摘要： An arrangement for the recording of a digital information signal, in particular onto a plate-shaped, metallic recording carrier with the aid of a penetrating element is specified, in which the latter preferably has a pyramid shape with three side surfaces and three edges. The edge (6) forming the runner of the penetrating element lies, in its projection onto the recording carrier, in the direction of the velocity vector at the point of recording. The edge forms with the velocity vector an angle of >135.degree.. The projections of the two further edges onto the recording carrier lie perpendicular to the velocity vector. With the aid of such a penetrating element, an engraving of a digital signal is possible, which is read out by a laser beam.

摘要： A method for producing a prerecorded disk-shaped die is specified in which the information signal is recorded onto a metallic recording medium. According to the invention, the information carrier layer consisting of base metal is first vapor-deposited onto a glass base. Then the information signal is recorded onto the surface of the information layer with the aid of a cutting or stamping tool. Following this, a metallic interlayer of precious metal is galvanized on, onto which another base layer particularly of metal, is then galvanized. After the glass base has been mechanically separated, the information carrier layer can then simply be removed by a chemical medium which does not attack the interlayer. The method according to the invention is particularly suitable for producing dies for digital sound recording according to the compact disk process.

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 and apparatus for reducing a resonance peak in a piezoelectric transducer for mechanically recording a signal having a band width of several MHz, in particular on a video disk comprising, applying a countercoupling current across terminals of the transducer for counteracting a current flow in the parallel capacitance of the transducer. A circuit of the invention comprises a piezoelectric transducer having two terminals and including in series a characteristic inductance, capacitance, and resistance, and a parallel capacitance characteristic in parallel to the series characteristic, a signal generator for generating the signal to be recorded, a transformer having a primary winding connected to the signal generator and a secondary winding connected to one terminal of the transducer with a symmetrically disposed central ground connected to the secondary winding. An opposite end of the secondary winding and the other terminal of the transducer are connected to a loading resistor and in turn connected to ground. A compensating capacitor is connected between the other end of the secondary winding and the loading resistor for compensating current flowing through the characteristic parallel capacitance of the transducer. A countercoupling line is connected between the loading resistor and one input of the signal generator so that the countercoupling current may be applied to the signal so as to reduce the resonance peak in the piezoelectric transducer.
