/* HD floppy disks */
It is theoretically possible to use HD floppy disks (1.44MB) on CPC by using either a Gotek drive or Amiga HD floppy drives spinning at 150rpm. However, nobody has ever written a CPC DOS to make use of it.
On a real floppy drive, if you want to fit more sectors on the same track, you have two 2 options: you can make the FDC run faster, or you can make the disk spin slower.
Normally, HD disks use a faster FDC (with an automatic switch between the slow and fast modes). But, for example on Amiga systems with HD drives, they used floppy drives that spin slower for HD disks (150 rotations per minutes instead of 300) and this allow to use the same controller as before. By the time the floppy has done one complete rotation, you can write 18 sectors instead of just 9.
