Abstract
To determine the effects of spherical aberration due to defocus and interfe rence of layer 0(L0) and layer 1(L1) in high-density dual layered-discs, 17 sets of discs structures are measured while maintaining thickness uniformi ty of the space layer within +/-1.5 mum for one revolution. After measuring the discs, an optimum thickness of 30 mum of the space layer is obtained.
