Using Double-Layer Technology and Media

(Select models only)
Double-layer technology gives you almost twice the
storage capacity of a single-layer DVD and the storage
equivalent of 12 CDs. Double-layer DVD media can store
up to 8.5 GB* of data. You can record on two "layers"
of one side of a DVD. Double-layer technology uses two
thin, embedded, organic dye films for data storage
separated by a spacer layer. Each layer has different
optical properties.
General information about double-layer DVD+R discs:
You can record 3 hours of DVD-quality video or
■
6 hours of VHS-quality video, without turning over
the disc.
This disc can hold up to 8.5 GB. This almost doubles
■
the standard storage capacity of 4.7 GB for the
single-layer DVD+R discs currently available.
Double-layer writing capability is supported by
■
RecordNow! and WinDVD Creator. These are CD
and DVD recording software programs that came
with your HP Digital Entertainment Center.
Double-layer DVD+R discs can only be written to with
■
a double-layer DVD+RW/+R drive.
These discs cannot be erased or written to again.
■
You can use these discs to back up your hard disk
■
drive files.
These discs are able to play back in most
■
commercially available DVD players.
*GB is defined as 1 billion bytes. Actual formatted hard
disk drive capacity is less.

Double-layer media compatibility will vary
with some home DVD players and DVD-ROM
drives.
