Abstract

1. 청구범위에 기재된 발명이 속하는 기술분야1. TECHNICAL FIELD OF THE INVENTION

본 발명은 액츄에이터의 아암부분을 전자석으로 제어하여 헤드 슬라이더의 비행높이를 일정하게 유지시키고 헤드와 메디아 간에 갭(Gap)을 주어 접촉에 의한 손상을 방지하기 위한 하드디스크 드라이브의 액츄에이터 장치에 관한 것이다.The present invention relates to an actuator device of a hard disk drive for controlling the arm portion of the actuator with an electromagnet to maintain a constant flying height of the head slider and to prevent a contact damage by giving a gap between the head and the media.

2. 발명이 해결하려고 하는 기술적 과제2. The technical problem to be solved by the invention

본 발명은 메디아상의 전영역에서 헤드가 일정한 높이를 유지하면서 비행하도록 하고, 헤드의 파킹시 충격을 감안하여 안전한 파킹을 이루도록 하며, 헤드의 비행 높이 제어를 용이하게 할 수 있도록 하는 액츄에이터 장치를 제공하는데 있다.The present invention provides an actuator device that allows the head to fly while maintaining a constant height in all areas on the media, to achieve safe parking in consideration of the impact of the parking of the head, and to facilitate the control of the flying height of the head. have.

3. 발명의 해결방법의 요지3. Summary of Solution to Invention

본 발명은 플라스틱 재질의 액츄에이터 아암에 금속 바아(Metal Bar)를 심고, 아암과 아암 사이에는 플라스틱 판을 두고 그 위에 상기 금속 바아와 대향하도록 전자석을 설치하여 헤드가 디스크상을 비행할 시 전자석으로부터의 자력으로 아암을 당겨 상기 헤드가 목표고도를 유지하도륵 제어 한다.According to the present invention, a metal bar is planted on an actuator arm made of plastic, and a plastic plate is placed between the arm and the arm, and an electromagnet is installed to face the metal bar. The arm is pulled by magnetic force to control the head to maintain the target altitude.

4. 발명의 중요한 용도4. Important uses of the invention

본 발명은 헤드가 디스크의 파킹존에 붙어있다가 부상하는 것이 아니라 반대로 헤드가 디스크로부터 멀리 떨어져 있어서 충격으로부터 안전한 보호를 할 수 있고, 전자석의 자력에 의해 디스크와 일정한 비행높이를 유지하도록 콘트롤함으로써 전 영역에 대하여 균일한 진폭을 유지하도륵 함에 따라 드라이브의 성능이 향상되는 잇점이 있다.According to the present invention, the head is not attached to the parking zone of the disk and is not injured. On the contrary, the head is far from the disk to provide a safe protection from the impact. Maintaining a uniform amplitude over the area has the advantage of improving drive performance.
