Abstract

본 발명은 오디오헤드의 애지머스(Azimuth) 자동제어장치에 관한 것으로, 특히 오디오테이프로 부터 오디오신호와 동기신호를 독출하는 오디오 헤드부(10)와, 이 오디오헤드부(10)에서 독출된 신호들을 처리하는 DSP(Digital Signal Processor)부(20)와, 이 DSP부(20)에서 출력되는 동기신호를 검출하여 애지머스(Azimuth)의 뒤틀림 정도를 판단하여 애지머스 모터를 구동하기 위한 제어신호를 발생하는 마이컴(30)과, 이 마이컴(30)의 제어신호에 의해 오디오헤드의 애지머스(Azimuth)를 보정하기 위한 제어 전압을 발생하는 애지머스 모터 구동부(40)로 구성되어, 테이프의 동기신호로부터 애지머스(Azimuth)의 뒤틀림 정도를 측정하여 애지머스 모터를 구동하여 오디오 헤드의 애지머스를 보정하여 테이프의 오디오 트랙을 정확히 추적하도록 함으로써, 깨끗한 음질을 제공하도록 하는 효과가 있다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an azimuth automatic control apparatus for an audio head, and more particularly, an audio head unit 10 for reading an audio signal and a synchronization signal from an audio tape, and an audio head unit 10 read out from the audio head unit 10. Digital signal processor (DSP) unit 20 for processing signals, and a synchronization signal output from the DSP unit 20 to determine the degree of distortion of the azimuth (Azimuth) control signal for driving the azimuth motor And azimuth motor driver 40 for generating a control voltage for correcting the azimuth of the audio head according to the control signal of the microcomputer 30. By measuring the degree of warpage of the Azimuth from the signal, the azimuth motor is driven to correct the azimuth of the audio head so that the audio tracks on the tape can be accurately tracked, providing clean sound quality. It is effective to lock.
