Dear MMC members,

=20

Reading mmc5r02b I noticed that for DVD+RW is nicely said in the model
section:

=20

"

Neither Read nor Write commands shall be accepted prior to format of
blank media. When the media is blank

and no format is in progress, the Current bit in both the Random Read
and Random Writable features shall be

zero.

"

=20

I believe the same is true for BD-RE thus should be explicitly said.
((HD) DVD-RAM has these features too but are always formatted thus do
not need the format before Read or Write).

=20

Best regards,

=20
