Abstract
The authors have proposed and fabricated several types of waveguide-type integrated-optic disc pickups. The key components are various kinds of holographic micro components for wavefront conversion. These are gratings that are written by a computer-controlled electron-beam scanning system. The ROM pickup for compact discs, for MO discs and for parallel-data cards have been demonstrated.
