Abstract
In a method for performing magnetic recording and reproducing an apparatus is used which includes a magnetic head carried by a piezo-electric movable element, the position of the magnetic head is detected such that reproduction signals are maximized within the range of transverse movement of the magnetic head, i.e., the range of less than 1/3 of the track width is detected. Their corresponding pattern signals are inputted as renewed successively. The result of this method is that a good reproduction image can be obtained even from a magnetic tape having locally different record levels, following any track curvature change with time, without deteriorating the quality of image during reproduction.
