SLOPE DETECTION METHOD, AND INFORMATION DETECTION/WRITING APPARATUS USING THE METHOD

摘要

Disclosed is a method of detecting a slope of a surface of an information record medium in an apparatus for detecting/writing information using one or a plurality of probes from/in the information record medium, comprising, scan step of scanning the surface of the information record medium using the probe, information detection step of detecting information from the surface of the information record medium through said probe when the scan step is executed; and slope detection step of detecting the slope of the surface of the information record medium on the basis of the information detection result.
