摘要： To stably carry out recording and reproducing to and from a high density optical disk without using a double servo in the optical disk using a high NA objective lens. A detection of a spherical aberration and a detection of a coma aberration in a radial direction are simultaneously performed, and the coma aberration generated with the offset of an objective lens 109 is corrected in real time, thus enlarging an allowable offset amount of the objective lens. In order to simultaneously detect the spherical aberration and the coma aberration, focal shift and tracking shift signals in an inside region and outside region of reflected light flux are detected respectively, and the differential signals are set as spherical aberration and coma aberration signals.

摘要： The amount of focus offset and the amount of spherical aberration correction are adjusted with respect to a disk on which no data is recorded with high precision. The amount of focus offset and the amount of spherical aberration correction are adjusted on the basis of (1) a focus error signal amplitude, (2) a tracking error signal amplitude in a wide track pitch region, and (3) a rectangular waveform wobble signal envelop level.

摘要： A focus error detecting method and an optical head using it. In the focus error detecting method, a light beam is emitted from a light source, the beam is given positive and negative astigmatism by a diffraction grating or an acoustooptic element in a focusing optical system, beams thus formed are focused on an information recording surface, the beams reflected from the information recording surface are received by photo-detecting elements in separated optics, the reflected beams with positive and negative astigmatism are compared with each other to take a difference in a focus error detecting circuit, and a focus error detecting signal is obtained on the basis of the difference. The focus for the optical head can be adjusted using the focus error detecting signal.
