Abstract
PURPOSE: To secure an assured reading of the information regardless of the distribution direction of the record information by compounding the saw-tooth wave signals of the horizontal and vertical deflection cycles to be applied to the deflecting means of the pickup element and then switching the optical scanning direction in the fixed cycle.
CONSTITUTION: The signals sent from horizontal and vertical saw-tooth wave generator circuits 3 and 4 are applied to adders 21 and 22 for compounding via inverter circuits 5 and 6, gate circuits 7W10, amplitude switching circuits 12W15 plus horizontal and vertical saw-tooth wave voltage amplifier circuits 17/18 and 19/ 20 each. Then the sweep in the horizontal and vertical scanning directions featuring the alternate scanning every field and sent from FF11 is switched via gate circuits 7W10, and furthermore circuits 12W15 are controlled by the shift pulse of shift register circuit 16. And the horizontal and vertical signals are added to adders 21 and 22 with variation of the amplitude, and the signals compounded by adders 21 and 22 are applied to deflecting coils 25 and 26 which deflect the pickup element. Thus an assured reading is secured for the information regardless of the distribution direction of the record information.
