Two Methods
There are two methods for copying data from CD to recordable disc:
- Copy a track directly from a disc in a CD-ROM drive or a
second CD recorder to a recordable disc in your primary CD
recorder.
- Copy a track from a disc in your CD recorder to hard disk, using
the Read function.
- This track can then be written to recordable
CD using either the "File" option in the Write Source dialog box
(for single audio tracks or ISO 9660 images), or through the
Cue Sheet function (for audio or mixed-mode discs).
Which method you can use will depend on the capabilities of your
system, as explained below.
Disc-to-Disc Copying
Source Formats and Devices
- Any ISO 9660 Mode 1 track can be copied.
- Copying CD-DA audio is supported only when you use as your source drive a CD recorder which supports reading audio
tracks in digital format.
With MM
If Mode 1 is set in the CD-Image menu, the Write Source dialog box will show only devices containing Mode 1 data.
- If Mode 2 is set in the CD-Image menu, the Write Source dialog box will show only devices containing Mode 2 data.
- Macintosh HFS CD-ROMs can be copied using the"SCSI Device" option in the Write Source dialog box.
Device Speeds
Whether you can copy data directly from CD to CD also depends on the
relative speeds of your CD-ROM drive and CD recorder. In most cases
you will have to write at 1x speed. Always Test first to see whether
adequate throughput can be sustained.
If your source device is not fast enough to support the throughput
required by your CD recorder, you must first copy the track and save it
as a file on hard disk (see the section below on the Read function).
Procedure
- Click on the Toolbar or select Write from the CD-
Recorder menu. The Write Source dialog box appears.
- Select "SCSI Device;" you see a list of all the SCSI devices
connected to your computer.
The numbers in parentheses represent:
- the SCSI interface card ID number.
- the SCSI device ID number.
- the SCSI device Logical Unit Number (LUN).
- Select the source to write from. A dialog box opens.
The name of the source device and the name (if any) of the
source CD are reported.
If the source is an ISO 9660 image, the
program will recognize it, and the starting address and length
should be given correctly. Click OK.
- The Write dialog box opens.
- The Mode should be set correctly by default; if not, correct it.
- Select the "1x" writing speed.
- If you wish after writing to verify that the data has been
correctly copied, select "Verify Data."
- Click on Test.
- In the succeeding dialog box, click on Start to begin the test.
- If the Test is successfully completed, proceed with writing by
clicking on Write.
Again, you will see a dialog box with a Start
button to click.
Please ensure that you are not violating international law by copying
material which is under someone else's copyright.
The Read Function
Read from the CD-Recorder menu
Keys: ALT + R, R
The Read function can be used to copy entire Mode 1, Mode 2, and
audio CD tracks to hard disk from your CD recorder. However, the types
of tracks you can read (and the appearance of the Read dialog box)
depend on your CD recorder. (For each recorder, the Read dialog box looks
almost exactly like the Medium Info dialog box, and provides the same
information about the disc in the CD recorder; the only difference is the
addition of the Copy Track button.)
- In the Table of Contents area, select the track you want to copy
to hard disk. Click on Copy Track.
- A dialog box appears proposing the starting address and length
(in blocks) of the highlighted track.
These can be changed if
necessary, but generally you should accept the defaults given to
copy the entire track correctly. Click on OK.
- The Save to...dialog box appears, in which you may specify the
path and name in which to save the track being copied.
If there is not enough space on the target drive to save the track, you
will be warned and nothing will be copied.
- Message: "Last Two Blocks Stripped..."
If the track you are copying is from a multisession disc, at the
end of reading you will see the message
"Last two blocks
stripped (Orange Book link)."
This is because a multisession
track is always followed by two run-out blocks. These are
included in the count of the total size (in blocks) of the track,
but they do not contain data and cannot be read back. This
message appears to alert you just in case you notice that you
copied two blocks fewer than were reported in the read length
dialog box, but don't panic - you have not lost any data!
