There is provided with a data cleaning program capable of deleting data recorded in a data recording medium so as not to be restored. Further, there is provided with a data cleaning program capable of making it impossible to read unnecessary data remaining in a data recording medium. A part of an operating system 14 required for a cleaning operation and/or a data cleaning program 22 are saved into a main memory 3, so that the part of the operating system 14 and/or the program 22, both saved, write predetermined data over a recording area of a file specified to be cleaned. All addresses of recording areas 14a of a FAT in which release codes are recorded are extracted, so that clusters 17a in the data area 17 corresponding to the extracted addresses are written over with desired dummy data.
