Abstract
In the present invention, an intermediate member having a hardness different than that of a pivot is provided. According to this structure, the pivot is in contact with the intermediate member, and rubs the intermediate member to control the sliding of the pivot. Since the intermediate member has a different hardness than the pivot, these elements can better bear the acceleration of a head suspension in high speed operation. Moreover, generation of dust can be controlled and reliability can also be improved.
Claims14
A head suspension for use adjacent a disk medium comprising;
- a first portion having a head slider and a first surface;
- and
- a second portion having a gimbal and a second surface in contact with said first surface;
- said first surface and said second surface having a different degree of hardness.
A head suspension for use adjacent a disk medium comprising:
- a load beam for giving a load in the disk medium direction to a head slider;
- a gimbal mounted to said load beam to mount said head slider to any one surface;
- a pivot formed on the other surface of said gimbal to support said head slider on a point;
- and
- an intermediate member, having a hardness higher than that of said pivot, between the surface of the load beam opposed to said pivot and said pivot.
A head suspension comprising;
- a load beam for giving a load in the disk medium direction to a head slider;
- a gimbal mounted to said load beam to mount said head slider to any one surface;
- a pivot formed on the surface opposed to said gimbal in said load beam to support said head slider on a point;
- and
- an intermediate member, having a hardness higher than said pivot, formed between said pivot and the surface opposed to said pivot in said gimbal.
A head suspension comprising;
- a load beam extending in the rotating direction of a disk to give a load in said disk direction to the head slider;
- a gimbal mounted to said load beam to mount on its one surface said head slider;
- a pivot formed on the other surface of said gimbal to support said head slider on a point;
- and
- a recess formed on the surface opposed to said gimbal in said load beam, such that said pivot is embedded therein.
A head suspension comprising;
- a load beam extending in the rotating direction of a disk to give a load in said disk direction to a head slider;
- a gimbal mounted to said load beam to mount on its one surface said head slider;
- a pivot formed on the surface opposed to said gimbal in said load beam to support said head slider on the point;
- and
- a recess formed on the other surface of said gimbal, said pivot being embedded therein.
