Abstract
A hard disk drive assembly that includes a device for limiting a movement of a head of a head gimbal assembly from a surface of a disk. The head is coupled to the disk and attached to a suspension of the head gimbal assembly. The invented device limits a distance that the head can move away from a surface of the disk. Limiting the distance that the head can move away from the surface of the disk, may reduce the impact force associated with the head slapping the disk, which may reduce damage associated with head slapping.
Claims13
A hard disk drive assembly, comprising:
- a disk that has a surface;
- a spin motor that rotates said disk;
- a head that is coupled to said disk surface;
- a suspension that is attached to said head, said suspension having an elbow;
- an actuator arm which has a beam that is attached to said suspension, said beam having a distal end that extends beyond said elbow of said suspension to limit a movement of said head;
- and
- a voice coil motor that is coupled to said actuator arm and moves said head across said surface of said disk.
A hard disk drive assembly, comprising:
- a disk that has a surface;
- a spin motor that rotates said disk;
- a head that is coupled to said disk surface;
- a suspension that is attached to said head;
- an actuator arm which has a beam that is attached to said suspension;
- a voice coil motor that is coupled to said actuator arm and moves said head across said surface of said disk;
- and
- a limiter plate that is attached to said suspension and said actuator arm, said limiter plate limits a movement of said head.
