3.5" Floppy Disk Drive Question

Hello,

I am looking for information on what the pins on a standard IDE 3.5" floppy
disk drive do. That is, I know that pin 20 is "Step Pulse", pin 22 is
"Write Data", pin 8 is "Index", etc., but I cannot find information on what
the pin's functions are. I need the information so I can build a circuit
that can read/write data from/to the drive. I've have looked all over the
place for the information, including the Internet and a major research
library but I have been unsuccessful. If anyone knows what the pins on a
standard IDE 3.5 inch floppy disk drive do or could offer any advice on any
resource to check, I would greatly appreciate it. Thank you in advance for
any help.

Thanks,
Scott H.

Uhm...

Just get a controller chip and use that... it's why they exist.

BTW, most of the pin labels are pretty self explanetory. "Step Pulse"
is a pulse telling the drive to step the head. "Index" pulses when the
index hole makes one revolution, etc.

This is what came out of google in less than a minute:

Good luck,
