Paper Abstract

A newly optical pickup using integrated optical unit (IOU) which can detect spherical aberration error signal (SAES) and control light intensity distribution is described. In this IOU, the SAES is detected by hologram and light intensity distribution is controlled by grating. In addition, spherical aberration (SA) servo for a dual-layer Blu-ray disc is demonstrated by using this SAES.
