    • A reproducing apparatus for reproducing data recorded on an optical record carrier is provided having an improved lifetime of the laser light source used to read the data. The reproducing apparatus includes a laser driver unit that is adapted to drive the light output of the laser light source to change from a reading mode, in which data recorded in the optical disc is being read for being reproduced, into a laser lifetime extension mode when an operation of reading said data is paused. In the laser lifetime extension mode, the laser light source is driven to emit a pulsed light output, therefore, the amount of time in which the laser light source is on without being needed is reduced and the lifetime of the laser light source is improved.
    • 提供了一种用于再现记录在光学记录载体上的数据的再现装置,其具有用于读取数据的激光光源的寿命改善。 再现装置包括:激光驱动单元,其适于驱动激光光源的光输出,以便将记录在光盘中的数据正在被读取以便再现的读取模式改变为激光寿命延长模式,当激光寿命延长模式为 暂停读取所述数据的操作。 在激光寿命延长模式中,激光源被驱动以发出脉冲光输出,因此,不需要激光光源所在的时间量被减少,并且提高了激光光源的寿命。
