That is not an actual slow-motion video of a stylus playing a groove. That was made by stop action photography of static placement of the needle in the groove. It is an animation.

In commemoration of the Grammys.
This photo shows a colorized scanning electron microscope image of a phonograph needle in the groove of a vinyl record. The texture inscribed along the walls of the spiral groove replicates the soundwaves as they were recorded.
