So as to not mislead other customers I have removed an earlier comment by myself which was wrong. Unfortunately this removed the reply from the original poster as well.
For info the best practices for removable b2d folders document
(supplied by the original poster)
http://support.veritas.com/docs/239539
does indicate CD and DVD platters are supported (as does the admin guide for BE 2010) although Blue Ray itself is not mentioned.
So this leaves the original poster needing some software that allows realtime file system access to the platter.
It might be worth finding a hardware forum relating to blue-ray drives to post the same question on.
