Floppy formatting questions

Hello geeks,

I'm new to assembly and file systems. I'm trying to understand how
floppy disks work, but I cannot explain myself several things and I
though you could help me:

1. A normal 3.5'' formatted floppy disk is 1.44 MB, right? An
unformatted one is 2.0 MB? What does this format mean ... is it the
file system or not? Where are the missing 0.56 MB? I read somewhere
that it had to do something with the fact that the floppy disk secrots/
tracks (not sure which one of the two) are too near and generate
errors ... and therefore some are ignred...

2. Can I write my own formatting program? I mean not only developing
my own file system, but also format the floppy disk so that it uses
not only 1.44 MB, but 1.68 MB for example, or why not the whole 2.0
MB...

I will be very thankful if you provide me some links so that I can
read some theory...

Thanks in advance! ;)
