摘要： A photographic still camera for receiving an elongated filmstrip having a cross-curvature in the cross film direction across said filmstrip and having a substantially transparent magnetic layer deposited on the film surface and for recording or reproducing information on or from the magnetic layer in the image area in and relation to the exposure of image frames of the filmstrip. A magnetic head is formed of a plurality of frustums including inner frustums supporting a plurality of active head gaps in an interior region and at least one further outer frustum on each side of the inner frustums in the cross film direction. The frustums and active head gaps have a contoured height profile in the cross film direction positioned to penetrate the film plane and to wrap the filmstrip around the frustums in a cavity in the film transport path, the contoured height profile in the cross film direction ensuring elastic compliance of the active head gaps with the magnetic on film layer tracks, with or without applied film tension or film compression. Contouring is effected by lapping the head mounted in the film transport path to approximate the cross-curvature of the filmstrip.
摘要翻译：一种照相静态照相机，用于接收在横跨薄膜方向上横跨所述胶卷并具有沉积在胶片表面上的基本上透明的磁性层并用于在图像区域中或从磁性层记录或再现信息的细长胶片与影片的图像帧的曝光有关。磁头由多个平截头体形成，包括支撑内部区域中的多个有效头部间隙的内部平截头体和在横截面膜方向上的内部截头锥体的每一侧上的至少一个另外的外截头锥体。截头锥体和主动头部间隙具有在横向膜方向上的成形高度轮廓，其定位成穿透膜平面并且将胶片包裹在膜输送路径中的空腔中的平截头体周围，横截面膜方向上的轮廓高度轮廓确保弹性活性头间隙与磁性膜层轨迹的一致性，有或没有施加膜张力或膜压缩。轮廓通过研磨安装在胶片传送路径中的头部来近似胶片的横向曲率来实现。

摘要： Magnetic recording and/or reproducing heads particularly for use for recording and reading information on a magnetics-on-film (MOF) layer in the image area of photographic filmstrips exhibiting a cross-film curvature in cameras or other filmstrip handling apparatus. A magnetic record/reproduce multi-head array is formed of a plurality of magnetic head elements mounted to extend across the width of the filmstrip and across the filmstrip image frame area, each head element contacting the magnetic layer at a predetermined cross-film position in a film transport path. The surfaces of the head elements aligned to contact the filmstrip magnetic layer are burnished or lapped by an abrasive tape lapping of the head as a final contouring operation on the head to remove all edges that can scrape or scratch the magnetic surface of the filmstrip. An elongated, compliant backing support, e.g. a free wheeling roller, pad or brush, having a low friction contact surface, is positioned to bear against the filmstrip emulsion layer opposite to the multi-head array. Light pressure is applied through the backing support to conform the filmstrip magnetic layer to the magnetic head elements in the cross-film and film advance directions.

摘要： A photographic still camera for receiving an elongated filmstrip having a cross-film curvature and having a substantially transparent magnetic layer deposited on the film surface and for recording or reproducing information on or from the magnetic layer in relation to the exposure of image frames of the filmstrip. The filmstrip is transported from supply to takeup chambers between film rails and a backing plate past a camera image frame exposure aperture with the magnetic layer facing the backing plate and having a concave cross-film curvature across the image frame area. A magnetic recording multi-head array formed of a plurality of recording heads mounted on flexure elements of a flexure support is positioned to extend across and contact the magnetic layer in the image frame area at the side of the exposure aperture. Each flexure element includes an elongated, cantilever spring fixed at one end to the backing plate and terminating in a mounting platform having a gimbal mechanism for providing pitch and roll compliance with film motion and the cross-film concave curvature. Each magnetic recording head element is shaped with contoured profiles in the cross-film and film transport directions for ensuring compliance with the filmstrip magnetic layer during roll and pitch motions of the magnetic recording head without causing damage to the filmstrip.

摘要： A photographic still camera for receiving an elongated filmstrip having a cross-film curvature and having a substantially transparent magnetic layer deposited on the film surface and recording or reproducing information on or from the magnetic layer in the image frame areas of the filmstrip. The filmstrip is transported from supply to takeup chambers between film rails and a backing plate past a camera image frame exposure aperture with the magnetic layer facing the backing plate and having a concave cross-film curvature near one side of the exposure aperture. A plurality of inverted gull wing shaped, spring flexure elements are positioned to extend across the magnetic layer at the side of the exposure aperture. Each flexure element has a fixed mounting plate attached to the backing plate coupled through an angled fixed leg to a mounting platform which in turn is coupled through a further angled leg back to a further plate such that the mounting plate is suspended toward the filmstrip magnetic layer. Magnetic recording head elements mounted to the mounting plates contact the magnetic layer across a variable spacing. Pitch motion is provided through the flexible legs in response to changes in filmstrip advancement tension. Roll motion compliance with the concave cross-film curvature is provided by a mounting platform gimball mechanism.

摘要： A print head applies electrical energy to an electrically resistive and grounded transfer ribbon bearing heat transferable dye, during sliding pressure contact and relative movement between the head and ribbon, for resistive heating of the dye to a transfer temperature for transfer to a receiver to form images of selective pixel size thereon. The head has a row of electrodes with end faces and an electrically non-conductive substrate with an end face, the end faces lying in a contact plane for contact with the ribbon. A groove in the substrate end face separates such end face from the electrode end faces. The width of the groove is sufficient to inhibit heat transfer at the groove from the ribbon to the substrate for controlling the dye amount heated to transfer temperature adjacent the groove during the relative movement and in turn the image pixel size.
