Interleaved files are defined between <FileInterleaveFile line> and
<EndFileInterleaveFile line>. Information for the interleave (unit size and gap
size) is specified in the
FileInterleave parameters. Unit sizes and gap sizes differ
depending on the files interleaved. A single file that is not interleaved is selected
between <FileInterleaveFile line> and <EndFileInterleaveFile line>.
Defining Files
Files are defined between a <File line> and an <EndFile line>. The ISO9660 file
name is specified per
<File line> parameter. The actual file contents are specified as
file source, MPEG file, or channel interleave file. Multiple files can be specified if
they are of the same type. When an ISO9660 file uses one data file as the input
source, only
<File line> and <EndFile line> need to be used to specify file names
if the names are the same.
File definition uses the following lines:
• BeginTimeS (simple files, channel-interleaved files)
Specifies the starting position of the disc location where the file is placed as the relative position
within a session. When the specified area overlaps another file, a warning message is displayed.
If this line is not specified—that is, no time is specified—the disk image is created in order and
placed after the final sector on the disk image where the file definition script is described.
• EndTimeS (simple files, channel-interleaved files)
Specifies the ending position of the area within the disc where the file is placed as the relative
position within a session. When the specified area overlaps another file, a warning message is
displayed. If this line is not specified, the default placement is the same as the specified
BeginTimeS value or the BeginTimeS default value.
• Attributes (simple file, channel-interleaved files)
Specifies the file attributes. The following are the attributes:
HIDDEN/NOHIDDEN
RECORD/NOTRECORD
Set one attribute from the pair to the parameter. When this line is not specified,
NOHIDDEN∆NOTRECORD becomes the default.
• RecordingDate (simple file, channel-interleaved files)
Specifies the file recording date. When this line is not specified, the date of CD image creation is
used.
• MinLength (simple file, channel-interleaved files)
Specifies the minimum number of bytes for the file area. Regardless of the actual size of the file,
the disk-area size specified by this line is reserved as the minimum for this file. It can be
set so that file and track positions remain unchanged even when the file is updated later and its
size increased as a result.
• Trigger (simple file, channel-interleaved files)
Specifies the length of time that the trigger is applied in relative time from the start of the file.
• Eors (simple file, channel-interleaved files)
Specifies the length of time that the EOR (End Of Record) is applied in relativetime from the start
of the file. The line is effective only on files with MODE2 tracks.
• Pack (File interleave file, channel interleave file)
In file interleave and channel interleave, the remainder of long files are packed into short files.
