Abstract
In an information recording medium recording method, recording is interrupted, in recording on an information recording medium, when a predetermined interruption condition is met. A signal recorded in a recorded area is played back and a recording signal playback waveform signal is obtained. Error information indicating an error between a reference waveform signal derived by partial response equalization of a data string and the recording signal playback waveform signal is obtained. A recording condition is corrected on the basis of the error information. A recording/playback apparatus and information recording medium are also disclosed.
