Working on the fact that a disc is composed of concentric rings, where the distance on the outer ring is much greater than the distance on the inner, I wonder if it is possible to format each Track with an increasing number of sectors per track (as the head moves towards the edge of the disc)?
Sectors can be 256,512,768 or 1024 bytes long. If this idea worked, it could potentially triple the normal capacity of a 3.5" disc.
Bigger capacity disc idea
Maybe you can interface a Commodore disk drive to Oric? The 1541 et.al use different amount of sectors depending on track. I've recently read that there were some Z80 systems which interfaced with a 1541, and the Oric probably shares more chips in common with a CBM than most home built Z80 systems.

If you want this insanity type drive, fish out an old Apple Mac which had this system on the floppy drive. Really screwed up!carlsson wrote:Maybe you can interface a Commodore disk drive to Oric?

Not bizarre, just unusual, but not so much, some CD readers do that at high speeds.
Since the outer tracks are bigger in length, with the same rotation speed it passes faster under the head. So lowering the rotation makes it pass the same linear speed under the head, but for a longer time, and so with more storable bytes.
