Abstract: PROBLEM TO BE SOLVED: To improve an SNR of an optical detection processing circuit including a photodetector more than in the conventional practice in a reproducing device adopting a homodyne system.SOLUTION: A first current-voltage conversion part for performing current-voltage conversion for first combined current obtained by combining output current from a cathode of a first PD (photodiode) with output current from an anode of a second PD by connecting a cathode of the second PD to an anode of the first PD, and a second current-voltage conversion part for performing current-voltage conversion for combined current obtained by combining output current from the anode of the first PD with output current from the cathode of the second PD are provided. A differential signal generating part for generating a differential signal between an output by the first current-voltage conversion part and an output by the second current-voltage conversion part is also provided. Since the reproduction signal can be acquired by using not only the combined current of the output current of the anode of the first PD and the cathode of the second PD but also the combined current of the output current of the cathode of the first PD and the anode of the second PD, a reproduction signal level can be increased and the SNR can be improved.

Abstract: PROBLEM TO BE SOLVED: To provide a recording device which can reproduce an accurate clock signal, for accurately recording information, a recording method, a reproducing device which can reproduce the accurate clock signal, for accurately reproducing information, a reproducing method, and a recording medium.
SOLUTION: In the recording device 1, the layer (reference plane) R of an optical disk 10 is irradiated with a red laser beam Lr (ST501), and the reflected beam of the red laser beam Lr on the layer (reference plane) R is converted into an electric signal by a photodetector 35 and the electric signal is output to a record data output part 13. Thus, the reflected beam on the layer (reference plane) R of the red laser beam Lr is reproduced separately from a reflected beam from a recording layer 51 or the like. As a result, an accurate electric signal is generated from the reflected beam from the layer (reference plane) R of the red laser beam Lr by the photodetector 35. Thus, based on the accurate electric signal, a clock signal used for recording information is accurately reproduced by a phase synchronizing circuit 42 (ST502).

Abstract: PROBLEM TO BE SOLVED: To precisely record or reproduce a hologram showing information on an optical disk. SOLUTION: When recording information on an optical disk 100, this disk drive makes the focusing point Fr follow the desired track by controlling the position of the objective lens OL1 based on the result of detecting the reflected red light beam Lr2, and moves the focusing point Fb1 of the blue light beam Lb1 to the desired mark position by the objective lens OL1. Further, it moves the focusing point Fb2 to the desired mark position by controlling the objective lens OL2 based on the result of detecting the blue light beam Lb1 through the objective lenses OL1 and OL2. Since the focusing point Fb1 of the blue light beam Lb1 and the focusing point Fb2 of the blue light beam Lb2 can be moved to the same mark position to interfere with each other, it can record the recording mark RM on the desired mark position.

Abstract: PROBLEM TO BE SOLVED: To record a hologram with uniform intensity over the whole recording area of a holographic recording medium in the case of recording a hologram on a plate-form holographic recording medium by generating a conical reference optical beam by using a conical optical member, and irradiating the recording medium with the conical reference optical beam and a recording optical beam. SOLUTION: The effect that the power density of the reference light has a radial directional position dependence on a holographic disk 12 is compensated by using a light beam partial light shielding means 40. Or, the power density of the reference light on the holographic disk 12 is prevented from having the radial directional position dependence by determining appropriately the relative arrangement position between the holographic disk 12 and a conical optical member such as a conical convex mirror 56 or a conical prism 62.

Abstract: PROBLEM TO BE SOLVED: To effectively protect the profit of a copyright holder by preventing copyright protection information recorded in an optical recording medium from being recognized with ease. SOLUTION: Signals based on multiple series and obtained by disturbing copyright protecting information SA using a plurality of binary series are recorded in a prescribed region of the optical recording medium. Since the copyright protection information SA can be deciphered unless a plurality of the binary series used for disturbance are known, an encoding process can be performed by using the information as a key. At the time of reproduction, the copyright protection information SA is decoded by performing correlation operation between reproducing signals and a plurality of the binary series the same as a plurality of the binary series used for disturbing the information when the copyright protection information SA is recorded using a plurality of binary series and then the encoding process performed to the recording information using the information is released.

Abstract: PROBLEM TO BE SOLVED: To effectively avoid a bit error due to cross-talk through application to, for example, an optical disk apparatus and an optical disk, relating to an information recording apparatus, an information recording method, an information recording medium, an information reproducing apparatus, and an information reproducing method. SOLUTION: Modulation reference signals SC1 to SC6 are generated so that between adjacent laser beam scanning traces, the modulation reference signals SC3 and SC5 to be used for modulation become substantially orthogonal to each other and the modulation reference signals SC4 and SC6 to be used for modulation become substantially orthogonal to each other. Thus, between the adjacent laser beam scanning traces, by generating the modulation reference signals so as to be in a substantially orthogonal relationship, a bit error due to cross-talk can be effectively avoided.

Abstract: PROBLEM TO BE SOLVED: To make reproducible data even without recording a synchronizing signal showing a bit boundary in modulating a carrier signal and reproducing the data recording according to the change of a scan locus by generating a recording signal so as to repeat the same signal waveform in a cycle being shorter than the cycle of a bit boundary of input data. SOLUTION: An optical disk drive 1 records output data of an information source 3 on a master disk 2. In such a case, a data processing circuit 9 converts output data DINFO of the source 3 into 4-bit parallel data DD0 to DD3. A record signal generation circuit 10 generates a recording signal RS so as to repeat the same signal waveform in a cycle being shorter than the cycle of the bit boundaries of the data DD0 to DD3 between periods corresponding to 1-bit of the data DD0 to DD3 in the signal RS. An optical modulator 7 controls a laser beam L0 and emits a laser beam L1 whose light quantity changes in accordance with the signal RS.
