We used to drill holes in a 720K floppy so it would advertise itself as a 1.44MB drive.<p>But in the end it&#x27;s all about the density of the disk so I&#x27;m not sure if you could use a driver to store more data.<p>Also you will need very accurate positioning of the head. So the drive is also a limiting factor.<p>I think the largest floppies where 32MB.
