摘要： To obtain the correct tape wrap angle at the head in a cassette loaded recorder, tape guiding support "outriggers" integral with the head assembly are provided. The outriggers are located on either side of the active portion of the head structure to guide the tape and to establish the tape/head wrap angle independent of the exact locations of the cassette guides. Slots separate the active head structure from each of the outriggers, presenting an edge at each side of the head to skive any air film adherent to the moving tape as it approaches the head's transducer. Additionally, the entire head and outrigger structure is fabricated from the same or mechanically similar materials and has an overall constant area profile contour which wears at a uniform rate due to tape abrasion.

摘要： In a recorder having two inline heads, such as a record head followed by a reproduce head, it is necessary to insure adequate tape wrap angle at the transducing element of each head. Because the tape is spanned between the two inline heads, the tape leaves the apex of one head at a zero wrap angle and arrives at the apex of the second head with a zero wrap angle. The invention provides outriggers on each head assembly which guide the tape, and teaches placing each transducing element off the apex of its head assembly to maintain adequate wrap angles at the transducing elements of each inline head. The outriggers are provided with slots which skive entrapped air to prevent tape "flying" with attendant loss of contact with the transducing elements. The contours of the outriggers and the lands on which the transducing elements of each head assembly are located form constant area profiles to provide constant wear characteristics for the head assemblies.
摘要翻译：在具有两个内联头部的记录器中，例如记录头，随后是再现头，必须在每个头部的换能元件处确保足够的胶卷包角。由于磁带跨在两个内嵌头之间，磁带以一个零包角度离开一个磁头的顶点，并以零包角到达第二磁头的顶点。本发明提供了引导胶带的每个头部组件上的支架，并且教导将每个换能元件从其头部组件的顶点放置，以在每个内联头部的换能元件处保持足够的包角。外伸支架设置有槽，其夹入空气以防止带状物“飞行”，伴随着与换能元件的接触失去接触。外伸支架和每个头部组件的换能元件所在的平台的轮廓形成恒定区域轮廓，以为头部组件提供恒定的磨损特性。

摘要： A magnetic read/write head suspension assembly for achieving high magnetic head compliance with at least one edge track of the MOF layer of relatively stiff photographic filmstrips particularly during photofinishing operations. The filmstrip has an emulsion layer side opposite to the MOF layer side and exhibits a positive cross-film curvature toward the emulsion side when unrestrained. Filmstrip edge guides including parallel angled channels extending in a film transport path receive the filmstrip edge regions. One or more magnetic read/write head is mounted in the edge guides with the magnetic head gap length oriented in alignment with the angle of the MOF layer of the filmstrip edge region received in the channel and makes compliant line contact of the magnetic head gap with the MOF layer side in the edge region without imparting drag on the central region of the filmstrip. A backing support member formed of an elastic, deformable reed-shaped backing member trapped in a cavity of the edge guide is thereby biased in relation to the magnetic read/write head to make contact with the emulsion layer side of the filmstrip edge region. Channel angles of a positive 20.degree. to 40.degree. transverse to the direction of film transport plane of the filmstrip may be provided to receive an unrestrained filmstrip exhibiting normal, positive cross-film curvature. Alternatively, the filmstrip may be restrained to exhibit a negative cross-film curvature and directed into channels angled at a negative 3.degree. to 7.degree.. In this case, the backing support may be unnecessary.

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： A magnetic head assembly useful as a write head is formed with a ferrite substrate, having a recessed channel on one surface in which a conductive coil is deposited, and a ferrite closure having a planar surface that is joined to the substrate surface to establish a transducing gap and to enclose the recessed coil. In operation, pulsed write current is applied to the write head and a significant reduction in Joule heating is realized. A low resistance substrate is employed to provide a high saturation flux density.

摘要： Signal peaks are identified by measuring the slopes on each side of a signal peak. Each slope measurement is linearized to ascertain a slope angle. Both linearized portions and slope angles are compared to find an intersection of the linearized portions. Such intersection identifies the location of a single peak. The measurement method is particularly useful for detection of peaks in signals with low signal to noise ratios. A programmed digital computer may be used in the measurement method.

摘要： A magnetic recorder includes multiple permanent magnetic elements having magnetic orientations that impart a sequence of magnetic transitions to magnetic media of a photographic filmstrip contained within a camera. The permanent magnetic elements are external to the camera. The sequence of magnetic transitions comprise information that can be subsequently retrieved and provided to the photographic processor and/or photographer. The information can include identification of locale or other information of interest to the photographer. The magnetic recorder requires no power supply and is easily operated by a photographer virtually without regard to weather conditions.

摘要： Magnetic record/reproduce apparatus for recording or reproducing information on a magnetic layer of a filmstrip in a camera, and more particularly, modular magnetic recording apparatus for optional attachment to photographic still cameras. Power and control signals supplied from within the module define the format and content of information recorded or reproduced from tracks in a substantially transparent magnetic layer. In one embodiment, the camera contains a record/reproduce head in the film transport path. In a further embodiment, the module contains the record/reproduce head, and the camera is adapted to receive the record/reproduced head in a record/reproduced aperture and position it in the film transport path on attachment of the module to the camera housing. In both embodiments, the magnetic head is preferably an elongated multi-head element array. Preferably the magnetic head aperture of the second embodiment is shaped to receive the elongated multi-head array as either a single elongated opening or a row of individual head receiving openings aligned in the cross-film direction, and a light tight flexible, opaque membrane is stretched over the magnetic head aperature so that the multi-head array may be inserted therein and physically bear against the membrane and the magnetic layer of the film strip adjacent to the membrane. A further external movable door or cover may be provided over the magnetic head aperture that is movable out of the way when the module attachment to the camera is made.
