Hard drive space
Writing data on a CD-R/RW disc requires 50 MB to 100 MB of free space as
a working area on the hard drive. When writing data on a CD-R/RW disc
after creating an image file, there must be enough free space on the hard
drive to store the image file in addition to the working area (a total of up to
about 900 MB). However, this hard drive space for image files is not needed
when directly writing onto a CD-R/RW disc from a hard drive or CD-ROM
using the CRW-70 drive (on-the-fly writing).
Image files
You can collect data files to be written on a CD-R/RW disc into a single image file.
The image file is useful for writing the same data onto multiple discs. For further
details, refer to the documentation that came with your CD writing software.
Your drive’s serial number is printed on the label affixed to the bottom of the
drive. You may be asked for the serial number when requesting information
about your drive or user support services. It may be difficult to read the serial
number because of the installation location or for other reasons. YAMAHA
therefore recommend you note down the serial number in the box below for
future reference.
