摘要： An information recording method is provided, which comprises the steps of (a) determining a power level of a pulse sequence, (b) generating the pulse sequence based on the power level determined, and (c) irradiating an information recording medium with light corresponding to the pulse sequence generated to record information represented by at least either a recording mark or a space onto the information recording medium. The pulse sequence comprises a multi-pulse chain for forming the recording mark. The multi-pulse chain comprises a plurality of pulses having a peak power level. In the step (a), a bottom power level is determined between the peak power level and an erase power level which is lower than the peak power level while keeping an interpulse spacing constant.

The present invention includes the steps of generating a pulse train including a first pulse and a second pulse and forming at least one of a recording mark and a space onto an information recording medium by irradiating the pulse train onto the information recording medium while rotating the information recording medium at a certain linear velocity. The first pulse is a pulse for forming a central portion of the recording mark, among the recording mark and the space. The second pulse is a pulse for forming a portion other than the central portion of the recording mark, among the recording mark and the space. The step of generating the pulse train includes a step of determining a power level of the first pulse in accordance with the linear velocity and a power level of the second pulse.

摘要： The operating and other procedures of a disk or recording medium application system of the type for which a network is used are simplified. Disks or recording media have auxiliary data recording areas, where different IDs for individual disks, and/or cipher keys and/or decoding keys for ciphers are recorded in advance in a factory. By using the IDs to release the soft ciphers, using the cipher keys when sending the ciphers, and using the decoding keys when receiving the ciphers, user authorization procedures are simplified.

摘要： An optical recording/reproducing apparatus forms multiple marks with nine mutually different lengths, which are represented as 3T through 11T according to an eight-to-sixteen modulation coding technique, in an information layer of a rewritable information carrier by irradiating the information layer with a pulsed radiation beam. A test mark with a length equal to or greater than 7T is once recorded in the information layer, a signal associated with the test mark is read out and then an average power of the pulsed radiation beam is corrected to uniformize the widths of marks with various lengths of 7T more. This correction may be performed by partially increasing the power of the radiation beam represented as a multi-pulse train.

摘要： When data is reproduced by an apparatus which is different from an apparatus used for recording the data, the fluctuation of edge positions of the reproducing data increases, making reproduction incompatible, and the present invention solves this problem. The present invention comprises reproducing learning means 13 and 24 for switching a frequency characteristic of the reproducing system, which detects the changes of the local optical constant, to a predetermined frequency characteristic, and recording learning means 20 for correcting the start edge or end edge position of the recording pulse for each combination of length of a mark block and length of the preceding or subsequent space, so that the edge position of the binarized reproducing data comes to a desired position, and since the frequency characteristic of the reproducing system is unified before learning the edge shift amount caused by the thermal interference between marks, the length of the recorded marks and spaces can always be constant, which improves the reproducing compatibility among reproducing apparatuses.
