• Channels

This line is used to specify whether the track will have two channels or four. This line is valid only

with CDDA track types. The instruction is reflected in the Q subcode data. If this line is not

specified, the default is 2.

• Copy

This line is used to specify the copy-protection status of the audio data of a given track type. If the

parameter value is TRUE, digital copying is permitted. If this line is not specified for tracks that

require specification, the default is FALSE.

• Directory Definition

Defines the CDDA track as the final track. Directories can be used to give data tracks a

hierarchical structure using directories.

Directory Definition

Directories are defined between <Directory line> and <EndDirectory line>. Each

group from

<Directory line> to <EndDirectory line> represents a single directory.

A hierarchical directory structure can be defined by placing sets of

and <EndDirectory line> within the outer set of <Directory line> and <EndDirectory

line>. The Directory line parameter specifies the directory name.

Directory files can be of two types:

• Interleaved files.

• Non-interleaved files.

There are three types of non-file interleaved files:

• Simple files

• Files that are channel-interleaved files.

• MPEG files

Interleaved files are created from files that are non-interleaved.

The following lines specify the characteristics of the directory itself:

• Attributes

Specifies the directory attributes with a parameter. An attribute may be either HIDDEN or NOHIDDEN.

If this line is not specified, the default is NOHIDDEN.

• MinLength

Specifies the minimum number of bytes for the directory.

• RecordingDate

Specifies the directory recording date. If this line is not specified, the CD image creation date is used.

Defining Interleave Files

Interleaved files are defined between <Extent line> and <EndExtent line>. Specify

the interleaved file disk location by using the relative location within the session per

the

Extent line parameter. When the specified area overlaps another file, a warning

message is displayed and processing stops. If this parameter specification is omitted

(that is, no relative position is specified), a warning message is displayed.
