    摘要: An 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, wherein 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, wherein the recording pulse train includes a multi-pulse area in which the multi-pulse train disposed, a position of at least one pulse of the recording pulse train in the multi-pulse area is set so that a multi-pulse duty is set at a predetermined value, the multi-pulse duty being obtained by dividing a pulse width of the multi-pulse train by a period of the multi-pulse train, and the multi-pulse train has a pulse period which is twice as large as a reference period T of the recording modulation code and a corresponding device.

    摘要: An optical recording medium (101) is disclosed that allows information to be recorded and played back properly, even when a type of recording medium in which information is recorded to grooves is used along with a type of recording medium in which information is recorded to lands, as well as a method for recording and playback with this medium. Recording track information is recorded in advance, indicating whether information is to be recorded in the grooves or the lands, whichever of the grooves and lands is best suited to the recording of information is selected on the basis of the recording track information that is read out, and the recording or playback of information is performed.

    摘要: An optical disk apparatus performing either one of recording and reproduction of an optical disk in which groove-shaped groove tracks and land tracks present between the groove tracks are alternately connected to each other in a spiral shape, includes: a recording and reproduction unit for recording a signal in at least one continuous groove track and at least one continuous land track, and then reproducing the signal from the groove track and the land track; a detector for detecting a quality of the signal recorded and reproduced by the recording and reproduction unit; a control parameter setting unit for setting a control parameter related to at least one of the recording and the reproduction of the optical disk; and a controller for changing the control parameter set by the control parameter setting unit, repeating the recording and reproduction performed by the recording and reproduction unit and detection performed by the detector every time the control parameter is changed, and determining the control parameter based on the quality of the signal detected by the detector.
