Abstract: A photographic still provided with a magnetizable coating is inserted into a recording/playback device provided with a movably mounted head unit having a set of heads. A rotary motor drives an endless belt in a single direction, the upper and lower runs of the belt always travelling in opposite directions. The head unit is alternately coupled to the upper and to the lower run of the belt, for travel in one and then the opposite direction. Upon each reversal of the travel direction of the head unit, a successive one of the magnetic heads is activated, so as to track a meandering track on the magnetic coating.

Abstract: A novel film cartridge, camera for use with such cartridge and method of making such cartridge are disclosed. The cartridge is in form of a pocket of a material which is impermeable to light and which accommodates a multi-exposure film strip having a length at least equal to the length of the pocket.

Abstract: Recording medium for photographic prints comprising a magnetizable layer on the rear side of a photographic material which is preferrably paper based, the magnetizable areas having different surface roughnesses. This medium allows recording of sound information or codes on the prints and reproduction in recorders or by monitoring.

Abstract: A sheet of exposed and developed instant-camera film is discharged from an instant camera and then inserted by the user into a film-holding structure on the back of the camera which very accurately positions the film sheet, such that upon removal and reinsertion of the film sheet into the holding structure the film sheet will always assume a predetermined position. The camera is provided with a multihead magnetic head unit mounted for reciprocating motion along a magnetic strip or coating provided at a marginal portion of the inserted film sheet. During first-direction travel of the head unit, one head records, and during second-direction travel of the head unit a different and differently located head records onto a further segment of the magnetic strip. After recording, the recorded information, e.g., spoken words identifying the subject just photographed, can be reproduced, and if desired erased.

Abstract: A self-developing camera has a box-camera type housing in which there is room to store one or more spare film packs. The housing requires an absolute minimum of packaging for storage, transportation and sale.

Abstract: The reproducing apparatus, such as a motion-picture film projector, stops recording medium transport in response to interrupt-transport frame markings on the recording medium and reproduces the thusly marked image frames as still images. Interrupt-transport frame markings are provided at the terminal frame of each motion-picture scene on the recording medium, or at each still-shot image frame on the recording medium, or both. The user of the reproducing apparatus can select automatic reproduction of motion-picture scenes interspersed with automatic still reproduction of still shots, and can additionally select automatic still reproduction of the terminal frame of each motion-picture scene.

Abstract: The user of a motion-picture camera selects between motion-picture and single-exposure operation, and presses a release member to initiate shooting, letting go of it to terminate motion-picture shooting. Each time the user lets go of the release member, an internal device provides an interrupt-transport marking alongside the just exposed film frame, or phase shifted relative thereto. Alternatively, the interrupt-transport marking is provided the next time the user presses the release member. In this way, the terminal frame of each motion-picture scene, and each and every one of the interspersed single-exposure shots, is provided with an interrupt-transport frame marking. Thus, if the film is run through a reproducing apparatus provided with a marking detector, detection of each interrupt-transport marking during motion-picture reproduction causes the terminal frame of each motion-picture scene, and also each one of the still shots, to be persistently reproduced as a still image.
