5. Move the slider to one of the GigaRec Rate numbers to select the
capacity. For example, choosing 1.2x increases the disc’s writing
capacity by 20 percent. So the capacity of a 703-MB disc is
increased to 850 megabytes (Mode 1), or about 96 minutes.
NOTE: MSF stands for minutes, seconds, frames. This is the structure of
the CD: 2048 bytes per frame, 75 frames per second, 60 seconds per
minute.
6. Using a disc-at-once (DAO) recording application such as PlexTools
Professional CD/DVD-ROM Maker or AudioCD Maker, record data
on the CD-R disc.
7. To disable GigaRec and return to normal writing, clear the Enable
GigaRec check box.
How GigaRec Works
CD-R and CD-RW discs are manufactured with special information
about manufacturer, model name, disc features, and maximum write
capacity written to a narrow strip along the inner margin of the disc. The
Plextor PX-712 can ignore and even overwrite this information, which
extends the disc capacity.
Important Facts about GigaRec
•
When you enable GigaRec, it is active for all recording functions.

With GigaRec, writing speed is fixed at 4X or 8X.
•
You can use only CD-R discs with GigaRec.
