rumble, on records or from turntable?

I've noticed that, when listening to records using my headphones, I hear a definite rumble at the beginning of the side and in between cuts. Basically only on the parts with little or no volume. It seems that different records have different amounts of rumble. This indicates that it might be something recorded onto the record. My question is, how much of this rumble is coming from the turntable and how much is recorded into the record? Is there a way to check the amount of rumble coming from your turntable?
