<p>Stable and appropriate data retrieval is performed if reproduced signals vary locally because of noises or include regular distortions. This is achieved by a method of adjusting sampling values in sampling signals reproduced from a recording medium that stores data. The method comprises the steps of counting the frequencies of the levels of quantized data, drawing a histogram based on the count, and retrieving accurate data by means of the frequency distribution of the levels in the histogram.</p> |
