Abstract
본 발명은 광기록 장치에 관한 것으로, 특히 디스크에 데이타를 기록할 시 디스크의 회전변동에 따른 데이타 기록 에러를 방지할 수 있는 광기록 시스템의 가변속 기록장치에 관한 것으로, 종래에는 데이타의 기록시 편심 등에 의하여 디스크의 회전속도가 변동하였을 경우에 회전속도의 변동이 얻어질때까지 기록 대기상태에 놓이게 되며, 스핀들 회전수를 변화시키지 못하게 될 경우에는 그대로 기록하게 됨으로써 기록 데이타의 에러가 발생하게 되고, 이러한 에러를 방지하기 위해서는 토크가 큰 모터를 사용하게 되면 모터의 크기가 증대되어 부피가 그만큼 증가되는 문제점이 있었으나, 본 발명에서는 디스크의 회전속도의 변동을 검출하여 디스크의 회전속도가 느려지면 레이저의 주사기간을 늘리고, 반면에 회전속도가 빨라지면 레이저의 주사기간을 단축시켜 정상적인 데이타를 기록하므로써 광기록장치의 성능과 신뢰성을 높힘과 동시에 고속의 기록 및 토크가 큰 스핀들 모터를 사용하지 않아도 되므로 장치의 소형화를 이룰수 있는 효과가 있게 된다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an optical recording apparatus, and more particularly, to a variable speed recording apparatus of an optical recording system capable of preventing a data recording error caused by a rotational change of a disk when data is recorded on a disk. When the rotational speed of the disk changes due to the rotation of the disk, the recording medium is placed in the recording standby state until the variation of the rotational speed is obtained. When the rotational speed of the disk cannot be changed, the data is recorded as it is, and an error of the recording data occurs. In order to prevent an error, when the motor having a large torque is used, the size of the motor is increased and the volume is increased. However, in the present invention, when the rotation speed of the disk is slowed down by detecting a change in the rotation speed of the disk, laser scanning is performed. Increasing the duration, while increasing the speed of the laser scan The speed was not required at the same time as nophim the performance and reliability of an optical recording apparatus using a large spindle motor and the torque of the high-speed recording By recording the normal data between, so it is possible that the effect and achieve miniaturization of the device.
