Abstract
A recording apparatus for an SD memory card that has a plurality of EPUBxxx.KEY files recorded thereon, each file having a plurality of Key&Rule Entry areas, and an SD_EPUB.MMG file being read from the recording medium prior to the writing of data. A bitmap in SD_EPUB.MMG shows for each EPUBxxx.KEY file whether the EPUBxxx.KEY file has at least one Key&Rule Entry area not in use, or whether all the Key&Rule Entry areas are in use. Based on the bitmap in the read SD_EPUB.MMG file, the recording apparatus opens EPUB#u.KEY having an unused Key&Rule Entry area and writes data into the unused Key&Rule Entry area in the file. If all the Key&Rule Entry areas in EPUB#u.KEY become in use as a result of the writing of the data, the recording apparatus updates the bitmap in SD_EPUB.MMG.
