A 92 Samurai takes a vee belt, some vee belts have teeth or as you say "cogs" on the inner surface, some don't, I've never seen one with teeth/cogs on the outer surface. Look at the edges of both the old & new belts - there should be a noticeable taper or vee (hence the name) - the vee has to match the pulleys on the engine, so the narrow part of the vee sits lower down in the pulleys.
