Kuldar,
Of the 3 predominant DVD formats, most drives will read and write DVD+R and
DVD-R, The other format DVD-RAM is a different format.
A colleague just reminded me of the old 5.5 inch floppy disks. They used to
have a notch in the side, and you would put a sticky label over the notch to
write protect them. Then they had double sided disks that allowed you to
turn the disk over (LP style).
The only difference between a single and double sided disk was the presence
of the notch, so everyone just cut a notch with a hole punch or some
scissors.
Ah memories of the Apple IIe and Karateka...

Hi everyone,
I wouldn't quite say that DVD is a well established standard - there
are still several standards with minor differences. The most obvious
examples are DVD-R and DVD+R.... Also, I'm not quite sure how much do
differ discs from different vendors? As I'm not really a specialist in
this field the question - has anyone more information about this topic?
