    • A data recording/reproducing apparatus comprises a data recording/reproducing component for recording data including audio and/or video data in and reproducing such data from a plurality of non-linearly accessible recording medium, a plurality of input/output processing sections for processing the input data and outputting them to the recording/reproducing component, while processing the data output from the recording/reproducing component and outputting them, a controller for controlling the input/output processing sections so as to make them carry out the processing operations in the allocated respective time slots and outputting time slot signals with a fixed cycle period to the respective input/output processing sections, the controller being so adapted that, when there is an idle input/output processing section out of the plurality of input/output processing sections, it outputs the time slot signals to be output to the idle input/output processing section to the remaining input/output processing section. With such an arrangement, more time slots are allocated to the busy input/output processing sections, which can therefore output an increased number of data sheets per unit time for a high speed data reproducing operation to improve the operability of the apparatus.
    • 数据记录/再现装置包括用于将包括音频和/或视频数据的数据记录在多个非线性可访问记录介质中并从其再现的数据记录/再现部件,多个输入/输出处理部分,用于处理 输入数据并将其输出到记录/再现部件,同时处理从记录/再现部件输出的数据并将其输出;控制器,用于控制输入/输出处理部分,以使其执行分配的处理操作 相应的时隙并且将固定周期的时隙信号输出到相应的输入/输出处理部分,所述控制器适于当多个输入/输出处理部分中存在空闲输入/输出处理部分时, 它将要输出到空闲输入/输出处理部分的时隙信号输出到剩余的输入/ o 输出处理部分。 通过这种安排,更多的时隙被分配给繁忙的输入/输出处理部分,因此可以输出每单位时间内增加数量的数据表以进行高速数据再现操作,以提高装置的可操作性。
