When burning a disc in Magic ISO, one of the options is burning in "Mode 1" or "Mode 2." These options are set up mostly for older disc readers, because any modern computer will have no issue reading any mode. Understanding the different modes will help you learn about the burning process and use for each one.
Mode 1 and 2 are only used when burning ISO files to CD-R discs. The Mode 2 burning format is not available when burning DVD or Blu-ray discs. This applies to any CD recordable disc, including CD-RW discs.
Mode 1 is the updated mode format. When burning a disc, the mode will scan the data multiple times to prevent errors on the disc. This is ideal for data and audio discs. It will prevent corrupted data files and help audio files play clearly. This process uses more memory and can double the burning time in some cases. Mode 1 is the default selection and if you use a "Quick Burn" process, it will automatically select this mode. Older computers with CD-ROM drives may have errors processing this type of disc. In most cases it will work properly.
Mode 2 is a burning process catered to the menus and strings associated with Video CD or VCD projects. When you are burning an ISO of a video disc with menus and options, Mode 2 is the best choice because it can process the data more easily and make it compatible for DVD players. The discs will work in all computers and function as data-only discs or they can load in a media player to replicate a DVD menu.
Test out the different modes based on various projects to see the best results for your own devices. For example, if you have a VCD ISO, burn it once on Mode 1, once on Mode 2 and then test out the discs in a DVD player to see the difference between the two. Repeat this with data discs and audio discs. In most cases, you'll hardly notice a difference between the two, but it depends on the devices that you own.
