1. A visible image forming method for forming a visible image on an optical disk by an optical disk recording apparatus, which is designed for applying a laser beam onto an optical disk according to first recording data of a predetermined format to form pits having lengths specified by the first recording data, the method comprising:
a generating step for generating second recording data by embedding image formation data of a visible image in a part of a predetermined format which is the same as predetermined for the first recording data;
an extracting step for extracting the image formation data of the visible image from the second recording data of the predetermined format; and
a forming step for forming pits in the optical disk according to the extracted image formation data so as to form the visible image on the optical disk.
