Abstract

Two 100 μm cover layer techniques for high numerical aperture (NA) digital video recording system have been developed. For systems with NA of 0.85 at 650 nm wavelength, the cover layer thickness tolerances of ±3 μm within a single disc, up to radius 58.5 mm, are achievable at an average thickness near 100 μm, using the spin-coating of UV-curable resins, or the bonding of a 100 μm thick polycarbonate sheet. Disc tilt and cover layer birefringence comply with the physical requirements of the system.
