Abstract: There are provided an information recording medium having a power calibration area of high reliability and an information recording/reproduction device using it. The information recording medium includes a recording layer having a data area (50) for recording a user information signal, a lead in area arranged in the inner circumference of the data area (50), an inner circumference power calibration area arranged in the inner circumference of the lead in area for recording a test recording pattern, and a recording management area for recording the recording management information on the inner circumference power calibration area. In the recording layer, an outer power calibration area (70) is provided in the outer circumference of the recording end of the user information signal.

Abstract: PROBLEM TO BE SOLVED: To provide an optical data recording method optically recording data correctly even at a high transfer rate. SOLUTION: The optical data recording method mark includes a first pulse for forming a leading edge of a recording mark, a last pulse for forming a trailing edge, and a multi-pulse train for forming a center of the recording mark disposed between the first pulse and the last pulse. The multi-pulse train has a pulse period longer than T which represents a reference period of the recording modulation code. COPYRIGHT: (C)2009,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To provide a recording method for surely detecting a boundary between an unrecorded area and a recorded area when optimum power is determined by trial recording prior to recording of user data in a write-once type disk. SOLUTION: In a trial reading area of an optical disk, a light spot moves in a direction from the inner periphery to the outer periphery of the optical disk, and when the trial recording area is used from the outer peripheral side (a sector having a x mark is a recorded sector), the optimum recording power determined by trial recording in sectors 302, 303, 304, and 305 is used to perform recording in the sector 301. Thus, when next time trial recording is performed, the possibility of erroneously recognizing the recorded sectors as a unrecorded sector can be reduced. COPYRIGHT: (C)2009,JPO&INPIT
