Synthesis of New High Sensitivity Phase Change Erasable Optical Data Storage Materials

使用基于复杂图形和图像的信息的计算系统需要存储和检索非常大的数据文件。光盘系统提供了任何随机存取存储系统中最大的存储容量，但由于它们的高成本，没有得到广泛的使用，特别是在PC市场中。这些驱动器中的一个主要成本项目是它们所需的高功率激光二极管。通过开发更灵敏的光学记录介质，从而可以使用更低功率、更便宜的激光二极管，可以显著降低这一成本。我们计划应用我们在相变材料研究过程中开发的材料和器件设计理念来开发适用于低功率、低成本激光二极管的可擦除光记录介质。这些材料在两种结构相中都将具有快速结晶动力学和稳定性。这种新的相变可擦除媒体将在商业和技术计算以及互动教育和娱乐系统中有潜在的应用。这项卓越的技术提供了一个极好的机会，可以在公认为未来十年主要增长的市场上展开竞争。

Computing systems that use complex graphic and image based information require the storage and retrieval of very large data files. Optical disk systems offer the largest storage capacity of any random access storage system, but widespread use, especially in the PC market, has not occurred because of their high cost. A major cost item in these drives is the high power laser diode they require. This cost can be dramatically reduced by developing more sensitive optical recording media so that lower power, less expensive laser diodes can be used. We plan to apply materials and device design concepts we have developed in the course of our study of phase change materials to develop erasable optical recording media suitable for use with lower power, less expensive laser diodes. These materials will have rapid crystallization kinetics and stability in both structural phases. This new phase change erasable media will have potential application in business and technical computing, as well as interactive education and entertainment systems. This superior technology provides an excellent opportunity to compete in markets recognized for major growth over the next decade.
