Application No. 07/855,442
wherein the composite dielectric layers are formed of x
mol% of aluminum nitride and (100 - x) mol% of silicon nitride
such that x is greater than 0 and less than or equal to about
95 mol% and the refractive index of the composite dielectric
layer is between 1.70 and 2.15.
13. A composite dielectric layer for use in an optical
recording medium comprising x mol% of aluminum nitride and
(100 - x) mol% of silicon nitride such that x is greater than
0 and less than or equal to about 95 mol% and the refractive
index of the composite dielectric layer is between about 1.70
and 2.15.
