摘 要

在可记录数字信息媒体领域中，可记录光盘以其数据存储密度高、容量大；存储寿命长、功能多样、使用方便；制造成本低廉等特点成为今天信息社会中不可或缺的信息记录载体。本文通过研究可记录数字通用光盘DVD-R盘片生产注薂@尚凸ひ展讨械母鞑问肱唐柿恐涞墓叵担词迪諨VD-R生产过程中的质量控制。
DVD-R的生产工艺复杂，在生产中的各个环节品质检测和控制手段有着严格的要求。整个生产过程中产生缺陷不可见，只能通过检测仪器来测量其质量，衡量其各项指标是否合格。DVD-R光盘主要是由两片厚为0.6mm的盘片粘合而成，其中光盘基片的精密注塑是光盘复制工艺过程的关键技术，在这一精密注塑过程中要将微小的凹槽精密地复制出来。符合光盘品质要求的主要指标：低双折射、良好的沟槽复制和盘片平整性。

ABSTRACT

In the field of digital information can be recorded discs，DVD-R with high-density data storage，large capacity，long storage life，versatile，usage convenience，manufacture low-cost and other characteristics has became an integral part of the record information carrier in the information society. Based on the research of the relationship between the DVD-R production injection molding processes in the various parameters and the quality of the DVD-R disc, the production process of quality control will be achieved.
With the complex production process of DVD-R, all the aspects of the production of quality testing and control methods have stringent requirements. DVD-R discs was consisted of two 0.6mm thick discs, and the injection process is the one of the important technologies of the whole copy production process. In this injection process, the precision groove will be copy with quality requirements of the DVD-R key indicators: low birefringence, a good groove and a neat disc.
In this paper, through the appropriate changes in injection molding process parameters, such as the mold temperature, the charging temperature, injection of speed, clamping force and other process parameters to study the specific impact in quality indicators such as DVD-R disc thickness, the shape of groove, birefringence and the tile. With the conclusion of this research, the optimal process parameters for production can be easily found, and the control in the production quality can be carry out.


Key words： DVD-R，Injection moulding，Technological parameter，Quality controlled
