Part of a hard disk drive. The actuator is a motor that moves the read and write heads in very tiny and precise increments. While stepper motors were utilized for this purpose in the past, modern drives require much more precise movements than a stepper motor can perform, so a voice coil is utilized instead. The actuator arm connects the disk heads to the actuator motor and is designed much like a comb, with two arms for each disk platter, one on top, one underneath. Note that the arms cannot move independently of each other. At the end of each actuator arm are the read and write heads.
