This was a somewhat popular program at the time:<p><a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;2M_(DOS)" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;2M_(DOS)</a><p>It worked by combining two completely separate techniques; the first, using more tracks, is pretty self-explanatory --- a lot of floppy drives, despite officially supporting 80 tracks, could actually move the head to 81st and 82nd tracks (rarely, even higher), and since the media was in the form of a uniform magnetisable disk, that let an extra 2 tracks worth of data be accessed.<p>The second technique was to reduce the number of sectors per track and the gaps between them, by making each sector bigger. To ensure interoperability with different drives rotating at different speeds, there&#x27;s actually quite a lot of &quot;padding&quot; between each sector, as well as ID&#x2F;CRC data for each one. If I remember correctly, in the highest capacity mode, 2M wrote only <i>one</i> huge sector per track instead of over a dozen in the usual format. This is similar to how hard disks have transitioned to using 4KB sectors internally, instead of the traditional 512B.
