脉冲冷却BD基片注塑成型的优化之径

Pulsed Cooling——optimising BD substrates moulding

一、引言 对蓝光只读光盘(简称BD-ROM,后同)和蓝 光可重写光盘(简称BD-RE,即BD-RE-Writable,后 同)基片注塑成型工艺的研究涵盖了一系列的实验工 作,通过这些研究,人们希望能够找到蓝光光盘(简 称BD,后同)基片的最佳注塑成型工艺,或者优化方 法。在这些和工艺相关的实验研究中。

Investigating the substrate moulding process for BD-ROM and BD-RE (re-writable) substrates moulding process, involved a series of experiments investigating and optimizing the moulding process for BD substrates. The investigation showed that, compared to the stationary type of cooling, the Pulsed Cooling method of moulding the BD discs, manufactured substrates with lower birefringence, tilt, dishing, very good groove/pit replication quality with shorter cycle time and using the lower mould temperature.
