    Abstract: The optical data recording method comprising the steps of: modulating data to be recorded, to generate a plurality of recording modulation codes; and emitting a pulse-like light beam to an optical disc, so that a plurality of recording marks and spaces which have lengths corresponding to the plurality of recording modulation codes are formed on the optical disc. In the optical data recording method, at least two of the plurality of recording marks comprises: a first pulse which is disposed at a front and forms a leading edge of the recording mark, a last pulse which is disposed at a backend and forms a trailing edge of the recording mark, and a multi-pulse train which is disposed between the first pulse and the last pulse and forms a center of the recording mark. The multi-pulse train has a pulse period longer than T which represents a reference period of the recording modulation code.

    Abstract: A method of determining an optimum recording power with respect to a rewritable optical recording medium with multiple layers. The method includes the operations of writing a recording signal to an unrecorded area of a power calibration area (PCA) of the rewritable optical recording medium using a predetermined recording power, and measuring characteristics of the recording signal, determining whether the measured recording signal characteristics have a saturation area, computing a recording power at a saturation point of the recording signal characteristics when the recording signal characteristics have the saturation area, and determining an optimum recording power by multiplying the recording power at the saturation point by a predetermined value. An optimum recording power is determined by using the saturation point of the recording signal characteristic curve such that optimum recording power can be accurately obtained when the optimum recording power is in the saturation area.

    Abstract: An information recording medium that can be rapidly finalized, and a recording/reproducing apparatus and method using the same are provided. In the information recording medium, a prepit is pre-formed in a finalization area. Since the portion that has to be filled with data in finalizing the information recording medium is previously formed as the prepits series in manufacturing the information recording medium, the time necessary to finalize the information recording medium can be shortened, thereby achieving the rapid finalization of the medium.
