not on CD's but DVD's
"-" is just a dash, not a "minus" as in this is a DVD R disk. This
is the original industry standard mostly lead by computing industry
corporations.
about 80% of drives sold to date are "DVD-R" or "DVD-RW"
"+" is a second industry group standard lead by mostly consumer video
corporations - though Sony and others sit on both boards due to
selling products to both segments. (interestingly until recently Sony
only sold DVD"-" units in their computers)
I haven't seen a DVD+R or DVD+RW only drive for a while as now they
mostly are multi format+/-
beyond the "competing industry standards boards" it gets a little
technical and rather irrelevant for consumers beyond the frustration
of compatibility issues
but
for making DVDs probably best to use DVD "-" 's to get the most compatibility.
to read best to have a +/- hybrid to ensure you can read most disks
that come your way...
Could some knowledgeable person or persons please explain the "+"
and "-" symbols used with CD descriptions.
Thanks you
