Write a Disk backwards
Is it possible to write a disk backwards, say take a D64 probably pre flipped and write it backwards. Maybe run the stepper motor backwards? |

Yeah, a lot of ifs. Might or might not work.
But if you're really going to duplicate 1000 double-sided disks, you'd probably be better off rigging something together with a PC and Kryoflux or Catweasel. |

Are you going to sell the 1571 drives as part of the solution? :) |

Yes it is possible to write it backward but it will not work very well.
While the two heads are physically located above each other the coils are not.
Practically this means the 2nd side head can't reach some of the lower numbered track locations.
So there will be like 4 or 5 tracks worth of misalignment unless the inaccessible lower tracks are skipped and not written.
In my opinion avoiding the side flipping won't gain much as with a bit of practice the majority of time will be spent on writing and verifying the disks. |

I have to say I do like the idea. Pity it seems to face a lot of obstacles. |

Is this why the 1571 is 35 tracks only. In that its actually 40, just it uses the inner 35 on the top side and the outer 35 on the bottom? |
