Abstract:
An information processing apparatus comprising:control means for allowing a physical position of file data which is recorded on a write-once medium to correspond to a logical position, generating a correspondence table between the logical position and the physical position thereby controlling, upon the physical position being changed, the correspondence relation between the logical position and the physical position after the change;recording means for recording the file data in a memory and element data of the correspondence table to the write-once medium as written data;calculating means for calculating a writable residual capacity of the medium based on a whole recordable capacity recorded on the write-once medium and a recordable residual capacity from a last physical position which is currently recorded on the write-once medium;comparing means for comparing an amount of the written data in the memory with the writable residual capacity of the medium to determine a surplus; andoutputting means for outputting a surplus detection result when the surplus is detected,wherein the recording means records the written data in the memory on the write-once medium when the surplus detection result is output.
