+- SRM Formatting
+- Writing a session in SRM-POW
+(- Pseudo-OverWrite SRM+POW)
+
+
+-------------------------------------------------------------------------------
+SRM Formatting:
+
+Despite being write-once media BD-R can optionally carry some formatting.
+
+SRM has a disc structure model with tracks and sessions.
+Several tracks may be open at the same time, each having its own NWA.
+(mmc5r03c.pdf 4.5.3.5.2.2)
+This structure is formatted onto blank media automatically as soon as the
+first serious write attempt occurs.
+(mmc5r03c.pdf 4.5.3.5)
+Before such a write attempt, blank media may be explicitely formatted with
+spares, which provide defect management.
+(mmc5r03c.pdf 4.5.3.5.3)
+Tracks get created from other tracks via RESERVE TRACK splitting.
+(mmc5r03c.pdf 4.5.3.5.2.5)
+
+On top of defect management there may be Pseudo-OverWrite SRM+POW, a costly
+way to write several times to the same LBA. See below.
+Fully sequential states are called SRM-POW.
+(mmc5r03c.pdf 4.5.3.5.4)
+
+Explicite formatting is done by 04h FORMAT UNIT. Its data payload consists
+of a Format List Header and a Format Descriptor. It is advisable to set
+the Immed bit and the FOV bit in header byte number 1. The descriptor should
+be a copy of a descriptor from 23h READ FORMAT CAPACITIES but the size may be
+adjusted within a certain range.
+(mmc5r03c.pdf 6.5, 6.5.3.2, 6.5.3.3)
+
+Format type 00h creates SRM layouts with a default number of spares (or
+eventually RRM) chosen by the format sub-type:
+  00b = SRM with support for POW
+  01b = SRM without POW (but with some spares for defect management)
+  10b = (RRM)
+(mmc5r03c.pdf 6.5.4.2.1.6)
+
+Format type 32h uses the same sub-types but allows to allocate non-default
+amounts of spares. Similar to BD-RE format 31h, three format descriptors are
+offered: #1: default size, #2: maximum spare area, #3: minimal spare.
+The size may be chosen within that range.
+
+The sense behind the Type Dependent Parameters is obscure
+to me. Best will be to set ISA_V and TDMA_V to 0.
+(mmc5r03c.pdf 6.5.4.2.1.17)
+
+
+-------------------------------------------------------------------------------
+Writing a session in SRM:
+
+The procedure and constraints for writing BD-R SRM-POW are very similar to
+DVD+R. libburn flatly re-uses its DVD+R code except the Close Function for
+finalizing a disc.
+
+In short:
+If all written sessions are closed, then there is exactly one NWA.
+In the beginning there is an empty session and track. A new track can be
+written either with pre-announced size (by RESERVE TRACK) or open-end by
+simply starting to write to the NWA. When done the track gets closed by
+close function 001b. Then either session or disc gets closed depending on
+the Close Function used:
+- Close Function 010b closes the session and keeps the media appendable
+  (same as with DVD+R)
+- Close Function 110b finalizes the media and makes it read-only.
+  (differs from libburn DVD+R procedure which uses 101b)
+
+-------------------------------------------------------------------------------
+Pseudo-OverWrite POW: (no used yet by libburn)
+
+This enhancement of SRM emulates overwriting of existing data blocks.
+(mmc5r03c.pdf 4.5.3.5.4)
+
+POW establishes a virtual vLBA space on top of the real address space rLBA.
+All read and write commands deal with vLBA. It seems that track NWAs are
+assumed to be identical in vLBA space and in rLBA space.
+It is not clear whether one may write to vLBA blocks which are neither written
+yet nor at one of the track NWAs. Probably not, or else one could make NWAs run
+into vLBAs which are associated with older rLBAs.
+
+Replacing invalidated blocks consumes addresses in rLBA space at the NWA of
+some track. I.e. no spares are consumed by POW. Nevertheless it is costly by
+a special map called Orphanage. It covers rLBA which have been consumed
+by differing vLBAs. It never shrinks and can grow with each write to remapped
+addresses.
+To avoid heavy Orphanage growth it is advised to write mostly to vLBA which
+still coincide with their rLBA. E.g. those addresses which have neither been
+written as rLBA nor as vLBA yet. So one should begin the vLBA of new sessions
+at the NWA of a sufficiently sized track.
