Abstract: AN OPTIMUM PERFORMANCE IS ACHIEVED RELATIVE TO WRITE-ONCE TYPE OPTICAL RECORDING MEDIUMS ON WHICH INFORMATION IS RECORDED BY MEANS OF A BLUE-VIOLET SEMICONDUCTOR LASER. AN OPTICAL DISC RECORDING/REPRODUCTION APPARATUS (10) COMPRISES AN LD CONTROL SECTION (17) ADAPTED TO CONTROL THE IRRADIATION POWER OF A LASER WHEN WRITING DATA. IF THE CYCLE OF THE CHANNEL CLOCK IS T, WHEN FORMING A RECORDING MARK HAVING A LENGTH OF N ´ T (N BEING AN INTEGER NOT SMALLER THAN 2), A PULSE BEAM IS IRRADIATED ONTO THE WRITE-ONCE TYPE INFORMATION RECORDING MEDIUM (1) FOR NL2 TIMES (DECIMALS, IF ANY, BEING TO BE ROUNDED DOWN). WHEN FORMING A RECORDING MARK HAVING A LENGTH OF NOT SMALLER THAN 6T AND EVEN NUMBER TIMES OF T, A PULSE BEAM IS IRRADIATED FOR N/2 TIMES WITH ALL THE INTERMEDIATE PULSE BEAMS SYNCHRONIZED WITH THE PHASE OF THE CHANNEL CLOCK EXCEPT THE LEADING PULSE BEAM AND THE TAIL END PULSE BEAM. WHEN FORMING A RECORDING MARK HAVING A LENGTH OF NOT SMALLER THAN 6T AND ODD NUMBER TIMES OF T, A PULSE BEAM IS IRRADIATED WITH ALL THE INTERMEDIATE PULSE BEAMS DELAYED FROM THE PHASE OF THE CHANNEL CLOCK BY T/2 EXCEPT THE LEADING PULSE BEAM AND THE TAIL END PULSE BEAM.

Abstract: An optimum performance is achieved relative to write-once type optical recording mediums on which information is recorded by means of a blue-violet semiconductor laser. An optical disc recording/reproduction apparatus 10 comprises an LD control section 17 adapted to control the irradiation power of a laser when writing data. If the cycle of the channel clock is T, when forming a recording mark having a length of n × T (n being an integer not smaller than 2), a pulse beam is irradiated onto the write-once type information recording medium for n/2 times (decimals, if any, being to be rounded down). When forming a recording mark having a length of not smaller than 6T and even number times of T, a pulse beam is irradiated for n/2 times with all the intermediate pulse beams synchronized with the phase of the channel clock except the leading pulse beam and the tail end pulse beam. When forming a recording mark having a length of not smaller than 6T and odd number times of T, a pulse beam is irradiated with all the intermediate pulse beams delayed from the phase of the channel clock by T/2 except the leading pulse beam and the tail end pulse beam.
