Floppy disk drive technology
Floppy disk drive technology
(OP)
Hi,
I am looking for information about the floppy disk drive technology (yes, the old one): the way data are encoded on the disk, materials and technology disks and heads are made, friction, wearing, lifetime, signal/noise ratio at head/disk level, circuitry for directly reading the signal, etc.
We are running measurements by ourself but I would like to understand better the technology. Basic information apart, doesn't seem to be very much around.
Papers, internet pages about this technology.
Thanks in advance,

If you add pdf to the search you can find data sheets

Good luck
RE: Floppy disk drive technology
Expecially the first pointer in Madcow's reply has been usefull.
One information I still miss is the way disks are layered (materials, thickness). I guess patents expired as the technology is quite old.
Thanks very much for the attention.
