    摘要: Apparatus for recording an information signal on a metallic record carrier. The information is impressed on the carrier by cutting a groove therein by means of a stylus, the groove being characterized at each point by a slope or modulation pitch angle. The stylus has a longitudinal axis, a leading edge substantially parallel to this axis and a trailing edge. The angle between the longitudinal axis of the stylus and a normal to the surface of the record carrier is greater than 10.degree. and not more than a value which would make the angle between the trailing edge of the stylus and the surface of the record carrier less than the maximum modulation pitch angle. The stylus is movably attached to a fixed structure by a mounting member and is electromagnetically excited by a driving member to shape the grooves in the record carrier in accordance with the information signal. The record carrier, stylus, mounting and driving members are dimensioned to generate an oscillation at a frequency which is higher than that of the information signal and superimpose this oscillation on the information signal.

    摘要: A method of forming a disc having an information recording groove of regular cross-sectional shape by forming a preliminary spiral groove of trapezoidal cross-section in a disc having a relatively flat surface, and then flowing an excess of viscous material on the groove surface of the disc while rotating the disc rapidly and long enough to flow off the excess viscous material so as to leave a continuous coating of viscous material over the surface of the disc, the trapezoidal regions being covered by a coating having a relatively constant radius of curvature.

    摘要: A flatbed cutter assembly includes a medium support table for supporting a recording medium, the table extending in a first direction and a second direction, the first direction being perpendicular to the second direction, a gantry arranged to be moveable over the medium support table in the first direction, a carriage support movably arranged on the gantry to move over the medium support table in the second direction, a cutter configured to be coupled to the carriage support and a controller for controlling the movements of the gantry, the carriage support and the cutter while moving over the medium support table. The controller is configured to cut through the recording medium from the front side to the back side along a cut path except for a plurality of bridges along the cut path, the recording medium intended to be printed on both front and back side of the recording medium, wherein parts of each bridge which are intended to be adjacent to printed images on the front and back side of the recording medium, are removed by the cutter.

    摘要: A record engraving apparatus having a table with a vacuum source for retaining thereon a master lacquer with portions thereon having pre-recorded disc-shaped record portions. The rotatable table is precisely positionable in all directions of the plane of the table as well as in orthogonal directions, and includes provision for mounting the master lacquer with the center thereof in one of at least two locations depending on the center of the record portions relative to the master lacquer. A vertically adjustable arm is provided with a turret head having thereon a plurality of heated sapphire cutters of different sizes, each of which may be indexed into position. The arm is adjustable in a direction orthogonal to the plane of the table to provide variations in depths of cuts.

    摘要: A method for cutting a modulated groove into the surface of a gramophone record disc. The groove is cut by a cutting stylus the tip of which is guided relative to a constant depth cutting plane located well below the lowest point of wobble and/or irregularity of the original disc surface. Thus, the parts of the groove crest formed when walls of adjacent grooves intersect during cutting of the disc are substantially below said lowest point of the original disc surface.
