    摘要: When packeting content data and recording the packeted content data to a recording medium having a plurality of sectors made up of at least a header and packet data, if a remaining data length of the last sector of the plurality of sectors to which the packeted content data is recorded is smaller than the data length of the header, supplementary data equivalent to the remaining data length of the last sector is generated and the generated supplementary data is added to the content data so as to packet and record the content data with the supplementary data added thereto.

    摘要: Data areas AR1 and AR2, lead-in areas LIN1 and LIN2, and lead-out areas LOUT1 and LOUT2 are provided on a disc. For example, in case of encrypting and recording data into the data area AR2, copyright management information R2 and key information K2 are recorded into the lead-out area LOUT2. Only information in a Q channel of a subcode is recorded in the lead-out area and this area is filled with dummy data. A position of the lead-out is obtained from TOC information. The fact that a light spot has entered the lead-out area can be judged from the information in the Q channel. The copyright management information and key information are recorded by using the lead-out area. The lead-out area is not rewritten or accessed by an ordinary CD player, so that the copyright management information and the key information can be safely held.
