광학헤드는 디지털 오디오 및 비디오 장치의 핵심부품으로서 일반 가전제품에서부터 컴퓨터 기억장치 및 게임기까지 광범위하게 응용되고 있으며, 광미디어의 수요가 확대됨에 따라 그 수요도 급속도로 증가되는 추세이다. 본 논문에서는 광학헤드의 핵심 구성요소인 포커스 및 트랙킹 서보용 2축 구동부를 와이어 부동형 외팔보 형태로 설계하고, 시뮤레이션 및 시제작 특성 분석을 통하여 그 설계 타당성을 검증하였다. 또한, 시제작 특성 분석을 통하여, 설계상의 원인외에 2축 구동부의 성능에 악영향을 미치는 조립공정의 인자를 파악하였다. The optical heads as the key parts of digital audio/video players are applied extensively from general household electric appliances to computer memory or game apparatuses, and the demand of them tends to be increased according to the extension of optical medium market. In this paper, the 2-axis actuator, the key component for focus servo and tracking servo of the optical head is designed as a type of the cantilever suspended by 4 wires. The design propriety is verified through its simulation and the characteristic analysis of its mock-ups. The other factors which influence the performance of 2-axis actuators besides the design factors of them, are also verified through the mock-up analysis.

The world economy is currently moving into a new era of free trade scheme by establishing the WTO. And also, regional economic cooperation and integration have acquired special significance since the formation and successful functioning of trade bloc would create more trade among member countries. Responding to these changes in the world economic environment, countries in the Southeast Asia have tried to promote intra-regional economic ties by the launching of a scheme towards ASEAN Free Trade Area(AFTA). Traditionally, intra-regional trade among ASEAN countries was insignificant with exception of Singapore, because they produce more or less the same natural resources and raw materials. Thus, regional cooperation among ASEAN countries through AFTA aimed to facilitate more cost-effective industrial and production activities in the region, providing firms with greater synergy and competitive edge in servicing both global and regional markets. In order to investigate the effects of regional integration represented by AFTA, the paper chooses Malaysia of which trade volume is largest in the region except for Singapore. Results of estimation of trade intensity indices show that Malaysia’s trade relationship with intra-ASEAN region countries have notably strengthened in current years after the launching of AFTA. Based on the findings of changes in trade structure in Malaysia, we might argue that intra-regional trade integration among ASEAN countries will more facilitate for the future.

본 논문에서는 레이저 다이오드, 포토 다이오드, 그레이팅 렌즈, 빔 스프릿터가 반도체 공정으로 직접화된 홀로그램 레이저 다이오드와 4 와이어 부동형 엑츄에이터를 이용하여, 시장성이 풍부한 일반 오디오용 광학 픽업을 설계하였다. 또한, 이러한 홀로그램 레이저 다이오드의 특성을 이용하여 초간편 광학계를 구현하므로서, 기존외 제품 대비 조립성과 생산성을 향상시키고, 취부 부품의 수를 줄이고 형상을 단순화하였다. In this paper, the optical pick-up used for general audio/video players having more market share than the others is designed with 4-wire suspension type actuator and the hologram laser diode which laser diode, photo diode, beam splitter, and grating lens are integrated in. This optical pick-up is designed in very simple optical system with the characteristics of hologram laser diode. Thus, it has high productivity, the number of the parts is reduced, and also the shape of the assembling parts becomes simple.
