Abstract

디스크 드라이브의 스핀들 모터 회전 제어장치가 개시된다.An apparatus for controlling a spindle motor rotation of a disk drive is disclosed.

본 발명의 디스크 드라이브의 스핀들 모터 회전 제어장치는 스핀들 모터의 회전에 따라 소정의 검출신호를 출력하는 홀 센서와, 상기 홀 센서로부터의 출력신호를 입력받아 스핀들 모터의 회전을 제어하는 마이크로컴퓨터를 구비하는 스핀들 모터 회전 제어장치에 있어서, 상기 홀 센서와 마이크로컴퓨터 사이에는 상기 홀 센서로부터의 출력 신호를 입력받아 소정의 트리거 신호로 변환하여 출력하는 저역 필터가 설치되어 있다.A spindle motor rotation control apparatus for a disk drive of the present invention includes a hall sensor for outputting a predetermined detection signal in accordance with rotation of a spindle motor and a microcomputer for receiving rotation of the spindle motor and receiving an output signal from the hall sensor And a low-pass filter is provided between the hall sensor and the microcomputer for receiving an output signal from the Hall sensor and converting the output signal into a predetermined trigger signal.

이와 같은 본 발명의 디스크 드라이브의 스핀들 모터 회전 제어장치는 종래와 달리 저역 필터에 의해 스핀들 모터의 정지상태에 대응하는 소정의 트리거 신호를 마이크로컴퓨터의 입력신호로 제공함으로써, 스핀들 모터의 스핀들 서보를 정확하게 제어할 수 있는 한편 모터의 역회전을 방지할 수 있는 장점이 있다.The spindle motor rotation control apparatus of the disk drive of the present invention provides a predetermined trigger signal corresponding to the stop state of the spindle motor as an input signal of the microcomputer by means of a low pass filter unlike the prior art, And the reverse rotation of the motor can be prevented.
