| 摘要 |
There is disclosed an optical information recording/reproducing apparatus capable of exactly detecting a timing to interrupt recording or reproducing. A threshold value is set with respect to a state detection signal (parameter) indicating an irradiation state with an optical disk 1 such as a focus error signal and a tracking error signal, and the recording or reproducing is interrupted in accordance with a comparison result of the state detection signal with the threshold value. The threshold value set with respect to one state detection signal is set in accordance with another state detection signal.
