摘要： It is desired that the overshooting and undershooting of optical pulse waveforms of optical pickups included in optical disk devices be reduced to improve the quality of recording. Among pulses to be recorded, the trailing edge of each last pulse and the leading edge of the subsequent erase top pulse are made to almost coincide with each other. Ratio a/b, where a is the difference between erase top pulse power level Pet and erasing power level Pe and b is the difference between recording power level Pw and the erasing power level Pe, is adjusted to realize an optical pulse waveform with reduced overshooting and undershooting for each of different recording media. Erase top pulse duration Tert is switched according to different recording speeds for different recording media.

摘要： A high voltage variable resistor section (8) for deriving the focusing voltage and screen is attached to an open portion formed on one surface of a first case (47) which receives primary and secondary windings (2, 3) included in a flyback transformer section (1). An insulating substrate (16) on which resistor elements (9-13) included in the high voltage variable resistor section are formed in housed in a second case (15). An opening is formed in one surface of the second insulating cases (15). With this opening communicating with the opening in the first insulating case, the two insulating cases are integrated. These insulating case define insulating case means, in which a high voltage capacitor (14) for compensating cathode ray tube capacity is housed. The high voltage capacitor is disposed between the secondary winding (3) and the resistor elements (9-13) in such a manner that the surfaces of the electrodes (38, 39) of the high voltage capacitor are opposed to the secondary winding (3) and the resistor elements (9-13). This arrangement prevents unnecessary radiation components due to ringing noise induced in the secondary winding from being transferred to the resistor elements and superposed on the focusing voltage.
