PROBLEM TO BE SOLVED: To suppress dust from being scattered in a drive even though a gap is formed over a screwing part when a magnetic circuit is fixed to a base about a disk drive for performing recording and reproduction processing to a magnetic disk by driving an actuator with a magnetic head provided by the magnetic circuit mounted on the base. SOLUTION: The magnetic disk drive having the magnetic circuit 15 for moving the magnetic head to a target track of the magnetic disk 11 by driving the actuator 22 with the magnetic head mounted, and the base 13 having a screwing part 25 where the magnetic circuit 15 is screwed is provided with a closing member 30 for closing a gapΔH formed between the magnetic circuit 15 and the screwing part 25 when the magnetic circuit 15 is screwed to the screwing part 25.
