A recording medium according to the present invention includes: a recording-medium supply mechanism; a single-sheet supply mechanism for supplying a recording medium S one sheet by another from a hold device to a conveyance path; and an overlap supply mechanism for supplying a desired number of sheets of a recording medium from the hold device in an overlapped state to the conveyance path. If there is one sheet or more of consecutive blank pages included in a recording medium to be supplied to the conveyance path, the recording apparatus overlaps and supplies a recording medium as many sheets as a value obtained by adding one to a number of the blank pages, to record recording data of a page immediately preceding or following the blank page.
