Wrong, there is no seek with the floppy drives !
You either tell them to move the head one track in the outer direction or in the inner direction , or to not move :-)
Alltough it's true that a head movement is not required : if you try to move the head out of range , then it won't move ( either the drive electronics will not try to move the head or the head will bump into a mechanical stopper and stay on the old position ) , but the CHANGED line will be updated ( the one that signal if a disk is inserted or not ).
