This is a DVD+R/+RW concept. In DVD+R/+RW, the organization is
physically the same, and pie-slice MO, hence why you don't understand
how DVD-R is different.
You _never_ "erase" DVD-R.
It is not MO, it is not the same, physical organization as DVD+R
(or DVD-RW/+RW for that matter).
When people "emulate" a CD-R or DVD-R with CD-RW or DVD-RW using
"cdrecord," it is still a completely _different_ physical format, hence
why it typically doesn't work well. You're telling cdrecord to just do
the "jaggy write" -- i.e., head moves outward, in one, discrete motion,
at the end of each revolution, instead of a gradual, single track.
cdrecord doesn't recommend it, but if you do it, it's up to the reader
to read it.
Most won't unless they are recent.
DVD+R is already physically like DVD+RW, so there is no difference (and
it neither were ever designed for cdrecord or any linear, single-groove
recording program). DVD+R has _never_ been a "single-groove," hence why
cdrecord is wholly inappropriate (just like any -RW/+RW format).

Just FYI, unlike DVD-RW/+RW, despite also being MO, you _never_ "format"
DVD-RAM for that matter. It is physically pre-formatted. Those who've
seen DVD-RAM know exactly what I mean.
