Abstract
1. 청구범위에 기재된 발명이 속한 기술분야1. TECHNICAL FIELD OF THE INVENTION
디스크 구동 기록장치의 스핀들모터에 관한 것으로, 특히 데이타 리드/라이트시 디스크 기록매체를 구동시키는 스핀들모터가 접속회전하는가를 점검하기 위한 방법에 관한 것이다.The present invention relates to a spindle motor of a disc drive recording apparatus, and more particularly to a method for checking whether or not a spindle motor for driving a disc recording medium is connected and rotated during data read / write.
2. 발명이 해결하려고 하는 기술적 과제2. The technical problem to be solved by the invention
스핀들모터의 회전속도를 주기적으로 점검하여 스핀들모터의 회전속도 저하로 발생할 수 있는 디스크 구동기록장치의 오동작을 미연에 방지하여 디스크 구동 기록장치의 신뢰성을 확보함에 있다.By periodically checking the rotational speed of the spindle motor, it is possible to secure the reliability of the disk drive recording device by preventing the malfunction of the disk drive recording device which may occur due to the reduction of the rotational speed of the spindle motor.
3. 발명의 해결방법의 요지3. Summary of Solution to Invention
디스크 구동 기록장치에 있어서 상기 장치의 모터구동부로 부터 레디신호가 수신되는 경우 이에 응답하여 규정 타임값과 서브 인덱스 카운터값을 비교하여 스핀들모터의 회전속도가 정속회전 범위이내일 경우 서보 알고리즘을 수행하는 반면, 상기 스핀들모터의 회전속도 저하로 인해 발생될 수 있는 데이타 리드/라이트 오동작을 방지함을 특징으로 한다.In the disc drive recording apparatus, when a ready signal is received from the motor driver of the apparatus, the servo algorithm performs a servo algorithm when the rotation speed of the spindle motor is within the constant speed range by comparing the prescribed time value and the sub index counter value. It is characterized in that to prevent the data read / write malfunction that may occur due to the rotational speed of the spindle motor.
4. 발명의 중요한 용도4. Important uses of the invention
스핀들모터의 정속회전이 요구되는 디스크 구동 기록장치에 유용히 사용될 수 있다.It can be usefully used for a disk drive recording apparatus which requires a constant speed rotation of the spindle motor.
