The COPY/RECORDABLE_MEDIA (CDDVD) Utility allows users to create
Compact Disk (CD) and Digital Versatile Disk (DVD) media directly
on OpenVMS, using an optional optical disk recorder.
CDDVD generates ISO/IEC 10149 Mode 1 (2048-byte blocks, data)
single-session optical media recordings. CDDVD supports the
recording of various optical media formats, including CD
Recordable (CD-R), CD Rewritable (CD-RW), DVD Recordable (DVD+R)
and DVD Rewritable (DVD+RW) formats. For a successful recording
operation, one or more of these formats must be available within
the target optical disk recording device. Compatible recording
media must also be loaded into the recording device.
The COPY/RECORDABLE_MEDIA command opens the specified input disk
image file or input master device and records the entire contents
to the specified CD-R, CD-RW, DVD+R, and DVD+RW media formats.
Format
COPY/RECORDABLE_MEDIA source-path-name target-path-name
1 – Parameters
input-filespec
Specifies the name of an existing file (the source file) to be
copied.
source-path-name
This is the data source for the recording operation.
Specify the name of a disk file containing a disk image to be
copied onto the target recording media, or the device name of the
input device containing the disk volume master for the recording.
On OpenVMS systems, this is usually a Logical Disk (LD) Utility
LDAu: device.
target-device-name
The device name of the target recordable media device.
This is usually the name of an ATAPI (DQcu:) SCSI (DKcu:), or USB
(DNcu:): CD-R/RW or DVD+R/RW recording device, or both.
2 – Qualifiers
2.1 /BELL
Sounds an audible signal when the requested recording operation
completes successfully.
2.2 /FORMAT
/FORMAT[=keyword]
/NOFORMAT (default)
Requests that rewritable (RW) media be formatted or reformatted
prior to use. This qualifier is required for writing to blank
rewritable media or rewriting rewritable media.
If the target media cannot be formatted, this command qualifier
is ignored.
If not specified, the appropriate keyword is automatically
selected for the fastest formatting speed available for the
target recording media.
Keywords for the /FORMAT Qualifier lists available keywords.
Keyword Description
WAIT Applies to DVD+RW. The default for the /FORMAT
qualifier is not to wait for the formatting to
complete because waiting is usually unnecessary and
far slower.
Selecting WAIT causes the entire format to run
synchronously to completion before beginning the
recording operation.
The default is to:
o Operate asynchronously
o Perform background formatting
o Run both the media format operation and the
recording operations concurrently
ERASE Applies to CD-RW.
The default for the /FORMAT qualifier is to perform a
quick erasure because a full erasure is usually both
unnecessary and far slower.
Selecting ERASE causes the CD-RW rewritable disk to
be entirely erased as part of the format operation.
This erasure is performed and is completed before the
recording operation begins.
The default is to perform a quick erasure.
2.3 /LOG
/LOG (default)
/NOLOG
Shows basic device information and the progress of the recording
operation. Use /NOLOG to disable the normal output from the
utility.
2.4 /SPEED
If you must use the lower-speed or poor-quality CD recording
media, the /SPEED qualifier is often required for successful
completion of the recording process. You might need to select a
recording speed below the rated speed of the CD drive itself.
Specifically, you might need to select a recording speed that
is compatible with both the CD drive and the CD recording media
loaded in the drive.
The /SPEED qualifier accepts a single keyword for a requested
device speed:
o 1X
o 2X
o 4X
o 8X
o 16X
o 32X
o MAXIMUM
The CDDVD utility attempts to match the requested speed to a
speed that the device supports. (Not all devices support all
speeds, including the lowest speed, 1X, or the highest speed
available.) The default speed is the maximum speed that the
target device supports. DVD+R/RW drives select the maximum
recording speed based on information encoded on the media.
You need to specify this qualifier only under one of the
following circumstances:
o When incompatibilities or recording errors are reported during
a previous failed recording operation.
o If the CD media in use has a rated recording speed below the
drive default recording settings.
o If CDDVD application, processor, or system I/O performan
constraints exist.
CD drives can select speeds faster than those supported by the
particular media loaded in the drive. VSI recommends that you
select only media that match the recording capabilities of the
drive. In other words, do not attempt to exceed the recording
speed limits of the particular CD media. Selecting faster media
will not make a slow drive record any faster, and selecting
faster speeds with slow media can trigger recording errors and
corrupt media.
If the recording process fails during the recording operation,
discard the write-once media and try a slower recording speed.
(Note that you can attempt to reformat and rerecord on rewritable
media.)
2.5 /VERIFY
Specifies that the contents of the output media be compared to
the contents of the input source after the recording operation.
Any data comparison errors detected are displayed.
2.6 /WRITE
/WRITE (default)
/NOWRITE
Allows you to test the system and device I/O throughput and the
command syntax without recording on the target media.
If you specify /NOWRITE and if the target drive supports the
underlying test-write hardware capability, all I/O operates as
usual although /NOWRITE disables writing to the media.
/WRITE is the default, and causes the target optical media to be
written.
