6. Frequently Asked Questions
Q: Is the PX-610U a DVD Multi Recorder?
Yes. The DVD Multi specification requires that DVD Multi Recorders
read and write DVD-ROM (prerecorded), DVD-R (General), DVD-RW
and DVD-RAM discs. Because your Plextor drive conforms to the DVD
Multi specification, it can read and write the formats used by today’s
computers and consumer electronic (CE) DVD devices. (Note that DVD
Multi does not prescribe that devices should accommodate DVD-RAM
cartridges or 8-cm discs.)
Q: Which is better, DVD+R and DVD+RW? Or DVD-R and DVD-
RW?
A: Neither is “better” or “worse.” They’re just different standards, like
English versus metric measurement.
Different manufacturers support different standards. The DVD+R and
DVD+RW formats are supported by Plextor, Philips, Sony, Hewlett-
Packard, Dell, Ricoh, Yamaha and other manufacturers. DVD-R, DVD-
RW and DVD-RAM are also supported by Plextor, as well as
Panasonic, Toshiba, Apple Computer, Hitachi, NEC, Pioneer, Samsung
and Sharp.
No matter which format a DVD disc is recorded in, it can be read by
most commercial DVD-ROM players.
Q: What's the difference between "double layer" and "dual layer"?
A: Nothing, really. It's simply a difference of opinion within the
industry about how to label media and drive capabilities. DVD+R DL
(as named by the DVD+RW Alliance) stands for DVD+R Double
Layer. DVD-R DL (from the DVD Forum) stands for DVD-R Dual
Layer. Whether your DL media is labeled "double layer" or "dual layer,"
the PX-610U can handle it.
