I would like to experiment by interfacing a floppy drive to a micro-controller systems...

I would like some advice on this....

The two ways that I know this can be done is by
1. FD Controller
2. Direct control by my controller.

Which is a more prefered way? In terms of the economy? Do FD Controllers cost more than a controller with i2c bus?

I am willing to use a 2nd controller if all IO lines of one get used for the floppy disk controlling operations...
 

May be this link will be helpful, but i general I think that better way is use CF or SD card, because floppy will dissapeard in the future :)

HI ..this brings old memories ...well.the only way possible is to use an old ISA (8 bits ) floppy controller ..beacuse the floppy drive only outputs MFM format data ,to get binary code ,that requires complicated demodulation that is done in the floppy controller .In other words the floppy controller is not just a bunch of registers to hook to the ISA bus ..is also a big part analog .. and the other half of the floppy subsysem drive ..
IS not over !..then you need a disk structure to store data ..i mean a format

by the time you are done ..you will spend too much time .adn is a knowledge that is OBSOLETE ..you won't be able to use it in any thing,...look at me ..i use to do this type of designs ..and now nobody ask me to do it anymore ..
 

Thank you...

My question was not so much technical... I wanted some wise advice and I got it...

Thanks again...
