CD-ROM的标准有两个层次,分别的定CD-ROM盘的物理和逻辑格式。 有关物理格式标准含在高密度激光盘 (CD,即COMPACT DISC)的标准中,其作用是保证高度激光盘可在不同厂家生产的驱动器中使用。这方面的标准共有三个: 红皮书,规定了音响光盘(CD-DA)的物理规格。规定光盘外径为120毫? The standard CD-ROM has two levels, respectively, set the physical and logical format CD-ROM disk. The relevant physical format standard is included in the standard for high-density laser discs (COMPACT DISC), which ensures that a high-density laser disc can be used in drives manufactured by different manufacturers. There are three standards in this area: the Red Book, which defines the physical specifications for compact discs (CD-DA). Disc diameter requirements of 120 milliliters
