Hey Nigel,
I'm not a lawyer, by the way (even if I'm in court rooms all the time).

"Ripping" means exactly that. I know that I shouldn't use Wikipedia as a reference, but I am a professor of computer science and I agree with the definition there:
Ripping is the process of copying audio or video content to a hard disk, typically from removable media such as compact disc (CD) or DVD, although the word refers to all forms of media. Despite the name, neither the media nor the data is damaged after extraction. Ripping is often used to shift formats, and to edit, duplicate or back up media content.
