An object of the present invention is to provide an optical pickup apparatus which changes characteristics of a light-emitting device or hologram to reduce problems of track servo deviation due to scratches on a surface of an optical disc. By aligning a photoreceptive domain for focusing error signal (PDf) and a photoreceptive domain for tracking error signal (PDt), even in a case where scattering light made by a scratch in the tangent direction of a track of an optical disc reaches the photoreceptive domains, light diffracted in a HA+B domain of a hologram pattern does not enter into photoreceptive portion F or G of the PDt. Therefore, scattering of light which enters the PDf does not influence a tracking error signal (TES), so that the TES does not become abnormally large, and track servo deviation can be prevented.
