1 引言光盘检测是光盘质量控制中的重要环节,是产品分级,市场准入的重要判别手段。光盘检测包括在线检测和离线检测,在线检测是光盘生产过程中不可或缺的重要环节,伴随着光盘生产的每个工艺步骤;离线检测是光盘工艺调整、光盘质量评判的重要手段。光盘检测仪按其使用方式可分为在线检测仪和离线检测仪,按其检测参数可分为电信号检测仪和光学信号检测仪。电信号检测仪通常为离线检测仪,主要检测完成盘的播放性能,通常以国际工业标准(例如CD-Audio的红皮书)为依据,电信号检测仪也包括Master检测仪,Stamper检测仪,以及ECC校验等检测仪。本文所指电信号检测仪具有普遍意义,仅指完成盘的电信号检测
1 Introduction CD-ROM testing is an important part of CD-ROM quality control, product classification, an important means of market access. Optical disc testing includes on-line testing and off-line testing. On-line testing is an indispensable part in the optical disc manufacturing process, accompanying each process step of disc production. Offline testing is an important means for disc process adjustment and disc quality evaluation. CD-ROM detector according to their use can be divided into online detector and offline detector, according to their testing parameters can be divided into electrical signal detector and optical signal detector. The electrical signal detector is usually an offline detector, which mainly detects the playing performance of the completed disk. The electrical signal detector usually is based on international industrial standards (such as the CD-Audio’s redbook). The electrical signal detector also includes a Master detector, a Stamper detector, and an ECC Calibration tester. This article refers to the electrical signal detector has a universal significance, only refers to the completion of the disk electrical signal detection
