Abstract
An HAA has at least one HGA, each including a head slider with at least one head element, a suspension for supporting the head slider, and a lead conductor member electrically connected with the at least one head element, and a main body including at least one actuator arm for supporting the at least one HGA. The main body of the HAA is made of a metal material, and a surface of the main body is coated by a DLC film.
Claims24
A head arm assembly comprising:
- at least one head gimbal assembly, each including a head slider with at least one head element, a suspension for supporting said head slider, and a lead conductor member electrically connected with said at least one head element;
- and
- a main body including at least one actuator arm for supporting said at least one head gimbal assembly, said main body being made of a metal material, and a surface of said main body being coated by a diamond-like carbon film.
A disk apparatus provided with a head arm assembly comprising:
- at least one head gimbal assembly, each including a head slider with at least one head element, a suspension for supporting said head slider, and a lead conductor member electrically connected with said at least one head element;
- and
- a main body including at least one actuator arm for supporting said at least one head gimbal assembly, said main body being made of a metal material, and a surface of said main body being coated by a diamond-like carbon film.
A manufacturing method of a head arm assembly comprising the steps of:
- preparing at least one head gimbal assembly, each including a head slider with at least one head element, a suspension for supporting said head slider, and a first lead conductor member electrically connected with said at least one head element;
- preparing a main body of the head arm assembly, said main body including at least one actuator arm and being made of a metal material;
- depositing a diamond-like carbon film to coat a surface of said main body;
- attaching a second lead conductor member to said main body coated by the diamond-like carbon film;
- mounting said at least one head gimbal assembly onto said at least one actuator arm of said main body coated by the diamond-like carbon film;
- and
- electrically connecting said first lead conductor member with said second lead conductor member.
