  • Thermomagnetic writing of pulse sequences of controlled magnitude and variably controlled duration
    Patent number: 6646970
    Abstract: A device according to the invention for writing information to an information carrier (1) includes conversion means (7) for converting symbols in an information signal (SINFO) into pulse sequences in a control signal (STR). The device further includes a transducer (10) for generating a physically detectable pattern on the information carrier (1) in response to the control signal (STR). The conversion means (7) include assignment means (702) for assigning properties of the pulse sequences to symbols in the information signal (SINFO). These properties include the duration and the magnitude of pulses in the pulse sequence. The conversion means (7) further include at least one counter (711) for supplying a count signal (TC1) after a time interval, which counter is coupled to the assignment means (702). The conversion means (7) further include a controllable delay line (761) coupled to the at least one counter (711), for delaying the count signal (TC1), and to the assignment means (702).
