    • A disk recorder (2) is provided with a RAID controller which divides one frame of source video data into a plurality of sub-blocks and, at the same time, generates parity data correlated with the sub-blocks and a CPU block which controls the RAID of the RAID controller for generating the sub-blocks from one frame. The CPU block generates a block map for theoretically formatting the recording position of each sub-block so that the recording which is performed for recording each sub-block and the reproduction which is performed for reproducing each sub-block can be performed always in a given period of time, and determines on the basis of the block map the number of division of one frame of data so that the size of each sub-block generated by means of the RAID controller can become equal to the size designated on the block map.
    • 一种磁盘记录器2具有用于将源视频数据的一帧划分成子块的多个部分并加以生成奇偶校验数据对应于子块的多个A RAID控制器,以及用于控制RAID处理用于从一帧产生的子块的多个A CPU块 RAID控制器。 CPU块基因速率为respectivement子块的理论上格式化记录位置的数据块映像,以便确实在记录在再现respectivement子块的respectivement子块和再现处理的记录处理被持续进行预定的时间周期内,和的分割确定性地雷数 数据的一帧所以没有由数据块映像指定的,所述数据块映像的基础上的RAID控制器成为大小所产生的子块respectivement的大小。
