摘要
采用波长为405nm的蓝光半导体激光器和数值孔径为0.65的聚焦物镜,对不同激光功率下CD-RW相变材料的存储特性进行研究.结果表明,在本系统中,CD-RW相变材料记录阈值约为7.5mW,最佳记录功率为9.0mW,最终得到了约500nm的记录线宽.
This paper studies the characteristics of optical recording of CD-RW with 405nm laser source and 0.65 numerical aperture (NA) objective lens. The result reveals that the threshold and optimal laser power in this recording system is 7.5mW, 9mW respectively. A track with a width of 500nm is obtained on the CD-RW disk.
