Hi David,
Blank C/DVD-RW disc
(Lead-in)_____________________________(Lead-out)
A session is recorded. "==" is written Lead-out.
 Lead-in ++++++++++++++++++++==_______(Lead-out)
Minimally Blanked disc.
 Lead-in ++++++++++++++++++++==_______(Lead-out)
You wrote new track "**" on it.
 Lead-in ********++++++++++++==_______(Lead-out)
Eject/Load, drive cannot see difference between * & +.
So disc has a type of recorded area "++".
 Lead-in ++++++++++++++++++++==_______(Lead-out)
So MMC allows Session at Once recording on the Minimally Blanked disc. DVD-RW
does not have SAO, then only DAO is possible.
Best regards,

Dear Katata-san,
I did not understand the relation between NWA after quick blank and
load/eject.
Could you clarify again and maybe give examples?
Best regards,
David Burg.

It is because that drive cannot see where is recorded after quick blank or
where
is recorded before quick blank. So host software cannot get the true Next
Writable Address that the software made before ejecting/loading the disc.
And the sequential recording mode of DVD-RW is prepared for DVD-R application
development. Software venders can perform automatic cyclic test of DVD-R
application using DVD-RW full blank.
It is not recommended to use the sequential recording mode of DVD-RW for the
DVD-RW product. Rigid redistricted overwrite is the native mode of DVD-RW.
