About blank, appendable and finalized DVD+R :
In the beginning a DVD+R holds an empty session and the Incomplete Fragment.
From these one may spawn reserved fragments or one may write directly to
the incomplete fragment. As soon as this is done the empty session becomes the
open session which finally needs to get closed. By closing fragments and
session a new empty session with empty Incomplete Fragment gets spawned.
So the disc stays appendable.
A DVD+R may hold 153 closed sessions with a single track each.
The open session may hold up to 15 open fragments. But on closure of the
session those fragments together form a single logical track. So one will
usually only use a single fragment for sequential writing.
(mmc5r03c.pdf 4.3.6.2)
The disc may get finalized by another close command so that no more data can
be written.
(mmc5r03c.pdf 6.3.3.4.4)
-------------------------------------------------------------------------------
Writing a Pseudo Session to DVD+R :
Session writing has to be pseudo because only one logical track per session
can be distinguished. So actually there have to be written multiple sessions
to mark multiple tracks. The pseudo session cannot get marked on disc and thus
the tracks of a pseudo session cannot be grouped accordingly in a TOC.
Speed can be influenced by B6h SET STREAMING , speed capabilities can be
inquired by ACh GET PERFORMANCE. It is advised to set only speeds and sizes
which are returned by ACh.
(mmc5r03c.pdf 6.39 SET STREAMING, 6.8 GET PERFORMANCE)
No mode page 05h is to be sent.
growisofs sends a page but the specs clearly state that one shall not do.
(mmc5r03c.pdf 7.5.3)
It is optional wether a track size is reserved in advance or not. Eventually
this is done by 53h RESERVE TRACK, RMZ=ARSV=0. Reservation size should better
already be aligned to 32 KiB.
(mmc5r03c.pdf 6.31)
The specs promise to pad up the track if not enough data get written.
(mmc5r03c.pdf 6.3.3.4.2)
Next Writeable Address is fetched from the reply of 52h READ TRACK INFORMATION
with track number FFh.
(mmc5r03c.pdf 6.27)
Since the fixely set write type is 16-block packet, full 32 kB buffers have
to be transmitted via 2Ah WRITE.
(mmc5r03c.pdf 4.3.6.2.2)
When writing is done, it is mandatory to force the drive's buffer to media by
35h SYNCHRONIZE CACHE.
(mmc5r03c.pdf 6.41)
The written fragment (i.e. track-to-be) has to be closed by 5Bh CLOSE TRACK
SESSION Close Function 001b.
(mmc5r03c.pdf 6.3.3.4.2)
libburn obtains the necessary logical track number from Last Track Number in
Last Session from the reply of 51h READ DISC INFORMATION requesting
Data Type 000b.
(mmc5r03c.pdf 6.22)
After each track 5Bh CLOSE TRACK SESSION Close Function 010b with Logical Track
Number 0 closes the DVD+R session but keeps the media appendable.
(mmc5r03c.pdf 6.3.3.4.3)
Eventually 5Bh CLOSE TRACK SESSION Close Function 101b is used to finalize
the media with minimal radius. After that the disc is not appendable any more !
