The '''A2R disk image''' format is a low-level, high-resolution capture of the contents of an Apple II disk. As such, it is much larger in size than other formats such as the [[WOZ disk image]] format which attempt to duplicate the data that was originally written to the disk; A2R captures the raw magnetic patterns of the disk, often easier to do in the case of old, barely readable disks, but needing further processing to recover the original data.
