    • A driving voltage of a laser diode provided in an optical disc apparatus is properly set based on an operating environment thereof to reduce unnecessary power consumption and heat generation. A temperature detector detects the temperature inside a pickup. A memory stores a value of the voltage to be supplied to a laser driver, the voltage corresponding to each of various operating environments. A controller refers to voltage values stored in the memory to set the voltage to be supplied to the laser driver based on a current operating environment. Operating environment parameters includes at least one of the temperature, operation mode, recording rate, and accumulated light emission time. The voltage value to be stored in the memory is a value of the voltage at which electric power consumed by the laser driver becomes smallest in the operating environment.
    • 基于其操作环境适当地设置设置在光盘装置中的激光二极管的驱动电压,以减少不必要的功率消耗和发热。 温度检测器检测拾音器内部的温度。 存储器存储要提供给激光驱动器的电压的值,对应于各种操作环境中的每一个的电压。 控制器是指存储在存储器中的电压值,以基于当前的操作环境来设置要提供给激光驱动器的电压。 操作环境参数包括温度,操作模式,记录速率和累积发光时间中的至少一个。 要存储在存储器中的电压值是在操作环境中由激光驱动器消耗的电力变得最小的电压的值。

    • In an optical recording and reproducing apparatus which forms at least first and second light spots on a track of an optical recording medium to record, reproduce or erase information, a movable range of the second light spot is limited to less than one half of a track pitch, normal to the track, from the track to prevent tracks other than a target track from being miserased, misrecorded or misreproduced. When a deviation of the second light spot from the target track exceeds a predetermined amount, light emission of the second light spot is stopped to prevent a track other than the target track from being miserased, misrecorded or misreproduced. When the deviation of the second light spot from the target track exceeds the predetermined amount, the second light spot is returned to a neutral position to prevent a track other than the target track from being miserased, misrecorded or misreproduced.
    • 在光学记录和再现装置中,其至少在光学记录介质的轨道上形成第一和第二光斑以记录,再现或擦除信息,第二光斑的可移动范围被限制在小于轨道的一半 从轨道正常的轨道,以防止目标轨道以外的轨迹被歪曲,误记或错误地产生。 当第二光点与目标轨迹的偏差超过预定量时,停止第二光点的发光,以防止除了目标轨迹以外的轨迹被误导,误记或错误地产生。 当第二光点与目标轨道的偏差超过预定量时,第二光点返回到中立位置,以防止目标轨道以外的轨迹被误导,误记或错误地产生。
