MM or MC......Voyager Expedition


Watched a very interesting program on PBS the other day about the Voyager Expedition.  A lot of time was devoted to the gold record that accompanied the space craft on its journey.  The Chief Engineer mentioned that a cartridge was included along with the record and with graphic instructions on how to play the recording.  No mention by the engineer if MM or MC cartridge was chosen.  Does anyone have any inside information on what type of cart was included?  Just curious.....Thanks!

Apparently it was neither:

Ceramic cartridges are an old relatively lo fi technology based on piezoelectric effects, rather than electromagnetic principles. They typically provide much higher output voltages than MM or MCs, and I believe they can perform more reliably than MM or MCs in the presence of severe vibration.
