On a BD-ROM, PlayList information is recorded. The PlayList information includes MainPath information and SubPath information. The MainPath information specifies one of a plurality of AVClips as a MainClip, and defines a primary playback section on the MainClip. The SubPath information specifies, among the rest of the AVClips, one AVClip as a SubClip, and defines, on the SubClip, a secondary playback section to be synchronized with the primary playback section. The PlayList information includes an STN_table, which indicates SubClip and, from among a plurality of elementary streams multiplexed into the SubClip, elementary streams allowed to be played back. A total data size of AVClip per unit time is, for example, less than or equal to 48 Mbits when the AVClip includes a plurality of elementary streams allowed in the STN_table to be played back and does not include elementary streams which are not allowed in the STN_table to be played back.
