    Abstract: PURPOSE: To enable recording at a higher density. CONSTITUTION: The learning data generated by a learning data generating circuit 2 is recorded on a disk 5 and is reproduced in actuality by a player 6. The inter-symbol interference in the learning data is measured in an inter- symbol interference measuring section 21. The preemphasis correction value corresponding to the measured inter-symbol interference is calculated in a preemphasis correction value calculating section 22. The result of the calculation is recorded as a table of a ROM 18 of a recording edge position calculating circuit 17. This recording edge position calculating circuit 17 processes the recording data outputted by an information source 1 in correspondence to the table recorded in this ROM 18.

    Abstract: PURPOSE:To reduce the read-out error rate by correcting a ticking width of an interval of each edge position generated at a leading edge and a trailing edge at the time of recording, converting inversely at the time of reproducing in accordance with correction at the time of recording, and improving recording density by utilizing dispersion of a margin at the time of multi-valued recording. CONSTITUTION:An error correcting code is added to digital data inputted to an encoder section 2 by an ECC circuit 4, and converted to data of 3 bits unit by a conversion circuit 5. A system control signal is inserted from an addition circuit 6 every time when the data is sent out with time division and sent out to a calculating circuit 7, data of 3 bits unit is assigned to edge positions of each eight steps of a leading edge and a trailing edge, recording position data is outputted to a correction circuit 8, and an edge position is corrected based on a bit length. The information is converted to an analog signal by a modulation circuit 9 and outputted. A cutting machine manufactures a disk based on this data. At the time of reproducing data of the disk, data is reversely converted by a reverse correction circuit 14 through an A/D converter 11 and the like in accordance with a correction characteristic at the time of recording and outputted.

    Abstract: PROBLEM TO BE SOLVED: To provide an optical information recording medium and a reproducing apparatus that are capable of restoring address information during land reproduction as well as during groove reproduction.SOLUTION: In an optical information recording medium, continuously wobbling grooves are formed in advance to record information onto the grooves and lands abutting the grooves. Address information is recorded in the wobbles in which a plurality of modulated waves modulated with the address information are multiplexed. Each modulated wave is a fundamental wave whose frequency is a fundamental frequency of the wobbles, or a higher harmonic wave whose frequency is an integer times the fundamental frequency of the wobbles. One modulated wave is modulated with the address information regarding one of lands abutting opposite sides of a groove, and another modulated wave is modulated with the address information regarding the other of the lands abutting opposite sides of the groove.

    Abstract: PROBLEM TO BE SOLVED: To accurately record information on an optical disk wherein a hologram is formed. SOLUTION: An information recording device 60 diffracts a light beam L0 by a grating 72, and sets zeroth-order light and primary light respectively to a recording light beam LE and a servo light beam LS, condenses each beam with an objective lens 76 to form focal points FE and FS, makes the focal point FS slightly precede the focal point FE along the traveling direction of a track T, and detects a servo reflected light beam LSR to servo-control the objective lens 76, thereby allowing the servo reflected light beam LSR to follow a place where an initial hologram IH is not broken yet in a target track TG and therewith conforming the focal point FE of the recording light beam LE to a target position PG. Therefore, the initial hologram IH at the target position PG is broken to generate a recording mark RM appropriately. COPYRIGHT: (C)2010,JPO&INPIT

    Abstract: PROBLEM TO BE SOLVED: To enable improvement of reproduction accuracy of information from an optical disk. SOLUTION: An optical disk device 10 first performs focus control based on a servo detection signal U1 obtained by receiving a servo reflection light beam LSR generated by a servo light beam LS being reflected on a reference layer 102, and, after an amplitude value of a tracking error signal STE2 becomes less than a predetermined threshold, switches to focus control based on an information detection signal U2 obtained by receiving an information light beam LM3 generated by an information light beam LM1 being reflected on a target mark layer YG, thereby focus control based on the information detection signal U2 is performed reliably without significantly deviating a focus FM1 of the information light beam LM1 from the target mark layer YG, and the focus FM1 of the information light beam LM1 is adjusted to the target mark layer YG with high accuracy.

    Abstract: PROBLEM TO BE SOLVED: To increase recording density in the track direction by recording the main information in a pit and blank part, which is larger than a prescribed basic period by a multiple of a specific integer, and combining based on the output signal from a binarizing means, which compares a reproducing signal level with a threshold value, and from the detecting means of he binary signal. SOLUTION: A pit as large as the basic period and a blank part formed in the front and rear in the track direction of this pit are both made larger than the basic period by a multiple of an integer of three or more. In a binary signal integrating circuit 26, when the value of a synchronous binary signal SB1 is '0' continuously for 7 clock or more, the synchronous binary signals SB1 , for the period excluding the first and the last three clocks, replaces a synchronous binary signal SB2 to form an intermediate integrated signal. When the intermediate integrated signal value is '1' continuously for 7 clocks or more, an integrated binary signal SB4 is formed, replacing a synchronous binary signal SB3 for the period excluding the first and the last three clocks of the intermediate integrated signals, and is supplied to a decoding circuit 27.
