I meant interlaced, and it worked like so:

Each sector on each track of a floppy disk has a sector header, which includes a sequencing value. The sequence value is the order in which the tracks are logically (not necessarily physically) accessed. Normally, floppys were formatted with the physical and logical sequences the same.

However . . .

If you created your own formatting routine, you could change the order so that the sectors (for example) skipped the adjacent sector. For a 5.25" 9 sector/track floppy (360Kb), that meant the order was 1,6,2,7,3,8,4,9,5 . Typically, you'd design your formatting app with various interlace schemes you think are useful (also, for other floppy types) as a set of arrays, and select whichever you wish at run-time. These floppies, once formatted, would read/write on any PC, without any special hardware/software requirement.

Why bother, and/or why haven't I bothered with this in years? These are the same question.

"Way Back When" PC's were a lot slower (12 Mhz 1 wait state), as each sector was read and processed, there was a short delay. During that delay, the read head may have already advanced passed the next sector, and had to wait for it to come around again. In a worst case scenario, with the above track, you had to go around nine times to read one track. I made disks with large .pcx files on them, both the same, except for the interleave. When reading and displaying the files from the disk, The difference was down right dramatic. For smaller files (and less intense CPU work, such as loading ascii text), it was noticably faster, but not earth-shaking. Note that the write-time for a 2:1 interlaceded floppy could be as much as twice of a normal (1:1) interlaced floppy, since it must go around at least twice to read a track - the non-interlaced version could potentially do that job in a single pass.

Nowadays, the CPU's are a bit faster, and the read-cacheing buffers so large, that you'd be hard pressed to notice a difference. Even many (most) hard drives are no longer interlaced.

Good technology for CD/DVD ?? I don't think so. As I recall (maybe I'm wrong?), these are not track/sector formatted media (i.e., the sliced onion look), but are spiral-formatted (like a phonograph record). This would make interlacing a very bad idea.
