dvd or cd plus or minus signs

Can someone please tell me the reason for the plus and minus signs between cd/dvd and r/rw i.e. +/- ?

cd's are only -

DVD's come in + or - formats. They are different formats. In reality I don't think there is a huge difference between the two. All new player/recorders cope with both formats.

I have always followed advice the minus for audio visual and the the plus for data.

but with improvements these days there may not be any difference.
