how do you expect to have transparency with a transmit-value of 0 ? :-/

try:

disc {
         0,y,1
         texture {
                 pigment {
                         cylindrical
                         color_map {
                                 [0.0  rgb 0.5 transmit 1]
                                 [0.3  rgb 1.0 transmit 0]
                                 [0.9  rgb 0.0 transmit 0]
                                 [1.0  rgb 0.0 transmit 0]
                         }
                 }
                 finish {ambient 1 diffuse 0}
         }
 }
