    • 专利摘要:
    A system for recording signals in a disc master comprises an electromechanical cutterhead responsive to the signals and a signal processing means interposed between the cutterhead and a signal source. The signals applied to the cutterhead are of the encoded type such that most of the signal energy is contained in signal components occupying a band of frequencies about one octave wide or less. The cutterhead is so constructed that its response to the signal components varies with frequency in substantial correspondence with the energy distribution of the maximum signal components over the afore-mentioned band. The signal processing means serves dual purposes. On the one hand, it cooperates with the cutterhead to provide a combined frequency response which is relatively uniform. On the other hand, it serves to reduce the energy level of high energy level signal components applied to the cutterhead. The reduction of the applied energy makes possible the use of a smaller cutterhead than would otherwise be the case. The smaller cutterhead structure, in turn, results in a relatively wide cutterhead bandwidth.

    专利说明:

    The invention relates to television, in particular to recording a television signal on a storage medium. The aim of the invention is to expand the television signal bandwidth. The drawing shows an electrical block diagram of a device for electromechanical recording of a television signal, a device for electromechanical recording of a television signal contains a video signal generator 1, a sound signal generator 2, a video signal frequency modulator 3, a sound signal frequency modulator A, a power amplifier 6 matching transformer 7, a recorder (not shown), a video signal frequency converter 8, a signal converter sByKOBofo frequency converter 9, a correction unit 10, as well as a base, pied zoelectric element and cutter (not shown). Device for electromechanical. The recording of the television signal works as follows. The video signal from the imager 1 video signal and the audio signal from the generator 2 audio signal input UT, respectively, to the video signal frequency converter 8 and to the audio signal frequency converter 9, the output of each of which is respectively through the video frequency modulator 3 video signal and the frequency modulator A sound the signal is connected respectively to the first and second inputs of the adder 5, from the output of which the signal goes to the correction unit 10, the function of which is to selectively reduce the energy levels of the computer onent signal. The signal from the correction unit 10 is fed to the recorder through the power amplifier 6 connected in series and the matching transformer 7, the Recorder responds to a relatively high-frequency signal. If the signal is recorded in real time, the video signal frequency converter 8 and the audio signal frequency converter 9 are excluded. The recorder contains a piezoelectric element inserted between the cutter and the base. A device for electromechanical recording of a television signal allows the frequency band of a recorded television signal to be expanded.
