It provides a memory card and the memory card recording and reproducing apparatus which can prevent the maker deny that they store the same media ID to each memory card. The memory card 100 is provided with a media storage module ID section 610 and a memory unit 120. Media ID storage module 610 is a proof section 609 to generate the authentication information to the basis of the media ID storage unit 611 that stores the media ID unique to the memory card, the media ID to prove his legitimacy It includes. The memory unit 120 is provided with the encrypted content storage unit 122 for storing the encrypted digital content. The recording and reproducing device 200 acquires the authentication information from the memory card 100, and on the basis of the authentication information acquired verify the validity of the memory card 100, if it fails to verify the decryption of the encrypted content or content and a memory card verification section 211 to prohibit the encrypted, if the verification is successful and a content decryption unit 209 to encrypt the digital content, or decrypts the encrypted digital content.
