摘要： A focus controller for focusing a light beam and positioning the focused light beam onto a signal recording layer of a signal recording media is disclosed. The controller comprises a light beam focusing means having a numerical aperture of 0.6 or more; a focus controlling means for positioning the light beam focused by the light beam focusing means onto the signal recording layer of the recording media; and an offset adjusting means for adjusting an offset between the focused light beam positioned by the focus controlling means and the signal recording layer of the recording media. The controller positions the light beam focused by an objective lens onto the signal recording layer of a recording media; moves the objective lens within a predetermined optical-axial range, detects an amplitude of a signal read from the recording media at either end of the optical-axial range, and adjusts an offset between the focused light beam positioned by the objective lens and the signal recording layer, depending on a difference between the amplitudes of the detected reproduced signal.

摘要： An optical recording medium recording and reproducing apparatus for recording information on an optical recording medium and/or reproducing information therefrom by irradiating the optical recording medium with laser light by the use of a two-group objective lens composed of at least first and second lenses. This apparatus is provided with: a light source for emitting laser light; a first lens for converging laser light emitted from the light source; a second lens interposed between the first lens and the optical recording medium; a detecting unit for detecting a kind of the recording medium; and a movement unit for changing the distance in the direction of an optical axis between the first and second lenses by causing a relative movement between the first and second lenses. Further, the distance between the first and second lenses is changed by the movement unit, which causes the second lens to move, according to a result of a detection, which is performed by the detecting unit. Thereby, the numerical aperture NA of the objective lens is increased. Moreover, the influence of aberration is mitigated. Consequently, the high-density recording and reproducing of information signals can be achieved.
