With so many different formats —
DVD+R, DVD+RW, DVD-RAM, DVD-R, DVD-RW, DVD-ROM — how do users know which DVD
Format is compatible with their existing systems, and why are
there so many different formats for DVDs?
The following information sheds some light on DVD's different flavors, the
differences between them and the incompatibility issues that the differing
technologies have sprouted.
The crucial difference among the
standards is based on which standards each manufacturer adheres to. Similar to
the old VHS/Beta tape wars when VCRs first hit the markets, different
manufacturers support different standards. Additionally, the different
variations on the term DVD (e.g. +R, -R, -ROM, and so on) describe the way data
is stored on or written to the disc itself. These are called physical
formats.
