    Abstract: PROBLEM TO BE SOLVED: To increase recording density and recording capacity by making it possible to reproduce recording information even when a track pitch is set beyond an optical threshold.SOLUTION: In a recording medium, simple tracks and tracks with grooves are alternately arranged in a radial direction at a track pitch of 0.27 μm or less, the simple tracks being formed from an arrangement of pit or marks, and the tracks with grooves being such that a groove is inserted between the pits or marks. Thereby, a tracking error signal almost the same as with the case where a track pitch two times as equal as the actual track can be obtained, and tracking servo can be applied steadily. At this time, the application of the tracking servo for the simple tracks with no groove and the tracks with grooves can be achieved by switching between positional control based on a signal in which the polarity of a tracking error signal is inverted or offset and positional control based on a signal in which the polarity of a tracking error signal is inverted or offset, according to whether a target of positional control is a simple track or a track with a groove.

    Abstract: PROBLEM TO BE SOLVED: To shorten a start time and also improve the recording quality.SOLUTION: A recording and reproducing unit (11) alternately repeats a recording operation of converting recording data to recording pulses (WP) on the basis of recording parameters and forming a recording area on an optical disk (10) on the basis of the recording pulses (WP) and a reproducing operation of generating an analog reproduction signal (AS) on the basis of the recording area formed on the optical disk (10) by the recording operation. A reproduction processing unit (12) converts the analog reproduction signal (AS) to a digital reproduction signal (DS). A decoding processing unit (13) subjects the digital reproduction signal (DS) to a maximum-likelihood decoding process to generate a binary signal (D302). A quality information detection unit (14) detects a reliability value for each edge pattern of the binary signal (D302). A control unit (15) adjusts the recording parameter on the basis of the reliability value detected for each edge pattern.

    Abstract: PROBLEM TO BE SOLVED: To provide a preferable patterned media structure and a recording/reproducing method if recording/reproducing in a near-field method is performed on a patterned medium.SOLUTION: By forming a wobbling track aside from and alongside a track which is a recording/reproducing target, by irradiating the wobbling track with wobbling track light which is different from recording light, by using reflected light of the wobbling track light to generate a gap-length error signal and perform gap-length servo, the gap-length error signal can be generated without an influence of reflected light of the recording light. As a result, it is possible to prevent a complicated and high-cost configuration of an optical system in irradiation of exclusive light having a different wavelength from that of the recording light and in separation detection of reflected light of the exclusive light. By providing the wobbling track, it is also possible to generate a tracking error signal using the wobbling track, to reproduce address information, and to generate a clock using the wobbling track while preventing a complicated PLL circuit.
