ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to the field of is the well-known with digital audio encoding is the well-known Compact Disc system. Progress in storage technology and audio encoding technology allows increasing amount of audio information on a unitary medium such as conforming to the standard CD dimensions. A particular feature is variable-rate encoding, which requires an easy accessible indicator organization for subsequent read-accessing of the string of Audio Units.

SUMMARY OF THE INVENTION
It is an object of the present invention to allow a reader device to straightforwardly recover all information pertaining to an Audio Unit that may have been dispersed over various storage blocks or sectors.
The invention also relates to a unitary storage medium produced by practising such method, and to a reader device for reading a unitary storage medium so produced.
