Hello Katata-san,

Thank you very much for your comments on my questions. Almost all of my
questions become clear. But I would like to confirm one thing.


><Ans2>
>Reduced Border-out with SMA will be allocated at NWA.

I understand this answer means that the drive MUST move the location of
SMA to the inner part of the disc upon finalizing even if the SMA has
already specified as follows.

   <-  LO  ->                                               <--- MA --->
L1 LLLLLLLLLL######-----------------------------------------------------
L0 LLLLLLLL########-----------------------------------------------------
   <- LI ->        ^                  ^
                  NWA           Specified SMA
                                start address

      | Finalization
      v

   <-  LO  ->      <- SMA ->                                <--- MA --->
L1 LLLLLLLLLL######BBMMMMMMM--------------------------------------------
L0 LLLLLLLL########BBMMMMMMM--------------------------------------------
   <- LI ->        ^                  ^
               SMA start        Specified SMA
                address         start address

    where L:Lead-in or Lead-out
          #:Recorded portion
          M:Shifted Middle area
          B:Border-out or Superficial Border-out
          -:Unrecorded portion


Does this a mandatory function or optional? Is it allowed to record the
SMA at the requested location and pad the area between the NWA and the
SMA by all zero data?

   <-  LO  ->                         <- SMA ->             <--- MA --->
L1 LLLLLLLLLL######PPPPPPPPPPPPPPPPPPPBBMMMMMMM-------------------------
L0 LLLLLLLL########PPPPPPPPPPPPPPPPPPPBBMMMMMMM-------------------------
   <- LI ->        ^                  ^
                  NWA           Specified SMA
                                start address
