摘要

Audio information is stored on a unitary storage medium with a Table-of-Contents (TOC) mechanism for therein specifying an actual configuration of various audio items on the medium. In particular, one or more Sub-TOCs are each assigned to a respective different audio format. A single Master-TOC is provided for specifically pointing to each Sub-TOC.
