Angular moment! and
As frisbee rotates it forces the air to move differently on top and its bottom. The slight difference in geometry generates a lift, similarly to the plane wing (airfoil).

Hold a Frisbee right-side-up, flat, and level and just drop it. It will flip over before it hits the floor.
Now do the same thing, except with a spinning Frisbee. It floats to the floor, still right side up.
Spinning imparts gyroscopic stability, which allows the parachute effect to work. When thrown, the airfoil shape gives it lift. There is a bunch of physics behind Frisbees.

The Gyroscopic Effect

hi,
The spinning both produces lift, in much the same manner as a helicopters blades....
In addition, the spinning stabilizes the frisbee as it flies, by what is called in physics "conservation of angular momentum" - as bicycles which are more stable when you paddle faster...
have a good one...

It's the act of throwing which makes it spin through the air. In fact ANYTHING that is thrown will spin once it is airborne.

the spinning sets up "moment of inertia" which gives it stability, same as a spinning top.

It's a trade secret. However,if you toss a dinner plate or a 33rpm record their lack or aerodynamic stability is plain to see.

Boils down to the good old gyroscopic effect.

gyroscopic physics.
It also has to be heavier around the rim than across the central part

Because it does not get paid to work on the treadmill.
