Akai disk format overview Akai floppy disks are formatted as 2 sides of 80 tracks with 5 or 10 sectors per track. PCs use 9 or 18 sectors of 512 bytes and will not read Akai floppies without reprogramming. As far as I can tell, Mac floppy drives can't read Akai floppy disks at all. Unwritten bytes on a disk are set to zero. This document refers to the first byte in a block as 'byte 1', not 'byte 0'.
All values are decimal unless otherwise stated.
Akai hard disks and CD-ROMs use the same file format as Akai floppy disks, and virtually the same disk format. For example, if a file starts at block 5, map entry 5 may contain the value 6, indicating that the next block to read is block 6. The next block to read is then given by map entry 6. The map entry for the last block of a file contains the value 32768. Unused blocks have a map entry of zero.
