Recording TV Programs to DVDs 103
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.
