"head" is correct, a floppy is a one-platter disk; to the software it's 
like every other disk except in number of platters and usable size (in 
some disks, maybe only older ones, the top and/or bottom sides are not 
used for data)

There are other possible sizes; I think the original PC had 90k 
floppies. Let me see 8 sectors (IBM didn't realise the drives and media 
could do nine), 256b sectors (I think) 40 tracks.

Oh, there were also single-density 8" floppies, but not on peecees, at 
least as standard equipment.
