Abstract

본 발명은 하드디스크 드라이브에 관하여 개시한 것으로서, 본 발명에 의한 하드디스크 드라이브는 액튜에이터 결합체(202)를 형성함에 있어서 종래 포함되던 커버(12)를 제외하고, 피봇(24a)과 베이스(21)의 핀홀(17) 및 하부 요크부재(26)를 중심으로 상부 요크부재(25)를 추가로 이용하여 결합체를 형성한다. 이에 따라 조립작업시 커버(22)를 덮지 않은 상태에서 액튜에이터 결합체를 형성하게 되므로, 피봇(24a)과 핀홀(27) 및 상·하부 요크부재(25)(26)의 중심선을 일치시키기가 용이하여 불안정한 조립상태로 인한 분절가루 등의 발생을 방지할 수 있어서 하드디스크 드라이브의 성능향상을 도모할 수 있으며, 이와 동시에 조립 작업성을 높일 수 있어서 생산성 향상도 기대할 수 있는 장점을 가진다. 그리고, 조립후의 상태가 견고하여 진동 등 외부로부터의 충격을 용이하게 흡수할 수 있어서 고용량과 고기록밀도를 가지는 디스크 드라이브에 적용이 가능한 장점을 가지도록 한 것이다.The present invention discloses a hard disk drive, wherein the hard disk drive according to the present invention includes the pivot 24a and the base 21 except for the cover 12 which is conventionally included in forming the actuator assembly 202. The upper yoke member 25 is further used around the pinhole 17 and the lower yoke member 26 to form an assembly. Accordingly, since the actuator assembly is formed without covering the cover 22 during assembly, the center line of the pivot 24a and the pinhole 27 and the upper and lower yoke members 25 and 26 can be easily matched. It is possible to prevent the occurrence of segmental powder due to the unstable assembly state, thereby improving the performance of the hard disk drive, and at the same time, it is possible to increase the workability of the assembly, thereby improving productivity. In addition, since the state after assembly is robust, shock from the outside such as vibration can be easily absorbed, so that it can be applied to a disk drive having a high capacity and a high recording density.
