A METHOD AND DEVICE FOR RECORDING INFORMATION SIGNALS ON A PARTLY RECORDED WRITABLE RECORD CARRIER (11), E.G. AN OPTICAL DISC.AN INFORMATION SIGNAL REPRESENTS AT LEAST ONE INFORMATION UNIT. THE RECORD CARRIER HAS A RECORDING TRACK WHICH COMPRISES PREFORMD TRACK POSITION INFORMATION INDICATIVE OF LOCATIONS FOR RECORDING THE INFORMATION UNITS. FROM THE INFORMATION SIGNAL A MODULATED SIGNAL IS GENERATED HAVING SUCCESSIVE FRAMES, EACH FRAME INCLUDING A SYNCHRONIZING SIGNAL. THE MODULATED SIGNAL IS RECORDED AT A ONE OF SAID LOCATIONS, WHILE MAINTAINING A FIXED RELATIONSHIP BETWEEN THE TRACK POSITION INFORMATION AND THE SYNCHRONIZING SIGNALS. IN THE EVENT THE LOCATION IS AFTER AND ADJACENT TO AN ALREADY RECORDED LOCATION, THE RECORDING IS STARTED AT A LINK POSITION (31) BEFORE THE END OF A LAST FRAME OF THE EARLIER RECORDED INFORMATION SIGNAL AT A PREDENFINED DISTANCE BEFORE A FIRST SYNCHRONIZING SIGNAL (30) OF THE MODULATED SIGNAL.(FIG. 3)
