发明名称 Tracking control circuit and method.
摘要 <p>In a tracking control circuit for a rotary head type magnetic recording/reproducing apparatus, the feed speed of the magnetic tape (13) is controlled in response to an average value of plural tracking error information data detected from at least two or more locations on a recording track, whereby a tracking error can be corrected with high accuracy even when the plural tracking error information data are reproduced at unequal intervals. &lt;IMAGE&gt;</p>
