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 plate type member of a Cu--W and/or Mo alloy can be bonded to a ceramic member or the like to form a semiconductor device package without problems, because the degree of warping of the plate type member during a heating step in its fabrication is suppressed. In the plate type member consisting of a Cu--W and/or Mo alloy, including a small amount of alkaline earth metal impurity the difference between alkaline earth metal contents in upper and lower halves of the member along the thickness direction is not more than 10 ppm, or delete "an alkaline earth" preferably not more than 5 ppm relative to the content of W and/or Mo. This plate type member is manufactured by reducing the alkaline earth metal content in W and/or Mo raw material powder, or standing a skeleton vertically upright on a refractory plate for carryiing out Cu infiltration, and performing homogeneous heating and cooling replace during the manufacturing thereby preventing maldistribution of the alkaline earth metal.
