摘要： As an information recording medium, an optical disc such as a DVD-R and the like, is applicable. The optical disc has a recording structure which includes a lead-in area, a lead-out area and a user data area. The lead-in area includes control information area having control information data, such as an address of recording data. Moreover, the control information area includes a predetermined remaining quantity area. Until recorded control information data does not reach the predetermined remaining quantity area, when the data is recorded on the optical disc, the newest control information data is additionally recorded in the control information area every time the optical disc is ejected. On the other hand, after the control information data reaches the predetermined remaining quantity area, the newest control information data is additionally recorded in the control information area only when additional recording data larger than a predetermined quantity is recorded. Therefore, the consumption of recording capacity of the control information area can be suppressed, and the newest information can be immediately obtained when the recording medium is inserted.

摘要： As information recording medium, an optical disc, such as a BD-R and the like, is applicable. The optical disc has a recording structure including a lead-in area, a lead-out area and a user data area. In addition, the optical disc is adopted to a defect management system, and a spare area and a defect management area are provided between the user data area and the lead-out area. When recording capacity of the space area becomes insufficient, the spare area is expanded. At the same time, the defect management area is also expanded. Thus, it is possible to cope with the increase of the defect management information due to the increase of the spare area.

摘要： The terminal device is configured to be able to reproduce and record contents, and performs reproduction and recording of an optical disc of high recording density, such as a BD. The offer information receiving unit receives the offer information, indicating a condition for performing the managed copy defined by the AACS, from the managed copy server. The offer information transmitting unit transmits the offer information to the server device in order to register the offer information with the server device. By this, the offer information of plural contents can be managed by the server device, and plural users can appropriately share the offer information. Therefore, it becomes possible to know the offer information of a disc, in advance, without actually buying the disc.

摘要： A temporary defect management area 14 is placed between a control information recording area 12 and a data area 11. Before a recording medium 10 is finalized, defect management information is temporarily recorded into the temporary defect management area. Upon finalizing, the defect management information is recorded into a definite defect management area 13 placed in the control information recording area.
