发明名称 Camera with magnetic recording apparatus wherein relative positions of a magnetic and a recording head are set with precision
摘要 In a camera using a film with a magnetic recording portion, two film guide members restrict displacement of the film in a direction perpendicular to the moving direction of the film, and a magnetic head magnetizes the magnetic recording portion of the film. A magnetic recording current is output to the magnetic head at a predetermined magnetic recording density D. The magnetic recording density D satisfies D</=K.l/( DELTA /W) where l is the length of each of the film guides, DELTA is the difference between the width of the film the distance between the two guide members, W is the width of a recording medium of the magnetic recording portion, and K is a constant.
