Abstract
A hard disk drive assembly which includes a limiter plate that is attached to an actuator arm. The limiter plate limits a movement of a flexure arm that is attached to a head. The head is coupled to a disk. The limiter plate limits the distance that the head can move away from the disk. Limiting the movement of the head may reduce the impact force associated with the head slapping the disk.
Claims20
A hard disk drive assembly, comprising:
- a disk that has a surface;
- a spin motor that rotates said disk;
- a head coupled to said surface of said disk;
- an actuator arm that has an e-block;
- a flexure arm that has a proximal end attached to said e-block of said actuator arm and a distal end attached to said head;
- 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 not attached to said flexure arm, said limiter plate has a proximal end attached to said e-block of said actuator arm and a distal end that is not in contact with said flexure arm during normal operation of the hard disk drive and which limits a movement of said flexure arm.

A hard disk drive assembly, comprising:
- a disk that has a surface;
- a spin motor that rotates said disk;
- an actuator arm that has an e-block which has a plurality of beams, each beam having a first side and a second side;
- a flexure arm that is attached to said first side of said beam;
- a head that is mounted to said flexure arm and coupled to said disk;
- 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 second side of said actuator arm beam and is not in contact with said flexure arm during normal operation of the hard disk drive and which limits a movement of said flexure arm.
