摘要： PROBLEM TO BE SOLVED: To stabilize an adjacent track servo(ATS) for preventing a problem that recording mark strings overlap with each other caused from displacement of spots accompanying with lens shift and the like while recording on an optical disk recording medium which includes a reference plane having positional guide elements formed thereon and a recording layer formed at a depth position different from the reference plane.SOLUTION: The recording apparatus employs a configuration in which a tracking servo loop is formed as a minor loop for controlling objective lens based on the positional guide elements on the reference plane and a servo control signal is provided to the loop by an ATS control system. The ATS control system is configured to perform phase compensation so as not to generate a peak in a transmission characteristic gain of an ATS loop such as whole integration, a primary LPF or the like. Also, the control band of the minor loop is set in a band which is sufficiently higher than the control band of the ATS loop. With this, a peak is prevented being generated in the loop transmission characteristic gain, which conventionally occurs when only the ATS is used; thus the dispersion of tracking error is prevented resulting in a stabilization of the servo.

摘要： PROBLEM TO BE SOLVED: To increase recording capacity by increasing the recording density of marks on a recording layer of an optical recording medium having a reference plane, which carries information recorded by CAV system, and a recording layer formed at a depth different from the reference plane.SOLUTION: Marks are recorded on the recording layer based on recording clocks which are generated by modifying the frequency of a reference signal corresponding to radius position information recorded on the reference plane. Compared to a case where recording is simply made by CAV on the recording layer according to the rotation of an optical recording medium driven at a constant speed, the recording density of marks on the recording layer is increased by carrying out the mark recording based on the recording clocks in which the frequency is modified in accordance with the radius position.

摘要： PROBLEM TO BE SOLVED: To provide an optical drive device and a signal generation method which can accurately detect amplitude values at pit and mark parts, with respect to an optical recording medium on which pits or marks are position recorded, even when sampling timing indicated by a clock relatively varies due to the influence of jitters of reproduction signals and the like.SOLUTION: Reproduction signals are sampled at leading edge timing and trailing edge timing of a pit or a mark, and the sampling values are averaged. Averaging the sampling values sampled at both of the leading and trailing edge timing prevents detected amplitude values (namely, the values obtained by the averaging) from varying even when the sampling timing indicated by a clock varies with the reproduction signals. That is, the same amplitude value can be properly detected for a part where the same amplitude value is to be detected normally.

摘要： PROBLEM TO BE SOLVED: To improve accuracy of correcting shift of a spot of first light for recording data on a bulk layer and second light to be used for positional control when correcting the spot shift by applying the first light and the second light to an optical disk recording medium having the bulk layer and a reference surface having positional guide pieces (pit strings).SOLUTION: A reference track is formed at a position in a bulk layer, which is the same radial position as that of a predetermined pit string in the reference surface. In addition to this, while the reference track is subjected to tracking servo with the first light, an amount of shift of the second light from the reference track and an amount of generated causal events are detected, and a correction coefficient supposed to be proper is calculated backward from the results of the detections. By calibrating the correction coefficient, the correction coefficient supposed to be proper is obtained according to a layer position where actual recording is performed, a drive device (optical system), and a difference of disks, so that the shift of an information recording position with the first light can be corrected precisely.

摘要： PROBLEM TO BE SOLVED: To provide an information reproducing device performing a Viterbi decoding method which generates state data expressing selected state transition and evaluates the quality or the like of a reproduced signal based on the state data. SOLUTION: An SMU (Status Memory Unit) 134 is used instead of a PMU (Pass Memory Unit) in a Viterbi decoder. The SMU 134 has four status memories 150, 151, 152 and 153 each having a state data value of a plurality of bits expressing the state as a processing unit and forms four status data as series of status data values by each status memory. A merge block 135 forms decoded data based on the four status data, detects disagreement between the four status data and forms a disagreement detection signal NM. The disagreements are counted based on the disagreement detection signal and quality of the decoded data or the reproduced signal is evaluated based on the counted value. COPYRIGHT: (C)2008,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To achieve recording in an appropriate servo state by reducing residue of rotation frequency left due to a difference between recording light and adjacent servo light in circumferential position in adjacent track servo.SOLUTION: For the adjacent track servo, the recording device emits recording light for recording a mark on a recording layer, and also emits adjacent servo light (ATS light) for adjacent track servo by which a constant distance in a disk radial direction is kept from the light, with an emitting position being different from the position of recording light in a disk circumferential direction. In this case, as a servo error signal based on a receiving light signal for the adjacent servo light, the recording apparatus obtains a correction servo error signal to be obtained when the adjacent servo light is emitted at a position in the disk circumferential direction that is the same as recording light. Using the correction servo error signal, the recording apparatus generates a tracking servo signal and carries out a tracking servo.
