    • There is provided an optical disc device including an objective lens, a lens actuator for driving the objective lens, a light-receiving unit, and a system control unit which determines, at startup, the values of parameters to be set for recording or reproducing data in or from the respective information layers, and performs setting and management of recording inhibition or reproduction inhibition for the respective information layers, wherein, even when an error occurs because the values of the parameter groups for the respective layers cannot be determined in an optical disc having laminated plural information layers, recording or reproduction can be performed for at least the layers for which the parameters can be correctly determined, without stopping the startup. Thereby, the states of the respective information layers are managed for each information layer, and reproduction or recording operation is rapidly started in the respective layers to effectively utilize the multilayer disc.

    • A transfer start/end detecting section detects timing at which a DMARQ signal becomes an H level or an L level. A transfer time-measuring section measures a transfer time during which data transfer is actually performed within a period in which a predetermined number of data blocks are transferred. A transfer byte count-measuring section measures a transferred byte count of data that have successfully been transferred. An effective data transfer rate-computing section computes an effective data transfer rate by dividing the transferred byte count by the transfer time. A transfer rate-comparing section compares the effective data transfer rate with a transfer rate that is one step slower than a current transfer rate output from a selectable transfer rate-storing section. If the former is slower, a transfer rate-switching section switches to the transfer rate that is one step slower. A large decrease in the effective data transfer rate caused by data corruption is prevented.
    • 传送开始/结束检测部分检测DMARQ信号变为H电平或L电平的定时。 传送时间测量部测量在传送预定数量的数据块的时间段内实际执行数据传送的传送时间。 传输字节计数部分测量成功传输的数据的传输字节数。 有效的数据传输速率计算部分通过将传送的字节数除以传送时间来计算有效数据传送速率。 传输速率比较部分将有效数据传输速率与从可选择的传送速率存储部分输出的当前传输速率慢一步的传送速率进行比较。 如果前者较慢,则传输速率切换部分切换到慢一步的传输速率。 防止数据损坏导致的有效数据传输速率大幅度下降。
