[Image Copy]
This backs up contents in the disk in iso image file formats.
Once back-up is complete, user's data is saved in subfolders created by back-up date
under service/back-up/disc-image folders. If back-up takes place more than once on
one day, a serial number will follow the date.
However, Image Copy will not function properly in one of the following cases:
① If the optic disk is copyrighted, 'unsupported disc' message will appear on the
LCD and back-up will not be processed.
② Disks recorded in multi-sessions will not support Image Back-ups.
