1 引言本文所述 DVD 光盘仅指 DVD 只读盘:DVD-Audio,DVD-Video,DVD-ROM。本文所述内容遵循 DVD Fo-rum 规范。DVD 在问世之初是数字视频盘(Digital VideoDisc)的简称,但由于应用的多样化,它已演变成数字多用途盘(Digital Versatile Disc)。与 CD 光盘测试参数类似,DVD 光盘测试参数可分为:机械参数,伺服参数,高频幅值参数,高频脉宽参数,误码参数,高速参数,光学信号参数。DVD-ROM 类光盘内容表信息:Book 类型,Part 版本,盘片尺寸,最小导出速率,层号,跟踪道径类型,层类型(DVD5或 DVD9),线密度,道密度,起始扇区,结
1 Introduction DVD discs described herein refer only to DVD-only discs: DVD-Audio, DVD-Video, DVD-ROM. The content described in this article follows the DVD Fo-rum specification. At the beginning of its birth, DVD was short for Digital Video Disc, but has evolved into a Digital Versatile Disc due to the diversity of applications. Similar to the CD disc test parameters, the test parameters of the DVD disc can be divided into mechanical parameter, servo parameter, high frequency amplitude parameter, high frequency pulse width parameter, error code parameter, high speed parameter and optical signal parameter. DVD-ROM Disc Contents Table Information: Book Type, Part Version, Disc Size, Minimum Export Rate, Layer Number, Tracking Path Type, Layer Type (DVD5 or DVD9), Line Density, Road Density, Start Sector, Knot
