My cd-rom drive keeps on opnening and closing?can

Dude CD ROM's are designed to close all by themselves in case if there is anything stuck in between,just unplug the CD Rom,and u might find a small hole,kindly punch in it using a pin so that the front portion of cd rom will open and clean up the entire drive using a soft brush(b careful about lens present inside)and fix it back and check out whether it works out
