I have some question about Spare Area.
I know the DVD-RAM and BD-R/RE have the Spare Area. I want to know :
1, how them works?
2, when does the Spare Area be written? right after a defect found during writing, after all the write is finished and then write the spare area? same for DVD-RAM and BD-R/RE
3, there is difference between DVD-RAM and BD-R/RE about spare area?
thanks in advance.
