=== Compact Disc Indexes Block ('CDIX')
|
||
|
|
|
||
|
|
On CompactDisc and related media, tracks can contain multiple indexes.
|
||
|
|
These are used to mark separations in the data, such as distinct segments of a musical performance.
|
||
|
|
|
||
|
|
The table of contents always references index 1. All other indexes—including index 0 (the pregap)—are stored in the subchannel information.
|
||
|
|
|
||
|
|
This block holds a list of all known indexes for quick lookup.
