| 摘 要： | 导电式原子力显微镜(Conducting Atomic Force Microscopy:CAFM)和扫描表面电位显微镜(Scanning Surface Potential Microscopy:SSPM)已经被用于相变光盘的信息符成像。在实验中测量了带初始过程的商用DVD-RW光盘。通过比较,CAFM的测量结果明显好于SSPM的测量结果。DVD-RW在3.5m/s的线速度下的恰当刻写功率范围被CAFM确定为10-15mW。这是验证高密度记录符的一个很有效的方法。这种新方法也可以用于新型相变记录材料的研发中。

| Abstract: | Conducting atomic force microscopy(CAFM) and scanning surface potential microscopy (SSPM) have been used to image the phase-change optical recording bits.Commercially available digital versatile discs(DVD) + rewritable(RW) with initialization process were measured in experiments.Comparing the measurement results of both,the measurement resolution of CAFM is far superior to that of SSPM.With the DVD+RW disc rotating at a linear speed of 3.5 m/s,appropriate writing laser power range,may be precisely identifie... |
