About the disk format: the Amiga native disk format was just one huge sector per track. That is how the Amiga fitted 880K on the same disk MS-DOS filled with 720K and MacOS 800K.
One of the custom chip on the Amiga had hardware for teh track decoding. So the Amiga could read the disk while performing other operations, the data would come in via DMA (direct memopry access) of the co-processor.
(MacOS used variable-speed, that is how it fitted more sectors on outer tracks and achieved 800K.)
