Where does OS X store the list of disabled fonts? I am using Font Book a lot and manage my fonts with it. Now, I want to back up all my settings.

I found my collections in ~/Library/Font Collections

But where does OS X store which fonts are disabled? I want to copy this "list" and move it to my new mac.
I don't have Fonts Disabled folders either, but the list of disabled fonts is stored in ~/Library/Preferences/com.apple.FontRegistry.user.plist. If you copy it to another computer, run sudo atsutil databases -remove; atsutil server -shutdown to apply the changes.
