ABSTRACT:
An information recording and reproducing apparatus for reproducing information recorded on a recording medium by two-dimensionally scanning the surface of the recording medium with a probe electrode includes a detector to detect data indicative of the surface information of the recording medium by using a physical interaction which occurs between the probe electrode and the recording medium, another detector to detect predicted data to predict the surface information of the recording medium from the data by using predetermined predictive parameters, and a reproducing unit to reproduce the information recorded on the recording medium by using the data and the predicted data, for example, on the basis of the difference between them. The apparatus also has a learning unit to optimize the predictive parameters on the basis of the data and the predicted data.
