声光调制器在光盘记录中的应用

Applications of the Acoustooptic Modulator in Optical Disk Recording

本文简要比较了用外调制的气体激光器与用内调制的半导体激光器在光盘技术中的特点,详细介绍了声光调制器在多通道数字光盘记录器,光盘伺服槽刻划机和光盘材料测试仪中的应用。

This paper briefly compared ihe characters about the gas laser with extra modulation ar.d the semiconductor laser with inner modulation in optical disk technology. The applications of acoustooptic modulators in multichannel digital optical disk recorder, grooving machine and optical disk media tester are described in detail.
