Abstract

PURPOSE:To prevent the generation of Barkhausen noise by forming a shunt bias conductor film from a permanent magnet film made from a hard magnetic metallic film magnetized in the core width direction of a magneto-resistance effect element. CONSTITUTION:On a signal detecting part 21a of an MR element 21 in place of a shunt bias conductor film such as a conventional Ti, a hard magnetic metallic film 22 composed of a Co-Ni, Co-P, etc., is directly joined, and on pullout terminals 21b and 21c of both edges of the detecting part 21a, a non- magnetic conductor film 23 composed of Ca is directly joined. The above- mentioned hard magnetic metallic film 22 is magnetized in the core width W direction of the MR element 21 and constituted as a permanent magnetic film 24. By such a constitution, since the permanent magnetic film 24 is directly joined on a signal detecting part 21a of the MR element 21, it is not necessary to enlarge the residual magnetization of the permanent magnetic film 24, the impression of the bias magnetic field to linearly operate the permanent magnet film and the impression of the magnetic field in the core width W direction of the MR element 21 by the permanent magnetic film 24 can be executed.

Shunt bias type magnetoresistive playback head (
An MR head (hereinafter referred to as an MR head) is a magnetic head that uses a shunt bias conductor and a magnetoresistive element (hereinafter referred to as an MR element), and the electrical resistance value of the MR element changes depending on the strength of the medium magnetic field. Utilizing the characteristics, a constant current (
By supplying a sense current (sense current), the magnetic field generated by the current flowing through the shunt bias conductor film is applied as a bias magnetic field that operates the MR element at an appropriate bias point, and the magnetic field is applied in the direction of the hard axis perpendicular to the axis of easy magnetization. This system detects the change in resistance of the MR element due to the medium signal magnetic field as a voltage change, and is attracting attention as a read head that does not depend on the running speed of the recording medium and can provide a large output.

Since the resistance change of the MR element is caused by the rotation of the magnetization vector, in order to obtain a stable output, it is necessary to control the magnetic domain structure of the MR element so that the magnetization vector rotates smoothly. From this point of view, a single magnetic domain structure is most desirable as a domain structure.

By the way, a magnetoresistive film (M
R films) are generally given induced magnetic anisotropy by a film formation method in a magnetic field so that the axis of easy magnetization points in the core width direction, but as recording media become more densely recorded, the track becomes narrower. As the core width of the MR head becomes smaller, the demagnetizing field in the core width direction increases, so the magnetic domain structure of the MR film is disturbed and many magnetic domains are formed.

Therefore, during reproduction, reproduction waveform distortion called Barkhausen noise due to such irregular movement of the magnetic domain wall of the MR element appears in the reproduction output, which tends to significantly deteriorate the reproduction signal quality. Therefore, it is desired to improve the quality of the reproduced signal by suppressing the occurrence of such Barkhausen noise.

By applying a magnetic field in the direction of the core width W to the MR element I5 using these two magnetized hard magnetic films 16 and 17, the irregular movement of the domain wall is caused by narrowing the core width of the MR element 15. This eliminates the occurrence of Barkhausen noise.

The distance from 17 was set to 2 due to the relationship between film formation technology
It is difficult to reduce the core width to 3 μm or less, and when the core width W is added, the core width inevitably becomes larger, resulting in a disadvantage that a sufficient magnetic field cannot be applied to the MR element 15.
