Very inadequately. There was a quadrophonic vinyl system that failed commercially, which played back surround speakers using modulation of a 30K carrier tone. You had to use a special (aka 'good') stylus, and it sort of worked. The resulting carrier tones would go from 18 kHz to 45 kHz and the fact that this worked at all is evidence that vinyl goes up that far if you let it: wear will tend to scrub off that information unless it's a high energy transient, in which case there's a big chunk of plastic refusing to be worn off (but you'll dull it).
