Abstract: PURPOSE:To realize a thinner type by reducing the height of the whole optical system and to manufacture recording optical system and reproducing optical system as an individual optical block by leading the reflected light of a reproduction light to a line sensor via the reflection light path independent from each incident light path. CONSTITUTION:The incident light path onto the optical recording medium of the recording light of recording optical systems 15-17 for recording an information signal on an optical recording medium 2, the incident light path onto the optical recording medium of the reproduction light of the reproduction optical system 30 for reproducing the information signal recorded on the optical recording medium and the reflection light path by the optical recording medium of the reproduction light of the reproduction optical system 30 are provided independently respectively. The structure projecting a recording light from about vertical direction on the optical recording medium 2 by bending it at the vicinity of the optical recording medium 2 by a light path changing means in the recording optical systems 15-17 is taken. A thinning type can thus be realized by reducing the height of the whole optical system, the recording optical system and reproducing optical system can be formed as an individual optical block by giving a room to the fitting accuracy of an optical part and the cost down can be realized as well.

Abstract: PROBLEM TO BE SOLVED: To provide a disc storage case for storing and carrying a disc-shaped recording medium, and a recording medium stored in such a storage case that allows the recording medium to be stored or removed easily and certainly. SOLUTION: The disc storage case stores the disc-shaped recording medium 21 in such a way that the recording medium is held on its one surface side and the other surface side in a sandwiched manner. This prevents application of a stress to the recording medium 21 upon storing or taking out the recording medium 21. COPYRIGHT: (C)2005,JPO&NCIPI

Abstract: PROBLEM TO BE SOLVED: To record, reproduce, and evaluate appropriately intrinsic information (UDI) of an optical disk medium by using arbitrary data.
SOLUTION: A PN signal (pseudo random signal) is generated by a PN signal generator of a UDI encoder section 10 at the time of recording a UDI signal, this signal is write-controlled by a formatter, data are supplied to a disk recording device, and a disk recording device records the UDI signal in a CD. Also, at the time of reproduction of the UDI signal, UDI digital data obtained through a UDI detecting circuit (low-pass filter) from an RF signal (e.g. 3T single signal) from a disk reproducing device are stored in a data buffer, compared with write-data of the PN signal generator, and an error rate is measured by a bit error counter.

Abstract: PROBLEM TO BE SOLVED: To record additional information on an optical disc while improving its jitter troubles. SOLUTION: A continuous single signals of the 3T which becomes an additional information recording area is recorded in advance on an optical disc as pre-master signals (S100). When recording additional information, the access position of the recording laser beam is controlled targeting on the pre-master signal recorded area on an optical disc PD (S102). While the recording pulses 98T are off, the 3T signals are read and a revolution servo is applied (S104). When the revolution servo is stabilized, a laser beam is radiated to the single bit row 3T signals pre-recorded to add additional information (S110). COPYRIGHT: (C)2003,JPO

CONSTITUTION:An objective lens 25 is adjusted in a radial direction by rotating a holder of the lens 25 in a biaxial actuator 25a. Besides, the lens 25 is adjusted in a tangential direction by rotating the actuator 25a and a skew base 23 around a horizontal shaft 22. By rotating an adjusting screw 29 of a rotation adjusting means 24, in other words, the gap between an optical base 23 and the base 23 in this area is adjusted, while a tilt is adjusted by rotating the base 23 supported rotatably around the shaft 22. According to this constitution, both the tilt of the lens 25 and a skew can be adjusted easily, the base 23 is supported only by the shaft 22 which does not need machining of high precision, the cost is reduced and unstableness in a tracking direction is prevented.

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.

Abstract: PURPOSE:To perform easily the positioning and adjustment of photodetectors and to improve detecting sensitivity by separating a part of a center part and a part of a peripheral part at least out of returning light flux from a beam splitter in different directions and guiding respective light rays to respective photodetectors. CONSTITUTION:The light flux from a semiconductor laser LD is focused like a spot on a disc D and the returning light flux reflected by the signal surface passes through an optical path reversely, turns its optical path from the deflecting beam splitter 12 to an auxiliary lens 15 side and is made incident to a space dividing half mirror 16. The light reflected on a center part 16a of the mirror 16 is made incident to a photodetector PD1 and the light passing through a peripheral part 16b is made incident to a photodetecor PD2. Consequently, the positioning of the photodetectors can be easily adjusted and the detecting sensitivity can be improved by reducing the diameter (b) of the center part 16a of the space dividing half mirror 16.
