Abstract
A recording medium is formed of a plurality of flash memories. A recording medium controller manages the recording status of the plurality of flash memories in units of blocks. The recording medium controller controls a data recording process so that data is recorded in such a manner that one or more parallel block sets are constructed which consist of one or more blocks the number of which is determined in accordance with a minimum number of blocks required to obtain a minimum waiting time in the process of recording data in a parallel fashion into the one or more blocks of the recording medium, and the data is recorded in the parallel fashion in the one or more blocks of the one or more parallel block sets, thereby recording data on the recording medium at a high speed. The recording medium controller also controls the data recording process so that data is recorded in such a manner that one or more parallel block sets each consisting of one or more blocks used to record the data are constructed in such a manner as not to create a significant difference in the size of a writable area available for recording data among the plurality of flash memories, and the data is recorded in the parallel fashion in the one or more blocks of the one or more parallel block sets, thereby recording data on the recording medium without creating a significant difference in the writable area size.
