When testing a compact disc, the weight of a compact disc comes into play, especially when testing for the moment of inertia. Thus, the question of "How much does a compact disc weigh?" becomes more important. A typical compact disc weighs somewhere between fifteen to twenty grams, with smaller ones (such as those used for Nintendo Gamecube games, for example) weighing less, perhaps somewhere
. between seven to twelve grams. Their small size does not lend them much in the way of resilience, so taking care of them is important. You can find more information here: http://www.cd-testing.com/#i17
