Abstract: PURPOSE: A solid immersion lens of an optical recording and playback apparatus and a method for manufacturing the same are provided to increase an effective aberration of a near field pickup optical system. CONSTITUTION: A flange part(21a) has a predetermined area and a certain thickness, and increases an effective aberration of a lens. A lens part(21b) is protruded from one side of the flange part in a hemispherical shape. A plurality of hemispherical grooves are formed on a processing surface of a mold frame. A buffer film is applied to inner surfaces of the hemispherical grooves including the processing surface. A high refraction material is deposited in the hemispherical grooves including the processing surface. The high refraction material is flattened to form the flange part. The mold frame is removed and the buffer film is selectively removed to form a solid immersion lens(21) having the flange part.
