摘要

我们描述了在光盘基板上具有圆形边缘的深槽，作为解决注塑困难的一种方法。实际制作并测试了圆边较深的凹槽。有圆边凹槽的冲压件可以很容易地通过修改直接雕刻玻璃母版。复制与母版的可分离性显著提高。无云问题，复制周期短，冲压件寿命长。

High quality optical disc stampers with round edge grooves

We describe a deep groove having round edges in the optical disc substrate as one of solutions for difficulty in injection molding. The round edge deeper grooves were actually made and tested. Stampers with the round edge grooves can be easily made by modified directly engraved glass mastering. Replication separability from the stamper is markedly improved. No cloud problem, shorter cycle time at replication process and longer lifetime of stampers were confirmed.
