Abstract
Number data affixed to individual digital data divided into a plurality of data blocks are sequentially read out from a recording medium to be used for determining the write-in positions of the digital data in a memory. For determining the write-in positions of the digital data, the number data of the next write-in position is estimated on the basis of the number data of the current write-in position. Judgment is made as to whether or not the number of times of continuous non-coincidence between the estimated number data and the successively read-out number data exceeds a predetermined setting, and, also judgment is made as to whether or not the number data read out each time falls within a predetermined range. Depending on the results of these judgments, one of the read-out number data and the estimated number data is selected to determine the next write-in position.
