Certain aspects of the present disclosure provide a ramp for a hard disk drive. The HDD ramp generally includes a ramp body having a head separator fin, a gimbal limiter adjacent to the head separator fin which is thicker than the head separator fin, and a first chamfer at a transition between a first surface of the gimbal limiter and a first surface of the head separator fin. A hard disk drive including such a HDD ramp and a method for using the HDD ramp are also disclosed.
1. A ramp for a hard disk drive (HDD), comprising: a ramp body comprising a head separator fin, a gimbal limiter adjacent to the head separator fin which is thicker than the head separator fin, and a first chamfer at a transition between a first surface of the gimbal limiter and a first surface of t
1. A ramp for a hard disk drive (HDD), comprising: a ramp body comprising a head separator fin, a gimbal limiter adjacent to the head separator fin which is thicker than the head separator fin, and a first chamfer at a transition between a first surface of the gimbal limiter and a first surface of the head separator fin. 2. The ramp of claim 1, wherein the ramp is formed of a monolithic body. 3. The ramp of claim 2, wherein the ramp comprises plastic. 4. The ramp of claim 3, wherein the plastic comprises polytetrafluoroethylene (PTFE). 5. The ramp of claim 1, wherein the first chamfer is disposed at an angle between 120 and 150 degrees to the first surface of the head separator fin. 6. The ramp of claim 5, wherein the first chamfer is disposed at an angle between 130 and 140 degrees to the first surface of the head separator fin. 7. The ramp of claim 1, wherein the ramp body has a plurality of head separator fins, a plurality of gimbal limiters with each gimbal limiter adjacent to a corresponding head separator fin and thicker than the corresponding head separator fin, and a chamfer at each transition between a first surface of each gimbal limiter and a first surface of the corresponding head separator fin. 8. The ramp of claim 1, wherein the ramp body has a second chamfer at a transition between a second surface of the gimbal limiter and a second surface of the head separator fin. 9. A hard disk drive (HDD) comprising: a magnetic disk;an actuator to move a head over the magnetic disk; anda ramp, wherein the ramp comprises a ramp body comprising a head separator fin, a gimbal limiter adjacent to the head separator fin which is thicker than the head separator fin, and a first chamfer at a transition between a first surface of the gimbal limiter and a first surface of the head separator fin. 10. The HDD of claim 9, wherein the ramp is formed of a monolithic body. 11. The HDD of claim 10, wherein the ramp comprises plastic. 12. The HDD of claim 11, wherein the plastic comprises polytetrafluoroethylene (PTFE). 13. The HDD of claim 9, wherein the first chamfer is disposed at an angle between 120 and 150 degrees to the first surface of the head separator fin. 14. The HDD of claim 13, wherein the first chamfer is disposed at an angle between 130 and 140 degrees to the first surface of the head separator fin. 15. The HDD of claim 9, wherein the ramp body has a plurality of head separator fins, a plurality of gimbal limiters with each gimbal limiter adjacent to a corresponding head separator fin and thicker than the corresponding head separator fin, and a chamfer at each transition between a first surface of each gimbal limiter and a first surface of the corresponding head separator fin. 16. The HDD of claim 9, wherein the ramp body has a second chamfer at a transition between a second surface of the gimbal limiter and a second surface of the head separator fin. 17. A method for preventing damage to a head gimbal assembly of a hard disk drive (HDD), comprising: parking a head of an HDD on a ramp of the HDD, wherein the ramp comprises a ramp body comprising a head separator fin, a gimbal limiter adjacent to the head separator fin which is thicker than the head separator fin, and a first chamfer at a transition between a first surface of the gimbal limiter and a first surface of the head separator fin. 18. The method of claim 17, wherein the ramp is formed of a monolithic body. 19. The method of claim 17, wherein the ramp body has a plurality of head separator fins, a plurality of gimbal limiters with each gimbal limiter adjacent to a corresponding head separator fin and thicker than the corresponding head separator fin, and a chamfer at each transition between a first surface of each gimbal limiter and a first surface of the corresponding head separator fin. 20. The method of claim 17, wherein the ramp body has a second chamfer at a transition between a second surface of the gimbal limiter and a second surface of the head separator fin.
