标准范围

ISO/IEC 17592:2004规定了光盘的机械、物理和光学特性,即DVD可重写光盘(DVD-RAM),以实现此类光盘的交换。它规定了记录信号的质量、数据格式和记录方法,从而允许通过这种磁盘进行信息交换。使用相变方法可以多次写入、读取和重写数据。指定了两种类型,它们的不同之处仅在于直径为120 mm和80 mm,以及由此产生的容量差异。

ISO/IEC 17592:2004 specifies the mechanical, physical and optical characteristics of an optical disk, identified as DVD Rewritable Disk (DVD-RAM), to enable interchange of such disks. It specifies the quality of the recorded signals, the format of the data and the recording method, thereby allowing for information interchange by means of such disks. The data can be written, read and overwritten many times using the phase change method. Two Types are specified that differ only by their diameter of 120 mm and 80 mm, and the resulting difference of capacity.
