halves". One half looks like an "upper and lower" for the two tracks, then next to that is a "vertical bar." I've never quite understood what that vertical bar is - I assume a WRITE portion of some sort?? The ones in the ebay listing don't have this "vertical bar."
That is the erase head.
Then the pins on the back of the head: the one I have for my 5100/5110 is "6 small pins" next to "4 fat pins" (the 4 fat pins are in line with the "vertical bar" mentioned above). Of all the heads I came across, I could find the "6 small pin" configuration, but never the "4 fat pins."
My guess (System Logics Manual page 435 seems to support this) 6 small pins: the two center-taped read-write-heads 4 fat pins: the two erase heads Christian
