    • The present invention relates to a reproducing apparatus which, in a case where a burst error has occurred, corrects an error preceding a synchronization pattern detected thereafter to have less errors. A bit slip judging section 81 in a bit slip correcting section 53 calculates a bit slip correction amount and a bit slip correction position on the basis of phase error signals detected by a phase error detecting section 51, synchronization pattern signals detected by a synchronization detecting section 52, reproduced clocks and detected data. A FIFO control section 82 controls a FIFO buffer 83 on the basis of the bit slip correction amount and the bit slip correction position, to perform bit slip correction. As a result, in the case where a burst error has occurred, an error preceding a synchronization pattern detected thereafter is corrected, whereby an error reduction can be implemented. The present invention is applicable to a reproducing apparatus.
    • 本发明涉及在发生突发错误的情况下,对其后检测到的同步模式之前的错误进行校正以具有更少错误的再现装置。 位移校正部分53中的位滑动判断部分81基于由相位误差检测部分51检测的相位误差信号计算位滑差校正量和位滑差校正位置,同步检测部分检测到的同步模式信号 52,再现时钟和检测数据。 FIFO控制部分82基于位滑差校正量和位滑差校正位置控制FIFO缓冲器83,以进行位滑动校正。 结果,在发生突发错误的情况下,纠正了之后检测到的同步模式之前的错误,从而可以实现错误减少。 本发明可应用于再现装置。
