Information recording device, information recording medium and information recording method

An non-transitory information recording medium comprising an information-recordable region onto which information is recordable,

• secondary information created by utilizing primary information whose duplication onto a different information recording medium is restricted being recorded on the information-recordable region,
• the primary information containing duplication restriction determination information indicating that duplication of the primary information onto a different information recording medium is restricted and primary identification information to identify the primary information;
• and
• the secondary information contains secondary identification information to identify the primary information utilized to create the secondary information.

An information recording method for recoding information onto an information-recordable region of an information recording medium, comprising:

• a recording step of recording, onto the information-recordable region, secondary information created by utilizing primary information whose duplication onto a different information recording medium is restricted, and
• a replay step of replaying the secondary information recorded on the information-recordable region, wherein
• the primary information containing duplication restriction determination information indicating that duplication of the primary information onto a different information recording medium is restricted,
• the information recording method further comprising a recording allow/disallow determination step of determining whether to allow or disallow recording of the secondary information onto the information-recordable region by determining the presence or absence of the duplication restriction determination information,
• the primary information include primary identification information to identify the primary information,
• the secondary information includes secondary identification information to identify the primary information utilized to create the secondary information, and
• the replay step includes determining whether to allow or disallow replaying of the secondary information by collating the primary identification information included in the primary information recorded on the information recording medium and the secondary identification information included in the secondary information recorded on the information recording medium.
