Abstract: Disclosed is an optical information recording medium that can solve a problem that a BCA mark becomes unrecognizable in an optical recording medium including a recording layer using an organic coloring matter. A playback signal in a burst cut area comprises a bright-area amplitude level formed upon the playback of a part where no barcode-shaped mark has been formed, a dark-area amplitude level formed upon the playback of a part where a barcode-shaped mark has been formed, and a maximum amplitude level having a protruded waveform formed upon the reproduction of the edge of a barcode-shaped mark. When a portion intermediate between the maximum amplitude level and the dark-part amplitude level is defined as an intermediate level, the intermediate level is lower than the bright-area amplitude level.

Abstract: It is an object of the present invention to provide a recording condition closer to an optimum even for a medium unknown to a drive, and more particularly to provide a method especially effective when applied to code identification methods, such as PRML, wherein codes are identified based on amplitude information of an RF signal. In order to accomplish the object, an RF signal received from a photo-receiving part 108 of a pickup is converted into sampling data by an A/D converter 300, and a Viterbi decoder 302 performs code determination using the sampling data. Codes included in a reproduction signal are then determined by synchronizing recording pulses with the reproduction signal using the result of the code determination. Then, the result is used to specify a part to be detected in the codes, and finally an amplitude of the specified part is detected.

Abstract: It is an object of certain inventive aspects to provide a recording condition closer to an optimum even for a medium unknown to a drive, and more particularly, to provide means for obtaining a preferable recording condition even for a high-speed recording in which conducting a test recording is difficult. In order to accomplish the object, a power and a phase of a recording pulse are simultaneously corrected at predetermined timing, depending on a recording speed or a recording position such as an inner or outer circumference. For instance, a phase shift ?Phase generated due to a continuing recording from an inner circumference to an outer circumference at ×2 speed is corrected simultaneously with a correction of a power shift at the timing when a recording speed is changed from ×2 to ×4. For the other recording speed, in the same manner as above, a power and a phase shift are simultaneously corrected at every time when a recording speed is changed.

Abstract: It is an object of the present invention to improve a margin to meet good recording quality by conducting a realtime correction of a recording condition of a medium with different recording characteristics for inner and outer circumferences. To accomplish the object, control factors for power and a pulse width are independently detected and corrected using an mT pulse having a length of m?T as a pulse for power control and an nT pulse having a length of n?T as a pulse for pulse width control; more specifically, power correction for mT pulse and pulse width correction for nT pulse are conducted in realtime, wherein a recording pulse stream including the mT pulse and nT pulse is irradiated onto a medium by a recording laser beam as well as pits and spaces formed by irradiation of the recording pulse stream are reproduced by a reproducing laser beam to detect the effects of power and pulse width variations independently.

Abstract: The present invention enables a recording condition closer to an optimum to be obtained even for media unknown to a drive. The present invention provides a method that is especially effective for the case where it is applied to a code identification scheme, such as PRML in which code identification is performed on the basis of information on the amplitude of an RF signal. A condition for a recording pulse comprised of a top pulse, an intermediate pulse and a last pulse is configured in a predetermined order, that is, a reference condition is first determined by a test recording involving an examination of recording quality and changes in conditions for a power and a pulse width, then a condition for the last pulse is determined by a test recording using the reference condition, and subsequently a condition for the intermediate pulse is determined using the reference condition and the last pulse.
