These are all comments based on the rev 100 DRAFT spec:=20

Editorial Requests:=20

*	DVD-R DL sections are not clearly titled.  To simplify TOC view
of finding DVD-R DL sections, I would like to request the following
editorial change:

*	Create new section 4.17.5 titled "DVD-R DL Layer Jump
Recording".  Move current sections 4.17.5 through 4.17.11 under this =
new
section.
*	Titles of these sections may also be simplified (i.e. "Recording
Unit of Layer Jump Recorder" --> "Recording Unit", "Layer Jump =
recording
on Invisible/Incomplete RZone" --> "Invisible/Incomplete RZone
recording", etc.)
*	Sections 4.17.12 and 4.17.13 are renamed 4.17.6 and 4.17.7
respectively.

*	17.32 RESERVE TRACK command

*	Please update sections 17.32.1 and 17.32.2 to indicate ARSV bit
settings for clarity.  Also indicate for 17.32.2 that this is the =
legacy
mode, or swap order of sections 17.32.1 and 17.32.2, as legacy behavior
is often shown first.

*	17.43 START STOP UNIT command

*	Please update table 617 (Actions for Eject/Load Disc) to show
layer jump combinations also.    Required are:
*	Operation: Layer Jump to same layer, No media =3D=3D CHECK
CONDITION, 2/3A/??
*	Operation: Layer Jump to same layer, Media Present =3D=3D No Error,
No Change
*	Operation: Layer Jump to new layer, Media Present, Locked  =3D=3D
CHECK CONDITION, 5/53/02 =3D=3D (No Error, No Change) for all cases

*	READ CAPACITY: Change LBA field from "reserved" to "shall be set
to zero", to enforce LU checking this value is valid.  This is because
the field is defined.


In addition, the most recent (rev 100) draft has caused some number of
changes to the number of "valid" or "defined" bits in various commands.
Therefore, it is important that the host can know the logical unit is
properly validating the additional size in the various commands.  =
Rather
than updating multiple features, I think this can be very easily done
with a minor modification to the CORE feature:

*	Update CORE feature version to 2.  Add a bit to indicate the
following:

*	INQUIRY data Allocation Length is two bytes in length.
*	INQUIRY data format length update.
*	LLBAA and Subpage bits are checked for valid setting by logical
unit.
*	Mode field of READ BUFFER command is checked to five bits length
by logical unit.
*	LBA field of READ CAPACITY is checked by logical unit.
*	Mode field of WRITE BUFFER command is checked to five bits
length by logical unit.


Although this is a minor change, this final item may not be considered
editorial. I therefore request consideration for this change from =
member
companies via this reflector.  Please consider this change and reply by
reflector if there is any problem with it.

Sincerely,=20
