Description

Like any drive, discs may store their data according to many different filesystem structures. These are abstracted to a degree in libcdio, but as each track may store its data differently, and at the very least Audio is handled differently than any of the file-oriented layouts, it is still helpful to know the underlying structure. This module, then, is a counterpart to Sound.Libcdio.Read.Data, providing information about the structure for the latter's retrieval of data.
