A low profile head support device has excellent shock resistance and can apply necessary and sufficient biasing forces to a head and a disk drive using the same. The head support device includes a head; head suspension 2 to suspend the head; base arm 4 pivotally secured to actuator axis 10, suspending the head suspension; pivot fulcrum 5 to movably suspend head suspension 2; and spring member 2e to apply a biasing force to head suspension 2, wherein pivot fulcrum 5 is disposed on base arm 4. The head support device can be used in various kinds of information devices such as data processing devices, magneto optical disk drives, optical disk drives or the like.
