Claims
- 1. A magnetic disk drive comprising:a magnetic head slider; a load beam for supporting said magnetic head slider; an actuator arm for mounting said load beam and moving said magnetic head slider via said load beam to the surface of a magnetic disk; a load/unload mechanism for detaching said magnetic head slider from the surface of said magnetic disk or moving said magnetic head slider thereto; a restraining part which catches and restrains displacement of said actuator arm in a vertical direction to said magnetic disk when said magnetic head slider is unloaded; and wherein a gap between said actuator arm and said restraining part is narrower than a gap between said actuator arm and said magnetic disk.
- 2. A magnetic disk drive according to claim 1, wherein said restraining part is out of contact with said actuator arm when no impact is applied to said magnetic disk drive.
- 3. A magnetic disk drive according to claim 1, wherein said restraining part only contacts said actuator arm when impact is applied to said magnetic disk drive.
- 4. A magnetic disk drive according to claim 1, wherein said restraining part restrains only displacement of said actuator arm in a direction towards said magnetic disk.
- 5. A magnetic disk drive comprising:a magnetic head slider; a load beam for supporting said magnetic head slider; an actuator arm for mounting said load beam and moving said magnetic head slider via said load beam to the surface of a magnetic disk; a load/unload mechanism for detaching said magnetic head slider from the surface of said magnetic disk or moving said magnetic head slider thereto; a restraining part which catches and restrains displacement of said load beam in a vertical direction to said magnetic disk when said magnetic head slider is unloaded; and wherein a gap between said load beam and said restraining part is narrower than a gap between said load beam and said magnetic disk.
- 6. A magnetic disk drive according to claim 5, wherein said restraining part is out of contact with said load beam when no impact is applied to said magnetic disk drive.
- 7. A magnetic disk drive according to claim 5, wherein said restraining part only contacts said load beam when impact is applied to said magnetic disk drive.
- 8. A magnetic disk drive according to claim 5, wherein said restraining part restrains only displacement of said load beam in a direction towards said magnetic disk.
- 9. A magnetic disk drive comprising:a magnetic head slider; a load beam for supporting said magnetic head slider; an actuator arm for mounting said load beam and moving said magnetic head slider via said load beam to the surface of a magnetic disk; a load/unload mechanism for detaching said magnetic head slider from the surface of said magnetic disk or moving said magnetic head slider thereto; a first restraining part which catches and restrains displacement of said actuator arm in a vertical direction to said magnetic disk and a second restraining part which catches and restrains displacement of said load beam in a vertical direction to said magnetic disk when said magnetic head slider is unloaded; and wherein a gap between said actuator arm and said first restraining part is narrower than a gap between said actuator arm and said magnetic disk.
- 10. A magnetic disk drive according to claim 9, wherein a gap between said load beam and said second restraining part is narrower than a gap between said load beam and said magnetic disk.
- 11. A magnetic disk drive according to claim 9, wherein said first restraining part is out of contact with said actuator arm and said second restraining part is out of contact with said load beam, respectively, when no impact is applied to said magnetic disk drive.
- 12. A magnetic disk drive according to claim 9, wherein said first restraining part only contacts said actuator arm and/or said second restraining part only contacts said load beam when impact is applied to said magnetic disk drive.
- 13. A magnetic disk drive according to claim 9, wherein said first restraining part restrains only displacement of said actuator arm and said second restraining part restrains only displacement of said load beam, respectively, in a direction towards said magnetic disk.
