Are you referring to 2M/2MGUI? That didn't change the track spacing (which is fixed) but used bigger sector sizes (similar to how HDDs went from 512B to 4K physical sectors): https://retrocomputing.stackexchange.com/questions/27412/how-does-2m-for-dos-2-mb-formatted-floppy-disks-achieve-what-it-does https://retrocomputing.stackexchange.com/questions/27412/how...

No they definitely did more tracks, but it seems to be a smaller multiplier than I recalled. https://retrocomputing.stackexchange.com/questions/12768/what-other-tricks-were-there-to-get-more-data-onto-floppy-disks https://retrocomputing.stackexchange.com/questions/12768/wha... 2-5% more tracks, 12.5% more sectors.

  The track spacing didn't change, but yes, many if not all floppy drives could step the head slightly past the officially supported number of tracks.
