One of the benefits of the advanced shapes is to increase the contact radius. In theory the worst shape (the spherical) contacts the vinyl wall at an infinitesimal dot. So the contact area is (in theory), ZERO. But, of course, vinyl deformates, so a practical contact area will be established, and it will have to be estimated for the spherical. Seems Namiki did an estimation of the contact areas. Note that "Line contact" here is actually the Shibata. Another comparison of contact surfaces plus dimension data, this time from Audio Technica. Here for example you can see why a line contact shape is beneficial: The best high frequency readout will be obtained with a 0.2mil side radius (or smaller!).
Note that the last row (L1/L2 or "F") tells you how "tall" is the side contact, the taller the better since it means big contact area but with small side radius. Also note something more interesting. Now, a footprint comparison from the JICO SAS flyer. Micrographia: Applications: The microscopy of vinyl records. Page 3. Audiokarma Home Audio Stereo Discussion Forums. The Cartridge Mount Each potential microscope user could have one of several different cartridge examination possibilities.

Cleaning vinyl records and keeping them dust free is a major factor in preserving them and keeping their perfect sound quality for longer.
The crackling noise and pops that you experience with many of the records is the result of dust settled and accumulated in the grooves of the vinyl over a long period of time. Also, the friction and heat created by the stylus hitting dust particles as it rides between the grooves, create some kind of mini explosion that can blast holes in the grove walls of the record.
Even new records come coated in some sort of mold release compound that should be cleaned off before the first play to bring out the best quality of sound from your vinyl. It has been shown that playing dirty records can cause permanent damage, not only to the vinyl itself but also to your stylus.
