Oh, I'm sure the recorder as such is severely damaged after such a high-speed impact. The only thing that is really protected is the recording medium. I'm confident that will be fine, or at least readable with specialised equipment. These containers are made to withstand just such a crash, and since they're in the tail, they effectively use the entire aircraft as a crumple zone.
