They still do, although these days the "landing zone" has a special surface designed to minimize friction on the head and prevent it from sticking to the surface. In addition, in an emergency unload (when power is lost while the disk is still spinning) the heads retract in a violent and uncontrolled manner, which can lead to mechanical damage to the arms.
