Abstract: PROBLEM TO BE SOLVED: To decode copyright information recorded based on a very small change in the edge position of a pit within a short time by reducing the number of integrating times.
SOLUTION: An intercode interference amount is calculated according to a pit pattern input from a Viterbi decoder 5 and recorded in an optical disk 1, and the intercode interference amount is eliminated from a reproducing signal obtained from an equalizer circuit 4. As a copyright information detector 9 decodes copyright information from the reproducing signal reduced in noise (intercode interference amount is regarded as noise), the number of integration samples necessary for decoding is reduced, and the copyright information is decoded within a short time.

Abstract: PROBLEM TO BE SOLVED: To effectively avoid the lowering of recording density and to detect precisely the reproducing reference of information by correcting the phase of a reproducing reference signal so that the phase difference between a carrier signal in a regenerative signal and the reproducing reference signal has a pre scribed phase difference. SOLUTION: The phase of the reproducing reference signal REF is corrected so that the phase difference between the carrier signal incorporated in the regenerative signal SU2 and the reproducing reference signal whose REF becomes a prescribed value. When the precision of the reproducing reference signal REF is improved than a synchronizing signal SYNC according to the processing result of the regenerative signal SU2, the generation of the reproducing reference signal REF based on the synchronizing signal SYNC is switched to the generation of the reproducing reference signal REF based on the reproduced result. Thus, an optical disk device 1 detects the phase difference between a sine wave signal incorporated in the regenerative signal SU2 and the reproducing reference signal REF, and corrects the phase of the reproducing reference signal REF so that the phase difference becomes a prescribed value.

Abstract: PROBLEM TO BE SOLVED: To make it possible to evaluate quality of an optical disk without being influenced by recording conditions. SOLUTION: In this optical disk evaluation device, an optical disk 2, on which a spiral groove is formed, is irradiated with a laser beam by condensing it as a light spot by an optical pickup 4, and the light spot reflected or diffracted by the optical disk 2 is converted into an electric signal, and the quality of the optical disk 2 is evaluated from the electric signal thus obtained. In this case, it become possible to evaluate a characteristic of a recording medium without being influenced by recording conditions like a bit size, etc., by controlling the spot center controlled by the optical pickup 4 so that the center passes above the groove wall.

Abstract: PURPOSE:To enable a high density recording to be excuted by forming periodically a reference signal area and a data area in an optical disk, recording a phase reference signal as a reference signal, and adjusting fine phase deviation of a sampling clock. CONSTITUTION:Recorded data outputted from an information input circuit 1 is supplied to a conversion circuit 12 through an ECC circuit 11, and converted into data in which 3 bits make a unit. Data outputted from the circuit 12 calculates an edge position corresponding to an input data by a recording edge position calculating circuit 15, and outputted to an edge conversion circuit. A circuit 16 outputs a recorded signal to a mastering device 3 so that a pit having an edge corresponding to an input signal is formed. On the other hand, a corrected reference signal-generating circuit 14 generates a prescribed reference signal including a phase reference signal being the reference for adjusting finely phase of a sampling clock, and outputs this reference signal to the circuit 15 through a switch 13. In the device 3, A potential pit for the original disk is formed in accordance with a recorded signal outputted from the circuit 16.
