間に設けたことを特徴とする磁気デイスク装置。 In a magnetic disk device in which a servo head for reading track positioning information is arranged between a magnetic recording medium and a data head for recording and reproducing information on the back side of the servo head, the core of the servo head has a magnetic field that corresponds to the locus drawn when seeking. A shield plate, which is larger in size by 4 mm or more on both sides in the radial direction and both sides in the rotational direction of the recording medium and is formed by laminating Mn--Zn ferrite and a copper plate, is placed between the core of the servo head and the data head. A magnetic disk device characterized by being provided with.
