    Abstract: Embodiments of the present invention provide a coding system that codes data according to a pair of coding chains. A first coding chain generates coded video data that can be decoded by itself to represent a source video sequence of a small size, such as a size sufficient to support the real time playback and display features of a video editing application. The second coding chain generates coded video data representing supplementary data, which when decoded in conjunction with the coded video data of the first coding chain, yields the source video sequence for full-size display. The output of the first coding chain may be stored in memory in a file structure that can be accessed independently of the second chain's output and, therefore, it facilitates real time decoding and playback.

    Abstract: The general concept of the invention is to coat, at least, the trailing pole face of a pair of ferrite pole faces (26), which define a transducer gap, with high-saturation material (30) such as Sendust. By so structuring a head with a gap liner, not only is the critical part of its gap defined by material having a high saturation magnetization -- and thus such head will no be easily subject to critical pole tip saturation of its trailing pole face -- but also (1) the long-wearing ferrite will desirably constitute the principal head part that slidingly coacts with a recording medium, (2) no high reluctance glue line will exist between a core and its tips, and (3) the signal flux will enter the gap region uniformly over the surface of the gap, thereby providing enhanced high frequency efficiency.

    Abstract: A magnetic head device retrieves information signals from recording media, such as magnetic tape, which records information signals in tracks adjacent to one another. Magnetic core halves are opposed and joined in such a positional relation that cross talk noises read from adjacent tracks are reduced. The core halves are easily joined, thus facilitating the manufacture of recording heads.

    Abstract: The formation of a gap in a magnetic head core or the junction of a thin magnetic film of a metal with an oxide substrate of a magnetic head made of a composite of a thin magnetic film of a metal with an oxide material are conducted by the thermal diffusion between golden layers themselves at a low temperature. Then, chromium or titanium is made present between the gold layer and the junction surface to prevent deterioration of magnetic characteristics and generation of false gap and, at the same time, to heighten the junction strength. The thermal diffusion between golden layers themselves is effected at a temperature lower than that of glass fusion to suppress the deterioration of magnetic characteristics, distortion caused by the thermal expansion, and diffusion reaction on the interface. The chromium or titanium layer works to maintain junction strength between the thin magnetic layer or the oxide substrate and the golden layer.
