from the magnetic recording part of the film 24 in respect to the film for the camera wide in its width and not stable in its flatness.</p> |
