A data recording device that records content data onto a recordable disc, the data recording device comprising: a selecting unit operable to receive a selection of content data; an obtaining unit (1202, 1203) operable to obtain physical and logical characteristics of a disc that has been inserted in the data recording device; a judging unit operable to judge, whether or not the disc is a predetermined recordable-type disc based on the obtained physical and logical characteristics, the judging unit judges that the disc is the predetermined recordable-type disc when: a physical characteristic of the disc satisfies one or more of conditions that (i) neither land nor groove is present, (ii) a recording layer is not present in an area inward of a lead-in area, (iii) groove wobble amplitude is 0, and (iv) groove wobble frequency is not 140.645 kHz, and a logical characteristic of the disc satisfies one or more of conditions that (i) an area storing R/RW physical format information for a DVD-R disc is embedded with a value which is different from a value which indicates a DVD-R, (ii) physical format information indicates the disc is a ROM disc and (iii) content provider information is recorded in the lead-in area; a charging unit operable to perform a charging process for a payment amount of the selected content data when the judging unit judges affirmatively, and a writing unit operable to write the content data onto the disc after the charging process is completed by the charging unit, when the judging unit judges affirmatively. a selecting unit operable to receive a selection of content data; an obtaining unit (1202, 1203) operable to obtain physical and logical characteristics of a disc that has been inserted in the data recording device; a judging unit operable to judge, whether or not the disc is a predetermined recordable-type disc based on the obtained physical and logical characteristics, the judging unit judges that the disc is the predetermined recordable-type disc when: a physical characteristic of the disc satisfies one or more of conditions that (i) neither land nor groove is present, (ii) a recording layer is not present in an area inward of a lead-in area, (iii) groove wobble amplitude is 0, and (iv) groove wobble frequency is not 140.645 kHz, and a logical characteristic of the disc satisfies one or more of conditions that (i) an area storing R/RW physical format information for a DVD-R disc is embedded with a value which is different from a value which indicates a DVD-R, (ii) physical format information indicates the disc is a ROM disc and (iii) content provider information is recorded in the lead-in area; a charging unit operable to perform a charging process for a payment amount of the selected content data when the judging unit judges affirmatively, and a writing unit operable to write the content data onto the disc after the charging process is completed by the charging unit, when the judging unit judges affirmatively. a physical characteristic of the disc satisfies one or more of conditions that (i) neither land nor groove is present, (ii) a recording layer is not present in an area inward of a lead-in area, (iii) groove wobble amplitude is 0, and (iv) groove wobble frequency is not 140.645 kHz, and a logical characteristic of the disc satisfies one or more of conditions that (i) an area storing R/RW physical format information for a DVD-R disc is embedded with a value which is different from a value which indicates a DVD-R, (ii) physical format information indicates the disc is a ROM disc and (iii) content provider information is recorded in the lead-in area; a charging unit operable to perform a charging process for a payment amount of the selected content data when the judging unit judges affirmatively, and a writing unit operable to write the content data onto the disc after the charging process is completed by the charging unit, when the judging unit judges affirmatively.
