飞利浦(PHILIPS)MKH—320 CD机芯采用CDM4/19光学系统和第三代集成电路,社会拥有量较大。其径向机构与寻迹跟踪机构采用同一音圈电机,激光头的运动为摇臂控制,由径向电机驱动摇臂动作,具有寻曲速度快、精度高等优点。采用该机芯的有星球XA—153、世达CD—913、星河CD—420和深飞AK696等CD机。 1.电路分析整机电路由光电信号处理器、径向误差处理器、数字信号处理器、音频电路、系统控制及电源电路等组
PHILIPS MKH-320 CD movement using CDM4 / 19 optical system and third-generation integrated circuits, the community has a larger share. The radial mechanism and tracing tracking mechanism adopt the same voice coil motor. The movement of the laser head is controlled by a rocker arm, and the radial motor drives the rocker arm to move. The invention has the advantages of fast seeking speed and high precision. Using the movement of the planet XA-153, the world of CD-913, Galaxy CD-420 and deep-flight AK696 and other CD players. 1. Circuit Analysis The whole circuit consists of optical signal processor, radial error processor, digital signal processor, audio circuit, system control and power circuit group
