Abstract: Playback transducers for patterned media systems comprise temperature sensitive resistors, including thermistors and resistance temperature detectors. The transducers are typically thin film depositions mounted on a slider for flying head application. Possible configurations are generally V-shaped, may involve parallel or perpendicular recording geometry, and are conceptually similar to (but simpler in construction than) magnetoresistive or giantmagnetoresistive thin film transducers. The transducers may incorporate supplementary heating elements and/or coatings to optimize performance.

Abstract: The present invention relates to a photographic film base comprising a transparent support base and a binderless layer of magnetic material coated thereon.According to another aspect, the present invention relates to a color photographic material comprising a photographic film base and at least one light-sensitive layer coated thereon, wherein said photographic film base comprises a transparent support base and a binderless layer of magnetic material coated thereon.

Abstract: A housing apparatus is operable to align a record/playback head with respect to different parallel tracks on a moving magnetic tape in such a manner as not to disturb the positioning of the tape as it passes longitudinally along its transport path. The housing apparatus includes a housing body having a convex, rounded front face lying in contacting relation with respect to the moving magnetic tape at two closely spaced-apart areas. A record/playback head is transversely movable with respect to the housing body and extends through a provided opening in the body to lie in contact with the moving tape between the two tape contacting areas of the housing body front face. Means is provided to move the record/playback head transversely with respect to the tape while the moving tape is in contact with these two areas on either side of the head.

Abstract: A support yoke for a video recording core having a narrow body portion and two wire-wound coils includes a narrow slot for supporting the body portion of the recording core between the coils and relief pockets formed on either side of the narrow slot to accommodate the wire-wound coils.
