일반적으로 콤팩트 디스크 플레이어(CDP)나 레이저 씨디롬(CD-ROM) 드라이버와 같은 각종 광디스크 플레이어(Optical Disk Player)는 레이저광을 디스크에 조사하여 상기 디스크에서 반사된 레이저빔(Laser Beam)을 검출하여 전기적인 신호로 변환시켜서 디스크면상의 기록내용을 재생하도록 하는 광픽업 조립체를 포함한다.In general, various optical disk players, such as a compact disk player (CDP) or a laser CD-ROM (CD-ROM) driver, irradiate a disk with a laser beam to detect a laser beam reflected from the disk, And an optical pickup assembly for converting the signal into a conventional signal to reproduce the recorded contents on the disk surface.

도 1을 참조하면, 종래의 광픽업 조립체는 요크 플레이트(10)와, 보빈(20)과, 서스펜션 와이어(30)를 구비한다.Referring to FIG. 1, a conventional optical pickup assembly includes a yoke plate 10, a bobbin 20, and a suspension wire 30.

상기 요크 플레이트(10)는 금속박판을 프레스가공하여 형성되며, 복수의 요크부(11)를 구비하고 있다. 상기 요크부(11)에는 마그네트(12)가 접착되어 고정된다.The yoke plate 10 is formed by pressing a metal thin plate and includes a plurality of yoke portions 11. The magnet 12 is bonded and fixed to the yoke portion 11.

상기 보빈(20)은 요크 플레이트(10)의 상방에 위치하며, 그 보빈(20)의 상측에는 광원(미도시)으로부터 출사된 레이저광을 디스크에 집속시키기 위한 대물렌즈(21)가 설치된다. 그리고, 보빈(20)의 측면에는 마그네트(12)와 대면하는 위치에 복수의 코일부재(22)가 설치된다. 상기 코일부재(22)의 일단부는 보빈(20)에 설치된 코일회로기판(23)에 납땜된다.The bobbin 20 is positioned above the yoke plate 10, and an objective lens 21 is installed above the bobbin 20 to focus laser light emitted from a light source (not shown) onto a disk. In addition, a plurality of coil members 22 are provided on the side surface of the bobbin 20 at a position facing the magnet 12. One end of the coil member 22 is soldered to the coil circuit board 23 provided on the bobbin 20.

상기 서스펜션 와이어(30)는 보빈(20)을 요크 플레이트(10)에 대해 부상된 상태를 유지하면서 유동가능하도록 지지한다. 서스펜션 와이어(30)는, 통상적으로 4개가 설치되며 각각의 일단은 상기 코일회로기판(23)에 납땜되고, 타단은 요크 플레이트(10)에 고정된 홀더(31)에 납땜되어, 그 코일회로기판(23)을 통해서 코일부재(22)와 전기적으로 연결된다.The suspension wire 30 supports the bobbin 20 to be flowable while maintaining the floating state with respect to the yoke plate 10.
