DVD-RW are usable if formatted to state "Restricted Overwrite" or if in state
|

"Sequential Recording" - provided the "Incremental Streaming" feature (21h) is
|

available.
|

|

"Sequential" is the state of unused media and of media previously blanked
|
||||
or written by cdrecord. dvd+rw-format -blank can also achieve this state.
|
||||
(Command dvd+rw-format -force can achieve "Restricted Overwrite".)
|
||||
|
||||
The according cdrskin option is blank=deformat_sequential .
|
||||
If "Incremental Streaming" is available, then sequential media are capable
|
||||
of multi-session like CD-RW. (But not capable of -audio recording.)
|
||||
This means they need option -multi to stay appendable, need to be blanked
|
||||
to be writeable from start, return useable info with -toc and -msinfo,
|
||||
eventually perform appending automatically.
|
||||
Without "Incremental Streaming" offered by the drive, they are regarded as
|
||||
unsuitable media for now.
|
||||
|
||||
Overwriteable DVD behave much like DVD+RW. "Restricted" refers only to the
|
||||
granularity of random access and block size which have always to be aligned to

||||

|

(Command dvd+rw-format -force can achieve "Restricted Overwrite", too.)
|
||||
|
||||
Formatting or first use of freshly formatted DVD-RW can produce unusual noises
|
||||
from the drive and last several minutes. Depending on mutual compatibility of
|
||||
drive and media, formatting can yield unusable media. It seems that those die

||||
too on blanking by cdrecord or dvd+rw-format. Perils of DVD-RW, i fear.

addressable by cdrskin. DVD-ROM drives might show ill behavior with them.
|

blank=format_overwrite_full uses preferrably "Full Format" (type 00h).
|
||||
This formatting lasts as long as writing a full DVD. It includes writing of
|
||||
lead-out which is said to be good for DVD ROM compatibility.
|

|

A de-formatting option is available to make overwriteable DVD-RW sequential:
|
||||
|

blank=deformat_sequential performs thorough blanking of all states of DVD-RW.
|
||||
|
||||
blank=all and blank=fast perform the same thorough blanking, but refuse to do
|
||||
this with overwriteable DVD-RW, thus preserving their formatting. The specs
|
||||
allow minimal blanking but the resulting media on my drives offer no
|
||||
Incremental Streaming afterwards. So even blank=fast will do full blanking.
|
||||
|
||||
|
||||
DVD-R
|
||||
|
||||
The specs state that DVD-R behave like sequential DVD-RW except the capability
|
||||
to get blanked or formatted. Thus they should be useable like CD-R media (but
|
||||
without -audio).
|
||||
Blank DVD-R media are accepted as suitable by cdrskin on my drives.
|
||||
I got only a few of those one-time recordable media and no real use case.
|
||||
So i prefer to start burning my DVD-R only at the end of my endeavor about
|
||||
sequential DVD. There's still plenty to do with DVD-RW testing.
