Optical disc apparatus and a recording method

To regenerate the recorded area when the recording operation interruption, if the deterioration of the recording signal by the signal quality detection means (16) is detected (S4, S5), performed tilt adjustment in a recorded area (S6 ), it detects the signal quality of the recording signal after the tilt adjustment (S6), when still in a degraded state adjusts the recording parameter (S7). It is not necessary to obtain the tilt adjustment value at a plurality of radial positions for tilt correction in advance, overhead apparatus is reduced, the recording quality is improved.
