Clone: Copy the "disk image". For an audio CD, this also includes the subchannel information, eg CD-TEXT and stuff. It also preserves inter-track gap sizes[1] and any intra-track seek markers which may be defined.
I believe that is how CD game manufacturers make it hard to copy their CDs by putting that weird intertrack stuff and then looking for them before running.
Cloning is how to (supposedly) get around it (usually illegally).
