6. Frequently Asked Questions
Q: What is Blu-ray?
Blu-ray, also known as Blu-ray Disc (BD), is the name of a next-
generation optical disc format jointly developed by the Blu-ray Disc
Association (BDA), a group of the world's leading consumer electronics,
personal computer and media manufacturers.
Q: Is the PX-B310U and PX-B310SA 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.
