    • Disclosed is a method of reproducing optical information by applying laser light to the medium while rotating a recording medium having concentric information tracks or a spiral information track so that the linear velocity of the medium is constant, and thereby reproducing the information recorded on the recording medium by the reflected light. In this method, in moving a reproduction radial position to a second radial position different from the current position, a laser power is changed to second laser power, which is different from current laser power, and then the light spot is moved to the second radial position. This method can prevent degradation of a medium in reproduction light resistance caused by substantially high power reproduction, and erasing or destruction of already recorded data that may be caused, in high-speed recording of a rewritable-type or write-once-type optical disc, when the linear velocity at the time of reproduction becomes slow, e.g. , in an access operation at the time of reproduction with a constant linear velocity and in a return operation from rotational stop due to a standby state.
    • 公开了一种通过在旋转具有同心信息轨道或螺旋信息轨道的记录介质的同时向介质施加激光以使介质的线速度恒定从而再现记录在记录介质上的信息来再现光学信息的方法 通过反射光。 在这种方法中,在将再现径向位置移动到与当前位置不同的第二径向位置时,将激光功率改变为与当前激光功率不同的第二激光功率,然后将光斑移动到第二径向 位置。 这种方法可以防止在可重写型或一次写入式光盘的高速记录中由于基本上高功率再现引起的再现光阻中介质的劣化,以及擦除或破坏可能引起的已经记录的数据 当再现时的线速度变慢时,例如, 在以一定的线速度进行再现时的访问操作和由于待机状态的旋转停止的返回操作。

    • Means is provided that produces stabilized trial write results when, for example, servo misalignments are caused due to deviations on an optical disc that requires trial writes at high linear velocity. A recording method produces a recording parameter in the event of recording information into an arbitrary address position in the manner that a recording parameter is obtained through a predetermined calculation method from the results of learning of recording parameters on two or more zones of the optical disc where the linear velocities are different form one another. In a zone where the linear velocity is low, the method determines an optimal recording parameter from a jitter value of a reproduced signal waveform generated in a trial write. In a zone where the linear velocity is high, the method determines an optimal recording parameter in accordance with information obtainable from an amplitude value of a reproduced signal generated in a trial write.
