    • The present invention makes it possible to reproduce reproduction images without a break without having to use any additional identification information even when real-time recorded data is not completely continuous. A control circuit references a data identification flag (“Recording Type”) which is attached to each sector of reproduction data to indicate the type of recorded data, and counts the number of sectors to which the data identification flag representing real-time recorded data is attached. When the count is not smaller than a threshold value, the control circuit reproduces all the sectors of the target reproduction block in a real-time reproduction mode. In the real-time reproduction mode, the control circuit masks a portion of reproduction data that is found to be defective, changes the value of the defective data to 0 (zero), and transfers the resulting reproduction data to a host device.
    • 即使在实时记录数据不是完全连续的情况下,本发明也可以不间断地再现再现图像,而不必使用任何附加的识别信息。 控制电路参考附加到每个再现数据扇区的数据识别标志(“记录类型”),以指示记录数据的类型,并且对表示实时记录数据的数据识别标志的扇区数进行计数 附上。 当计数不小于阈值时,控制电路在实时再现模式中再现目标再现块的所有扇区。 在实时再现模式中,控制电路遮蔽发现有缺陷的再现数据的一部分,将缺陷数据的值改变为0(零),并将所得到的再现数据传送到主机设备。
