  • Method of writing information with a modulated radiation beam onto an information storage medium and information storage medium particularly adapted to the method
    Patent number: 4038663
    Abstract: A method and apparatus for writing video information with a laser on a recording surface employing a protective foil on the writing surface through which foil the laser write beam is focussed. A stream of filtered gas is passed between the foil and the writing surface to remove any gaseous or particulate by-products of the writing process, and to protect the writing surface from room contaminance.

  • Drop out compensation device
    Patent number: 4032966
    Abstract: A device for compensating dropouts in color television signal modulated by a carrier wave. The modulated video signal is applied to a first delay line, from whose output signal a luminance component delayed by one line period is derived with the aid of a demodulator, and is also applied through a second demodulator and a chrome separating filter to a second one line delay line. The sum of the delayed chrominance and luminance components are substitution for the demodulated color television signal during a dropout.

  • Device for the compensation of drop-outs in a angle-velocity modulated signal
    Patent number: 4000511
    Abstract: A device for the compensation of dropouts in an angle modulated signal. The device comprises a variable delay line, which receives a control signal from a control unit for variably delaying said angle-modulated signal. The control unit comprises a dropout detector and a transformation means co-operating therewith for supplying an output signal which is representative of the magnitude and the polarity of the dropout. Said output signal is applied to the variably delay means as a control signal.
