A USB floppy drive that can download/upload the analog MFM waveform from/to the disk and encode/decode it in software. With this drive you can read your old Amiga disks on your PC as well as any other format that you can think of. The deluxe version will have three slots, one each for 8", 5.25", and
3.5". You would also be able to write PC disks as well (up to 2.88 MB).

I very much like this concept, especially since such a drive could probably do a better job than most existing drives at reading disks which are getting flaky. |
|
| |
You'd have to have some way of auto-detecting the track layout too. Might I humbly submit that the drive takes a high-density two dimensional magnetic map of the entire surface, and then deduces both the track and the data in software? |
|
| |
Doing a full 2d map would probably be overkill for anything except some spiral-track disks recorded for the Apple II series of computers. For just about anything else, it should be sufficient to advance the head in sub-track steps and simply search for the best signals. |
|
| |
Sure, but you want this to be able
to read everything, and Apple IIs
would have to be some of the
more common 5.25" and 3.5"
disks out there. And what about
2.8" Quickdisks? Nothing reads
those f---kers. |
|
| |
While a full 2D map may indeed be
ambitious, the spiral track could
probably be followed with a bit of
careful head seeking as you
describe. |
|
| |
Proper processing of spiral tracks would basically require forming a full 2d map of the disk. The type of head-seeking I described would be much too slow to handle non-circular tracks. Assembling the data for spiral tracks from multiple read passes would probably still be difficult, but I would expect that modern computing power would at least render it feasible. |

I'm with Bunsen on this one... do a read, then make it a software problem. |

Can some one please give me a model number for this drive as I would like to try and find one, especially the dulux version? PLEASEEEE!!! |
