[QUOTE="Ampdog, post: 750932, member: 144"] Figures regarding pressure and temperature a mite inflated. The contact area of a stylus tip is a function of the 'compliance' of the record material; it is not as small as I have seen in some calculations, and the mentioned temperature will instantly melt a record. One needs to integrate pressure increments when the stylus follows 'curves' in a groove, something quite variable depending om the recorded music and the static pressure (head downward pressure). The wear does not simply cause a strictly flat surface although a powerful microscope is required to see that. Nonetheless, the wear-picture was well-stated. Also remember that the stylii are mostly industrial diamonds. They last some 4x longer than sapphire if my memory serves, again depending. [/QUOTE]
