Abstract: PROBLEM TO BE SOLVED: To make a laser beam shorter in wavelength and an optical system higher in aperture and to enable stable and sure focus control by executing focus control by a focus error signal obtd. by synthesizing first and second focus signals varying in a signal level change with respect to a change in a defocus quantity. SOLUTION: The focus error signal TFE is formed by the second focus error signal FE2 of high sensitivity in a small range of the defocus quantity and the signal TFE is formed by correcting the signal level of the first signal FE1 in a wide focus controllable range on the outer region of the focus controllable range of the second signal FE2 at the time of synthesizing the focus error signal TFE in a synthesizing circuit 56. The signal TFE of the high sensitivity and the wide focus controllable range is thus formed by the second signal FE2 of the high sensitivity and the first signal FE1 of the wide focus controllable range in the synthesizing circuit 56. Then, the focus control is executed with the signal TFE.

Furthermore, the track direction middle area is divided into at least two in the direction orthogonal to the track direction and the photodetector 9 is further divided into two in parallel with the track direction. Consequently, two light receiving areas E, F are formed in the edge areas in the track direction at the upper side in a figure, two light receiving areas H, G are formed in the edge areas in the track direction at the lower side in the figure, and light receiving areas A to D are formed in the track direction middle area.

Abstract: PROBLEM TO BE SOLVED: To anneal the magnetic layer of boundary wall surface between recording areas, for example, lands and grooves, in a short period of time with certain annealing power in the manufacture of a magneto-optical recording medium. SOLUTION: A laser beam emitted from a laser beam source 2 is divided with a grating member 4 to form an annealing beam and a tracking detection beam. Of these beams, at least the annealing beam is divided, for example, by a wollaston prism 6, to simultaneously irradiate a plurality of boundary wall surfaces with at least two annealing beams. The composition of an annealing beam emitting device 1 is selected so that the angles and polarization planes to each of the boundary wall surfaces of the optical axes of at least the two annealing beams may be nearly equal.

Abstract: PROBLEM TO BE SOLVED: To obtain the phase difference controller which stably operates without being affected by external environment by detecting a phase difference and performing feedback control over an electric signal so that the phase difference becomes equal to a target phase difference. SOLUTION: A phase difference varying element 1 varies the phase difference with the electric signal. A phase difference detecting means 2 comprises a phase difference detecting optical system 21 and a phase difference detecting circuit system 22 and detects the phase difference. A phase difference control means 3 comprises an error signal detection part 31 and a drive circuit system 32, and performs the feedback control over the electric signal so that the detected phase difference matches the target phase difference. Namely, the phase difference detecting circuit system 22 generates a signal Sout representing the phase difference from the signal detected by the phase difference detecting optical system 21. The error signal detection part 31 generates an error signal Er of the signal Sout based upon the target value. The drive circuit system 32 controls the voltage applied to a liquid crystal panel 1-1 so that the error signal Er becomes 0.
