The ISO file format is pretty much entranched in the PC world as THE format to use for CD/DVD disk images. The advantages of this format are plenty – It is a standard open format and tools to work with it are readily available for all operating systems, Windows, Unix/Linux and OS X.

You can now use Nero, cdrecord/wodim or the OS’s built in ISO burning tools to burn this ISO file to any media.
