The top of the tape should be 0.05mm below the top of the upper erase head segment, for the record and playback heads it should be 0.025mm above the top of the upper segments.

That spec. was used in many Sony reel to reel tape decks, a magnifying inspection mirror helps greatly when cleaning or adjusting the tape path.
