Abstract

An objective lens system (20) is described which is designed for to scanning an information layer (13) of an optical record carrier (12) by a radiation beam (25). The objective lens system comprises an annular area (B) that is designed for focusing an annular part of the radiation beam (25) onto a label-layer (14) of the optical record carrier such that improved label-writing is obtained.
