The inventon relates to a method and apparatus for marking or recording patient-related information and other necessary data in connection with X-ray imaging on a certain section of a film (6) by using a marking apparatus (2) which is movable relative to film (6). In the method, markings are made latent on film (6) in a manner that the markings become visible in connection with film development. The marking is effected as a sequence, line-directed deviation of a marking being obtained by moving the marking apparatus and the film relative to each other. The marking apparatus (2) used in the method is provided with marking elements which are brought into contact with film (6) for producing a marking on film (6), vertical deviation of alphanumerical marks included in a marking being achieved by individually controlling the operation of each marking element included in the marking apparatus. The marking apparatus of the invention includes marking elements and actuators for bringing the marking elements into contact with film (6) for marking the film. The apparatus further includes carrier assembly (8-10) for moving a marking apparatus (2) in the longitudinal direction of a slot (3) made in a film cassette (1).
