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.

使用基于复杂图形和图像信息的计算系统需要存储和检索非常大的数据文件。光盘系统是随机存取存储系统中存储容量最大的系统，但由于其成本高，没有得到广泛应用，特别是在PC市场。一个主要的成本项目在这些驱动器是高功率激光二极管，他们需要。通过开发更灵敏的光学记录介质，从而使用更低功率、更便宜的激光二极管，可以大大降低成本。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概念来开发可擦除的光学记录介质，适用于更低功率，更便宜的激光二极管。这些材料在两种结构相中都具有快速的结晶动力学和稳定性。这种新的可擦除介质将在商业和技术计算以及交互式教育和娱乐系统中具有潜在的应用。这种卓越的技术为在未来十年公认的主要增长市场中竞争提供了绝佳的机会。
