Abstract: When a medium casing is properly inserted, a first pair of projections and a second pair of projections are passed through between a first bottom surface and a second bottom surface of a chassis in the moving direction and are thus prevented from coming into contact with the first and second bottom surfaces, thereby allowing for smooth insertion of the medium casing. In contrast, when the medium casing is inserted improperly from its wrong end, one of the projections on the lower surface of the medium casing comes into abutment with the second bottom surface of the chassis near the opening. Accordingly, an improperly inserted medium casing can be prevented from being inserted any further at an early stage of the insertion process.

Abstract: A magnetic servo write head incorporates timing pattern read and write heads that are non-symmetrically slanted relative to an adjacent servo write head to improve timing pattern detection for a timing pattern written at an edge of a magnetic storage media. The slanted orientation of the timing write and read heads provides optimized timing pattern location and track width on a magnetic tape, while also allowing a sufficient number of windings to be used on an associated coil to improve overall signal-to-noise ratio.

Abstract: A thermal processor and method for using the same which is particularly useful for developing a sheet of imaging material, such as photothermographic film. The thermal processor includes means for transporting the imaging material through the apparatus. The thermal processor also includes means for heating the imaging material to develop the image in the imaging material. The thermal processor also includes means for reducing fogging on the imaging material as the image is developed on the imaging material.

Abstract: The present invention relates to a method for manufacturing a silver halide photographic emulsion comprising a nucleation step, a growing step and a washing step, wherein a reduction sensitization is performed between said growing step and said washing step in the presence of a sulfuring agent and a stabilizer. According to a preferred embodiment a fine grain silver halide emulsion is added either between the addition of stabilizer and the addition of sulfuring agent or between the addition of sulfuring agent and the start of reduction sensitization or both.
