Abstract

광디스크 드라이브에 있어서, 특히 수직과 수평방향의 진동을 하나의 댐퍼구조로서 효과적으로 흡수하게 하며, 그 댐퍼의 구조에 따라 제작/조립성이 개선되어 생산성을 향상시킨 광디스크 드라이브의 댐핑장치에 대해 개시한다. 이 댐퍼는 댐퍼내부에 수직방향의 진동을 흡수하는 수직진동 흡수부와 수평방향의 진동을 흡수하는 수평진동 흡수부가 각각 구비되어 외부로부터의 진동을 흡수하게 된다. 이로서 하나의 댐퍼에서 수평/수직방향의 진동을 효과적으로 제진할 수 있게 되며, 댐퍼를 날개로 생산하지 않고 필요한 길이마다 절단하여 사용할 수 있게 되어 생산성을 증대시킬 수 있게 된다.
