        "note": "Unrolled, the spiral groove is astonishingly long: its length ≈ the number of turns × the mean circumference (π × the average of the outer and inner diameters). A 12-inch LP side runs on the order of 400–500 metres of groove. The stylus traces this whole length once per side, which is why a tiny mistracking error repeated over half a kilometre of wall undulations is audible.",
