Hi,

I am looking at the proposal document distributed at this month’s meeting.

The read and write feature descriptor bits have been re-purposed from disc classes and versions to specific bits for given disc standard. 4 of these bits were actually defined for reading and 2 for writing.

Are these bits actually mapping exactly to the formerly reported classes and versions?

Interestingly, BD-RE Version 1 media can be reported as readable, but not writable. Looks like legacy even before this standard is released – weird. Why not making this bit obsolete as well?

Also, the BD Write Feature version needs to be increased from 0 to 1.

With regards,

David.
