Abstract

PURPOSE: To improve the use efficiency of a medium by determining the number of physical sectors to reproduce actually with a control means by the address of the physical block to reproduce by an address converting part.
CONSTITUTION: An address converting part 2 to convert a recording reproducing instruction by a logical block address from a file control part 1 to a recording reproducing instruction for the corresponding physical sector is provided. For the instruction from the file control part 1 to control data in the logical block unit of a constant size, the number of the physical sectors to reproduce by the address of the logical block is determined by the address converting part 2. Consequently, without limitation by the logical block size, only the necessary physical sector part can be recorded and reproduced by matching to the information quantity to be recorded. Thus, the memory medium can be used wastelessly and efficiently.
