我有一个 733MiB 的 ISO 映像，我试图将其写入 CD-R。我有两张来自不同制造商的 CD-R 光盘。使用第一张 CD-R 光盘（TDK）刻录过程失败，但使用第二张 CD-R（EMTEC）刻录成功。用于刻录的命令是wodim -v speed=1 dev='/dev/scd0' -sao -overburn /home/martin/Downloads/linux.iso
失败的尝试：

超刻能力是否仅取决于 CD-R/CD-RW 引出线尺寸？此外，任何想法“低 Beta 类别 (B-) (4)”和“高 Beta 类别 (A+) (3)”CD-R ATIP 信息部分是什么意思？
答案1
原始CD数据存储大小为650 MiB；这些也称为 74 分钟 CD，因为这是您可以进入同一空间的音频数据量。在 CD-R 开始可用之后，您开始看到 700 MiB（或 80 分钟）的 CD-R。现在销售的大多数 CD-R 都是这种较新的类型。
我从未见过能够容纳 733 MiB 的 CD-R，并且亚马逊“CD-R”搜索结果的第一页没有显示那么大。
也许只是盲目的运气才让这个形象被烧毁。或者，它可能根本没有正确燃烧。如果您的操作系统安装程序具有媒体验证功能，那么您在第一次从过度刻录的光盘安装时绝对应该使用它。
该图像可能根本不适用于 CD-R。 ISO CD 格式最近在 USB 密钥映像中变得流行。有类似的工具UNet启动程序正是为了这个目的。
答案2
Warren Young 在 2013 年可能还不知道这一点，Mediarange 制造的 CD-R 磁盘设计用于接受 90 分钟音乐 (800MB) 或 100 分钟音乐 (900MB)，但您必须在刻录软件中使用特殊的超刻功能。回到过去，Nero 是流行的软件。
现在，在 2019 年，当我安装我的新电脑，寻找同样的旧软件时，当我解释我想如何将音乐刻录到 CD-R 磁盘上并在我的车中使用它们时，我皱起了眉头。人们建议我应该拿出 U 盘，或者通过移动互联网传输音乐。
好吧，我已经尝试过，但是当我中断电源时，即使只是启动引擎，汽车中的 USB 记忆棒也会丢失我正在听的专辑的曲目。移动互联网的费用比我半年在预付费手机上花费的 10 欧元还多。所以，如果你愿意的话，可以叫我老派，但请尊重我的自由选择！ ;-)
