Abstract

Information recording medium (1) comprises recording area (13) capable of recording contents and information area (12), this information area provided with control information section (122) capable of recording control information for controlling of regeneration of the contents recorded in the recording area and key information section (121) in which at least encrypted first key information resulting from encryption of first key information for regeneration of the recorded contents and second key information being part of decryption information for decryption of the encrypted first key information are recorded in advance. The state of recording of contents recorded in the information recording medium can be ensured by at the final stage of the recording, decrypting the encrypted first key information and recording the same in the control information section.
