发明名称 Information reproducing method and information reproducing apparatus which uses the method.
摘要 <p>In a reproducing operation, scanning information is detected while scanning an information string with a probe such that a density of the scan lines is higher than a density of the recorded information, and a logical-sum signal of the plurality of scanning information is used as a reproduced signal. It is thereby possible to prevent deterioration during information processing of the S/N ratio and the like produced due to a positional error of a recording-medium control mechanism caused by various factors. <IMAGE></p>
