摘要： A magnetic head and a method of producing a magnetic head for use with magnetic contact recording media which passes over the magnetic head in contact therewith, thus, exerting a pressure on the magnetic head. The magnetic head includes a transducer support (24) having a side with two generally coplanar raised elongated facing surfaces (54a, 54b) which have a space between them and are generally aligned along a longitudinal axis (62) which is transverse to the direction in which the media travels accross the magnetic head. The magnetic head further includes a core (26) located in the space between the two facing surfaces (54a, 54b). The core (26) has an elongated surface (56) which extends in the direction in which the media travels to a greater extent than at least a portion of the facing surfaces. The core also has a transducer element embedded within it. The combination of the facing surfaces (54a, 54b), the elongated surface (56) of the core (26) and the transducer element form a generally coplanar wear surface. The dimensions of the wear surface which extend in the media travel direction are selected to effect a predetermined wear of the wear surface as the media advances across the wear surface.

摘要： A magnetic information recorder/reproducer which can reduce the possibility of breakage of parts and thus lessen the trouble for maintenance. A resilient member for pressing a magnetic medium against a magnetic head has a resilient, hard guide layer provided on one side thereof facing the magnetic medium. The guide layer prevents the magnetic medium from coming into contact with the resilient member. The resilient member is thus less like to be broken or worn because it does not contact the magnetic medium.

摘要： A multiple channel magnetic tape head assembly (10) defines a plurality of spaced-apart transducer elements (24, 26) along an integral bar (12) of ferromagnetic material. Each element (24, 26) formed by grinding operations performed upon the integral bar (12), has a magnetic gap (28) and flux circuit which is isolated from cross-talk with the other elements. Each element is precisely located by the integral bar (12), portions of which remain after griding. The head assembly provides an aligned longitudinal tape wear region and may further provide widened transverse wear regions adjacent to each of the transducer elements. A fabrication method for forming a multiple channel magnetic tape head assembly is also described.

摘要： The invention relates to a tape recorder and/or playback device for a multitrack tape. The device comprises a magnetic head (13) having active parts for recording and/or reading microtracks, the active parts being arranged in a two-dimensional matrix within a substantially planar surface of the magnetic head and pressure means (16) assuring contact between the microtracks (2) and the active parts by acting on a back side surface of the tape (11) opposite to the front side surface the magnetic head is on. Means for moving allow to position the magnetic head in front of either one of at least two macrotracks bundling addressed microtracks. Means for supporting a portion of the tape surface adjacent to the macrotrack bundling the addressed microtracks prevent unwanted tape deformation.

摘要： The invention concerns a device which comprises means for displacing to transversely position a multitrack tape in front of a reading and/or writing head. The magnetic tape carries a plurality of elementary tracks which are grouped in several bundles. These bundles are selectively accessed using the means for displacing. The writing and/or reading head can write and/or read information from elementary tracks contained in one bundle at a time. The means for displacing comprise a tape guide acting on longitudinal edges of the tape and transversely translating the tape. Furthermore they comprise either a movable tape reels platform or movable pins to accommodate for the transverse tape displacement.

摘要： Magnetic recording and reproducing linear thin film head arrays (30) particularly for use for recording and reading information on a magnetics-on-film (MOF) layer (28) in the image area of photographic filmstrips (10) and particularly a configuration and mounting of such heads to achieve high compliance with the relatively stiff filmstrip and MOF layer in cameras or other filmstrip handling apparatus without damaging the filmstrip. When constrained in the film transport path, the filmstrip assumes a convex cross film curvature on the MOF layer side approximated by a sixth order polynomial having even terms only. A base line for the deposition of thin film head layers of each head of the array on a linear substrate is approximated by the sixth order polynomial having even terms only. After deposition of the thin film layers, the linear head array is shaped to the cross film curvature, and the lapped head surfaces are aligned with the base line. Preferably, at least one electrical lapping guide is deposited on the substrate in relation to the linear array of magnetic head elements and the base line, wherein the head element layer height is controlled in the head fabrication processing by monitoring the electrical resistance of the electrical lapping guide during shaping of the convex curvature of the head surface.
