    摘要: A recording medium stores contents and contents keys to be used for encrypting the contents, in a plurality of storage formats. The storage formats include a storage format (a first format) for delivered contents acquired through a network, and a storage format (a second format) for local contents acquired by a method other than the delivery. The intrinsic storage formats of the contents to be stored in the recording medium are determined according to the kinds of the contents. The recording medium stores not only the contents and the contents keys but also original storage format information (an import flag) (851) which is information indicating the intrinsic storage formats of the contents. With reference to the original storage format information, a reproduction device selects a reproduction method in accordance with the intrinsic storage formats of the contents.

    摘要: Provided is a method for performing high-speed search for a content key associated with encrypted content in the case of a key-separation-type content management method where content keys and their respective pieces of encrypted content are correlated by ID information and stored in different recording media. An external recording medium is used to store a plurality of content files that contain: their respective pieces of encrypted content that are encrypted with different encryption keys; and their respective content IDs, each being associated with a corresponding piece of the encryption content, and a semiconductor recording medium is used to store a list that contains: pieces of encryption key storage location information, each indicating where a corresponding one of the encryption keys is stored; and the content IDs, the list being sorted in accordance with the content IDs. When encrypted content is played back, the list is searched to find encryption key storage location information associated with a content ID that matches the content ID of the encrypted content, and the encryption key is read based on the encryption key storage location information.

    摘要: An information recording medium includes a data storage section having a plurality of recording regions for storing data, and a region information storing section operable to store information about each recording region in the data storage section. The region information storing section stores information about a recording region (for example, a recording region has been accessed finally) which is set first as an accessible region when the information recording medium is initialized at the next time among a plurality of recording regions in the data storage section. A data processing apparatus refers to the information about the recording region and changes over a recording region to the recording region specified by the information about the recording region just after initialization of the recording medium.
