A New Process for Manufacturing Optical Disks

9500162比法诺这项研究将调查光学编码信息盘(例如：光盘或CD)的新制造工艺。目前的制造技术将发生两大变化：(1)用坚韧的陶瓷取代玻璃母盘基板，用作注塑模具冲压件；(2)用单一离子加工步骤取代电镀、剥离、保护、抛光和冲孔操作。最重要和最具技术挑战性的步骤是将CD信息记录在母盘上的离子加工过程。这项技术将是通过掩模进行宽束离子加工，在单一基板上产生数十亿种均匀优质的特征。如果这种新的精密制造策略能够被证明适用于CDS，它就有可能完成对其他微机械加工技术的研究。这项研究有可能将制造过程时间缩短一半，同时降低制造成本和在制品库存。此外，通过消除电镀和其他需要严格环境控制的步骤，离子束加工可以为环境友好的制造过程提供替代选择。随着信息技术的蓬勃发展，CD的海量存储能力，这种制造工艺有望继续推动信息传播的成本。

9500162 Bifano The research will investigate a new manufacturing process for optically encoded information disks (eg: compact disks or CDs). Two major changes in the current manufacturing techniques will be undertaken; namely, (1) replacement of the glass master disk substrate by a tough ceramic, which will be used as the injection mold stamper, and (2) replacement of electroplating, peeling, protecting, polishing, and punching operations by a single ion machining step. The most important and technically challenging step is the ion machining process for recording CD information on the master disk. The technique will be broad beam ion machining though a mask to produce billions of features with uniform good quality on a single substrate. If this novel precision manufacturing strategy can be proven for CDs, it carries the potential to complete against other micromachining techniques. This research has the potential to cut manufacturing process time by half reducing both manufacturing cost and work in process inventory. Further, by eliminating electroplating and other steps requiring stringent environmental controls, ion beam machining can provide the alternate choice for an environmentally benign manufacturing process. With the boom of information technology, mass storage capabilities in CDs, this manufacturing process holds the promise for continually driving the cost of information dissemination.
