Abstract

본 발명은 광픽업 액츄에이터의 부공진 방지 마그네트에 관한 것으로서, 외측 요크(114)에 끼워져 설치되는 끼움홈(132)이 형성된 연성의 재질로 된 마그네트(130)를 사용하여 포커싱 조정코일(124) 및 트랙킹 조정코일(126)과 마그네트(130)간에 작용하는 반발력에 의해 발생되는 진동을 흡수하여 부공진을 방지하고 조립작업을 간편하게 함으로써, 액츄에이터의 품질과 생산성을 향상시키기 위한 것이다.The present invention relates to an anti-resonant magnet of an optical pickup actuator, wherein the focusing adjustment coil 124 and the magnet 130 are made of a flexible material having a fitting groove 132 inserted and installed in the outer yoke 114. It is to improve the quality and productivity of the actuator by absorbing the vibration generated by the repulsive force acting between the tracking adjustment coil 126 and the magnet 130 to prevent negative resonance and simplify the assembly operation.
