Relief Recording
The DVD Recorder checks the remaining disc space before recording onto a DVD-RAM or DVD-R disc.
And if there’s not enough space, your entire program gets recorded onto the hard disk. This feature also works
if you’ve chosen to record a program and forgot to insert a disc.
High-Speed Recording
Record from the hard disk to a DVD-RAM disc at up to
12x speed. A one-hour program can be transferred in EP mode from hard disk to DVD-RAM disc in five min-
utes.
Progressive Scanning
Progressive Scanning (480P) creates a picture signal with double the scan lines of a conventional DVD in-
terlaced picture (480I), resulting in higher picture resolution.

RAPID MANUFACTURING
With increased competition from the global economy, manufacturers face the challenge of delivering new
customized products more quickly than before to meet customer demands. A delayed development or delivery
can mean business failure. Several technologies collectively known as Rapid Manufacturing (RM) have been
developed to shorten the design and production cycle, and promise to revolutionize many traditional manufac-
turing procedures.
Before production of a product begins, a sample or prototype is often required as part of the design cycle,
to allow demonstration, evaluation, or testing of the proposed product. The fast creation of a prototype is known
as Rapid Prototyping (RP), and is generally carried out before specialized molds, tools, or jigs are designed.
Prototyping traditionally required considerable skilled hand labor, time, and expense, typically applied to cut-
ting, bending, shaping, and assembling a part from standard stock material. The procedure was often iterative,
with a series of prototypes being built to test various options. For many applications, this process has been revo-
lutionized by a relatively recent technology known as layer manufacturing or Solid Freeform Fabrication (SFF),
in which a part of an arbitrary shape can be produced in a single process by adding successive layers of mate-
rial.
RM also includes the fast fabrication of the tools required for mass production, such as specially-shaped
molds, dies, and jigs. Many different layer manufacturing processes have now been developed, using an in-
creasing range of materials. The parts produced have been of steadily increasing size and durability, and as the
quality has improved layer manufacturing is being used more and more frequently to fabricate the parts both for
production tools and functional prototypes. The application of layer manufacturing to make the components
used in production is termed Rapid Tooling (RT). It has been applied to injection molding, investment casting,
and mold casting processes.
For some products, it can be economical to use layer manufacturing to produce the final products them-
selves, sometimes in a matter of days instead of weeks or months. Although the layer fabrication process itself
is typically not as fast as traditional mass production techniques, it eliminates tooling, setup, and assembly
processes, can produce parts of superior quality and complexity, and can be ideal for making custom parts
based on a customer's special requirements. More manufacturers are taking advantages of these techniques.
Layer manufacturing allows parts of completely arbitrary
3-dimensional (3D) geometry to be fabricated, offering designers a new freedom to shape parts optimally with-
out the constraints imposed by forming, machining, or joining. Another important advantage is that the process
