Abstract
A recording medium records a main-view stream, a sub-view stream, and management information. The management information includes a system rate for each stream, and each stream is divided into a plurality of data blocks that form a plurality of extent blocks. In each extent block, main-view data blocks and sub-view data blocks are in a continuous interleaved arrangement. A main-view data block and sub-view data block forming a single pair each have a maximum size that is determined by the following conditions: (i) the system rate of the sub-view stream, (ii) whether the pair is the top pair within the extent block, and (iii) whether a long jump region exists between the recording areas of two extent blocks that are to be read continuously.
