An optical disk device (1) for reading and/or writing an optical disk (100) having a tilt corrector, characterized in that the optical disk device comprises a measurer for measuring tilt at an inner circumferential part and at an outer circumferential part of an optical disk and a selector for selecting, in dependence of the measured difference (STILT) between inner and outer circumference tilt value (TILTin-TILTout), a tilt correction curve (curve 1, 2, 3, 4, 5, 6) for determining the tilt correction as function of radius of the disk, at least some of the selectable curves being of curvilineair form.
