Voyager I and II: Golden Record Mechanics


Hello: Would someone please assist us with some information on the Gold/Copper composite record that was launched on the Voyager I and II missions in 1977. Specifically, does anyone out there know who manufactured the stylus that NASA included with the record; what kind of stylus would be able to track such a Gold/Copper composition -- e.g. a standard nude elliptical stylus -- and moreover withstand the merciless elements that now accompany Voyager I and II as they reach and speed past the "terminal shock" zone at a distance of more than 9.4 billion miles and 7.4 billion miles from earth respectively.

Thank you for your time and patience researching this matter.

If you need some general info. on the Gold Record, please see "http://voyager.jpl.nasa.gov/spacecraft/goldenrec.html." If you're curious, as I was last night upon encountering this phenomena of science, please see http://goldenrecord.org/ for the music and photographs chosen for the Golden Record.

Pardon: Corrections are Voyage I and II are more than 9.4 billion miles and 7.4 billion miles from the Sun; "terminal shock" should be "termination shock."
