摘要： A virtually transparent magnetic layer is included as an additional layer in a photographic film strip. Information exchange between various users of the film such as, for example, the film manufacturer, the camera user, the dealer and photofinisher, is facilitated by plural longitudinal magnetic tracks on the film that begin and end within individual frames. Each track is dedicated to the writing and reading of a predetermined set of parameters relating to the corresponding frame, for easy access by a particular one of the various users. Each user has the capability to read and/or write informaton in self-identifying data fields in the corresponding tracks.

摘要： A magnetic layer is included as an additional layer in a photographic film. Information exchange between various uses of the film, such as the camera user, the dealer and photofinisher, is facilitated by recording data in dedicated frame-limited longitudinal track(s) in said film. All data is recorded on the film using a self-clocking three-part code in order to provide automatic data synchronization between the various users without requiring film transport at the same speed or even a uniform speed when reading and writing data. Three-part encoded binary characters uniquely representing start and stop sentinels respectively, are recorded at the beginning and end of the track respectively and facilitate automatic detection of the direction of film strip transport.

摘要： The reliability of data transfer between stages of photographic filmstrip use and processing is enhanced by magnetically recording a limited data set repetitively along a wide track in a frame of the filmstrip. Plural laterally offset magnetic read heads monitor the data in the magnetic track and provide output data signals on parallel independently operating channels. The data content of the output data signals is examined to determine whether the data of an individual data signal contains corruption error. The combined linear and parallel redundancy of the system tends to ensure successful data transfer despite a less than perfect head-to-film interface and other data corrupting influences.

摘要： A virtually transparent magnetic layer is included as an additional layer in a color negative film. Information exchange between various users of the film--such as (for example) the film manufacturer, the camera user, the dealer and photofinisher--is carried via plural longitudinal magnetic tracks on the film that begin and end in individual frames. Each track is dedicated to the writing and reading of a predetermined set of parameters related to the corresponding frame. The photofinisher-dedicated tracts fill the exposed image area of each frame. The camera-dedicated tracks lie along the edges of the film between the film perforations, the perforations being widely spaced for this purpose. All data is recorded on the film using a novel self-clocking code which is completely self-clocking, in order to provide automatic data synchronization between the various users without requiring that any of them to transport the film at the same speed or even at a uniform speed when reading and writing. A start sentinel character and stop sentinel character, each having a predetermined self-clocking encoded binary bit sequence, are placed at the beginning and end of each track respectively, and facilitate automatic detection of film transport direction.

摘要： Electrical circuits suitable for encoding a binary data stream into a tri-bit code format. The circuits are particularly valuable for situations where the encoding or information transfer rate is dependent on unpredicable and variable transfer rate velocities and accelerations. The circuits provide "self-clocking", which, in turn, permit velocity insensitive encoding.

摘要： Magnetic recording apparatus for a photographic still camera comprises a magnetic head mounted on a flexure attached to the rear door of the camera. The head is positioned so that when the rear door of the camera is closed, it will enter an opening in the cartridge lip and engage the film. The portion of the lip and the plush material underlying the film provides a complient support for the film.

摘要： Data is recorded on the film by the manufacturer prior to exposure at a first magnetic head azimuth angle. The camera magnetically records information on the film frame-by-frame at a second head azimuth angle with each exposure or shortly thereafter. Before exposure of any frame, the camera determines whether the frame has already been exposed by sensing the recorded signal amplitude at one of the two magnetic head azimuth angles. In order to prevent a double exposure, the camera transports the film past any frame having data magnetically recorded therein corresponding to the second azimuth angle.
摘要翻译： 在第一磁头方位角曝光之前，制造商将数据记录在胶卷上。 相机以每次曝光或不久之后不间断地以第二头方位角逐帧地记录胶卷上的信息。 在曝光任何帧之前，相机通过在两个磁头方位角之一处感测记录的信号幅度来确定帧是否已被曝光。 为了防止双重曝光，照相机将胶片通过其磁记录在其中的具有与第二方位角对应的数据的任何帧传送。
