Abstract: PURPOSE:To reduce the probability of erroneous discrimination by collating second personal feature data with corresponding individual feature detection data when first individual feature data and corresponding individual feature detection data do not coincide with each other. CONSTITUTION:First individual feature data read out from a recording medium like a card by a card data read block 30 and corresponding individual feature detection data detected by a fingerprint detecting block 32 are collated with each other, and a second individual feature data is read out from the recording medium during this collation. If the collation results in disaccord between first individual feature data and corresponding individual feature detection data, second individual feature data and corresponding individual feature detection data are collated with each other. Thus, the probability is reduced that identification is not decided though the individual related to fingerprint data recorded on the recording medium is the holder of the recording medium.

Abstract: PURPOSE:To miniaturize a constitution and to reduce cost by using the optical path of laser beams for recording and reproduction and that of the laser beams for position detection in common and using the laser beams from one laser diode as the laser beams for recording and reproduction, and those for position detection. CONSTITUTION:At the time of reproduction, a synchronizing clock accompanied by the shift of the spot position of the laser beams projecting on the recording and reproducing surface 10A of an optical card 10 can be obtained from the detection output of an optical detector 12. At the time of reproducing, the synchronizing clock can similarly be obtained from an output that is obtained by dividing the detection output of the optical detector 12 by the detection output of the optical detector 6, or an output obtained by dividing the detection output of the optical detector 12 by the driving current of the laser diode 1. Thus, the optical path of the laser beams for recording and reproduction and that of the laser beams for position detection are used in common, and the optical system of the optical recording and reproducing device can be miniaturized.

Abstract: PURPOSE:To prevent stain, etc., from being detected by mistake with a recording part after the data are recorded by making the reflection factor of the recording part after the data are recorded higher than the reflection factor before the data are recorded and more equal than the reflection factor of a pre-format. CONSTITUTION:To an optical card 10, an address pattern 15 where an address signal is recorded and a guide track 16 are formed. For these pre-format patterns, a laser beam is projected to the part of a corresponding recording medium and the reflection factor is made into for example, double compared with the periphery. To the card 10 formed as shown in the above, the data is added and the top of the track 16 is made into a recording part 17. To the recording part 17, a data pattern 18 is formed. For the part of the pattern 18, the reflection factor is made into, for example, 6 times compared with the peripheral part. In such a card 10, for example, when the stain is generated, the stain 6 is operated in the direction to reduce the reflection factor. Consequently, the level of an output signal SN of a detector corresponding to the stain 6 is lower than a signal SR.

Abstract: PURPOSE:To reduce the dimensional accuracy of an optical card with no deterioration of the information recording density of the card, by using a correction means like a correction plate, etc. to correct the out-of-focus state due to the variance of thickness of a transparent protection film of the card. CONSTITUTION:An out-of-focus state is produced when the thickness of a protection film 3 is equal to (t+DELTAt) due to the variance of size of an optical card, etc. Thus a thickness correction plate 20 having the refractive index nc and the thickness D is used for correction of said out-of-focus state. The change degree DELTAl of the optical path length owing to the plate 20 is equal to (1-1/nc)D with both recording and reading beams LB and RL. Then the out-of-focus state is corrected when the coincidence is secured between the defocus degree a and said change degree DELTAl. Therefore the thickness D=DELTAt/ns(1-1/nc) is required for the plate 20 when the refractive index of the film 3 is defined as ns.

Abstract: PURPOSE:To reduce the length of an optical head in the optical axis direction of an objective by shifting together the objective, the semiconductor laser of a light source and an optical system including a photodetector. CONSTITUTION:An optical head contains a semiconductor laser 21 which forms a light source, a polarized beam splitter 22, a 1/4 wavelength plate 24, a rectangular prism 25, an objective 26, a photodetector 28 which detects the laser light reflected by the splitter 22, etc. in one body. Such an optical system is shifted toward the optical axis of the lens 26 as well as in the direction rectangular to said optical axis for purposes of focusing and tracking respectively. Therefore it is possible to reduce the size of the objective 26 as well as the distance between the objective 26 and the prism 25 in comparison with the case where only the objective 26 is shifted. As a result, the length of the optical head can be reduced in the optical axis direction of the objective 26.
