Flatwound strings are all-metal construction and have no ridges to them. Tapewound strings have a smooth nylon tape wrapped around the metal core of the strings. Both are very smooth feeling, and produce a muted tone (as opposed to round-wound). Tapewounds are said to be closer to an upright sound (when paired with the right bass, of course).
Gold Flats are just flatwound strings that use a gold colored metal (80/20 Brass). Gold White Tapes use the same alloy as what is in the Gold Flats, but they have a white nylon tape outer casement.
