Abstract: PURPOSE:To prevent the frequency characteristic of a reproduced signal from being deteriorated even if the width of an annular beam spot is narrow, by forming a blind area arranged between the 1st and 2nd detecting parts of a photodetector into a polygonal shape having a prescribed positional relation with the annular beam spot. CONSTITUTION:A separating blind area 18C formed like a square or the like is arranged between the outside and inside photodetecting parts 18A, 18B of a photodetector 18 detecting an annular beam spot S in order to detect focus status. The square has a fixed positional relation with the spot S so that the corners are arranged on the outside of the spot S and a part of sides are arranged on the inner circumferential side under the focused status and the length of arcs of the spot S is made coincide with each other on the outside and inside of the blind area 18C, so that the quantity of photodetection of the detecting parts 18A, 18B is uniform at the time of focusing. In said constitution, the part of the spot S made incident to the blind sector is made smaller than the case of a circular blind area even if the width of the spot S is narrow and prevent the frequency characteristic of the reproduced signal from being deteriorated without the reduction of S/N ratio.

Then a focus error signal, a tracking error signal and a tilt error signal of optical axis are produced on the basis of the difference between the photodetecting output sums of regions E-G and A-D, the difference between the photodetecting output sums of diagonal regions E, G, A and C and F, H, B and D, and the photodetecting output sum of all regions A-H. In such a way, it is possible to obtain an optical reproducer which has an easy-to-control constitution and can perform the stable and accurate control by the compelmentariness of those symmetrical photodetecting regions with a highly efficient use of light.

Abstract: PURPOSE:To ensure the stable and accurate optical reading with high efficiency through an optical system which can be easily controlled, by forming the photodetecting part of a photodetector which receives the reflected light from a recording medium with the center part of four photodetecting parts and adjacent two photodetecting parts outside said center part. CONSTITUTION:A reading laser luminous flux reflected from an optical disk, etc. is made incident to a photodetector containing a center part and adjacent two sets of photodetecting part 27 and 26 outside said center part via beam splitter, etc. Four photodetecting regions E-H and A-D which are symmetrical to each other are provided at the parts 27 and 26, respectively. The focusing is controlled from an optical reading device on the basis of the difference between the photodetecting output sum of regions E-H and that of regions A-D. Furthermore a tracking is carried out on the basis of an error corresponding to the difference between the detecting output sums of diagonal regions A, E and G and B, D, F and H. Thus it is possible to perform the stable and accurate optical reading with high optical efficiency through an optical system which requires no critical light prism, etc. with no use of three spots and without giving any effect to an optical shift, etc. due to the complementariness of a symmetrical constitution.

Abstract: PROBLEM TO BE SOLVED: To record additional information on an optical disk while solving the problem of the recording jitter. SOLUTION: A continuous single signal for making an additional information recording area is not recorded in a synchronized signal recording area in the optical disk, but recorded in a data recording area in advance (S100). In recording the additional information, a rotational servo is applied, referring to the synchronized signal recorded on the optical disk PD (S102), and a TOC (table of contents) is read (S104). A leading address of the additional information recording area in which the single bit string 3T signal is recorded is read on the basis of the TOC (S106), and the access position of a recording laser beam is controlled, aiming at the leading address (S108). With the synchronized signal as the reference starting therefrom, a rotational lock (phase lock) in the time axis direction is applied (S110), and the additional information is additionally written, by irradiating the single bit string 3T signal recorded in advance with the laser beam when the rotational servo is stabilized (S112).

Abstract: PURPOSE:To reduce the size of a magneto-optical disk apparatus. CONSTITUTION:A laser diode light emitting optical system 7 and a photodiode light receiving optical system 8 are arranged on the same plane parallel to the surface of a magneto-optical disk 4 and the light beam is bent with a beam splitter 6. Moreover, the direction of the light beam incident on a 45-degree mirror 2 provided at the lower side in the vertical direction of an objective lens from the beam splitter 6 is set less than 90 degrees toward a motor for the direction of the line connecting the motor 3 and the 45-degree mirror 2. Thereby, the apparatus is reduced in the thickness and moreover physical area can be reduced because an optical pickup device can be provided within the projected area of the magneto-optical disk 4.

Abstract: PURPOSE:To easily set the value of a minimum recording trace pitch to a desired value by making an angle of a linear lattice part in a light beam scanning detection means variable to a direction orthogonal to a direction of lattice extension with respective to a line scanning direction of a 2nd light beam. CONSTITUTION:The recorder is provided with a card support 11, a light beam incidence control section, a recording signal transmission section 60, and a light beam driving means modulated based on a recording information to scan a 1st light beam made incident in an optical card in a prescribed direction with respect to the optical card and to write the recording information signal onto the optical card. In such a case, an angle of a linear lattice section 52 of an optical beam scanning detection means 50 to a 2nd light beam line scanning direction orthogonal to a direction of the lattice extension is varied to change the pitch in the 2nd light beam line scanning direction. Thus, the value of a minimum recording trace pitch in the write of the recording information signal with respect to the optical card is set to a desired value with very easily and high accuracy.

Abstract: PURPOSE:To adjust an azimuth without recording onto a card and to minimize an azimuth error after the adjustment by providing photodetectors that monitor the return light from a reference card respectively for a recording optical system and for a reproducing optical system and adjusting the azimuth of both of these optical systems independently. CONSTITUTION:The photodetectors 66 and 60 that monitor the return light from the reference card recorded the prescribed pattern at its reference edge are provided on the recording optical system 12 and the reproducing optical system 14, respectively. The azimuth adjustments of the recording optical system 12 and the reproducing optical system 14are carried out independently. The azimuth adjustment of the reproducing optical system 14 is carried out as conventional. The azimuth adjustment of the recording optical system 12 is carried out as follows: the photodetector 66 is provided and a laser optical source 20 is caused to emit light by a low DC power, the reflected light from the reference card 10 is detected by the photodetector 66 and the azimuth adjustment is carried out by watching the detected output wave form by a monitor 72. Thereby, an azimuth error is minimized. The azimuth adjustment of the recording optical system is carried out without actually recording onto the card.
