Abstract

In a computer system having a recording/ reproducing device in which a DVD-RAM or the like is used as a recording medium, the CPU and the memory allocates logical blocks and record blocks, in multiple units of a common block for data to be written on a recording medium. The common blocks have a size of the least common multiple of the size of logic block and the size of record block, and the front of the allocated logical blocks coincides with the front of the allocated record blocks. The data is recorded on the recording medium by the recording/reproducing device. Hence, the data can be recorded in the most desirable manner even if the logical blocks and the record blocks defer in size.
