    Abstract: A data storage medium is provided on which data is to be recorded by modulating the data to generate a plurality of recording modulation codes and irradiating a pulse-like light beam to the data storage medium, so that a plurality of recording marks and spaces which have lengths corresponding to the plurality of recording modulation codes are formed on the data storage medium. At least two of the plurality of recording marks are formed by the light beam emitted according to a recording pulse train. The recording pulse train comprising 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. The plurality of recording marks have different lengths represented by T with each other. A number of pulses in each of the recording pulse trains is increased by one as the recording mark is increased in length by 2T. A shortest recording mark and a second shortest recording mark are constituted of a single pulse, respectively.

    Abstract: There is provided an optical information recording/reproducing apparatus that learns a recording power so as to determine an optimum recording condition under which the recording power is prevented from being excessively high and waveform distortion is reduced. A recording power variation circuit (12) sets variably a recording power Po in a front-end portion and a rear-end portion of a record pattern for learning a power that is output from a record pattern generation circuit (5) and a recording power Pm in an intermediate portion, while maintaining a ratio between the recording powers Po and Pm at a constant value, and data for learning a recording power are recorded. When the data for learning a recording power are reproduced, an allowable power range determination circuit (11) determines an allowable range of a recording power such that a recording power calculated by a power calculation circuit (8) using a degree of modulation detected from a reproduced signal and an allowable upper limit degree of modulation is an upper limit and a recording power calculated by an allowable waveform distortion power calculation circuit (10) using a waveform distortion amount detected from a reproduced signal and an allowable waveform distortion amount is a lower limit.

    Abstract: A DVD-R recorder according to the invention detects an item of recording speed information (d15) from a DVD-R (30) on which histories of recording speed information, write strategy, and recording power condition are stored. When the decoded item of recording speed information (d15) agrees with a set item of recording speed information (d17), the recorder detects the write strategy (d6) and the recording power condition (d10) corresponding to the decoded item of recording speed information (d15). A recording-pulse-determination section (9) converts a recording pattern (d8) into a recording pulse (d9) according to the write strategy (d6). A recording-power-determination section (12) performs an OPC based on the recording power condition (d10). The recording power condition (d10) may include information specifying that a recording pulse corresponding to the front edge of a recorded mark has a larger recording power than other recording pulses.
