Absolutely correct!  Each track is just a circular buffer, but there's no specific size it really has to be -- it's just a certain size by convention because that's how it was originally implemented.  As for what goes in each track, it is really up to the format.  The RWTS on the firmware is responsible for locating the header for a desired sector and translating the data, and that's where protection schemes start off (assuming they don't do anything funky like half or quarter tracks)
