    摘要： Making thinner the magnetic domain control layer deteriorates the magnetic properties. Also, disturbances tend to increase the magnetization dispersion of the magnetic domain control layer, thereby lowering the magnetic domain control bias magnetic field. In one embodiment of the invention, a first magnetic domain control layer is provided in the proximity of the free layer of the GMR sensor in such a way that the track width is Twr1. Outside the first magnetic domain control layer is provided a second magnetic domain control layer. The second magnetic domain control layer placed outside the first magnetic domain control layer gives the first magnetic domain control layer an external bias field. The amount of magnetization of the tip of the first magnetic domain control layer is polarized and increased by the bias magnetic field from the second magnetic domain control layer. This causes the first magnetic domain control layer to apply a strong bias magnetic field having a lower dispersion to the free layer of the GMR sensor.

    摘要： Even if the track and gap widths are made narrow in a read head, a narrow track head has so far been unable to afford satisfactory off-track characteristics because of a wide shield spacing over electrodes. The invention provides a magnetic head wherein, in the height direction of a magnetoresistive element, the spacing between an upper magnetic shield and a lower magnetic shield at an air bearing surface is narrower than the spacing between the upper and lower magnetic shields formed over a thickest portion of each of electrodes in contact with associated magnetic domain control layers.

    摘要： Making a geometric track width small does not decrease a read track width, resulting only in an output being reduced. In one embodiment, a seed layer, an underlayer, and a magnetic domain control layer are laminated on both sides of a magnetoresistive sheet unit. A lower electrode film is thinly formed on an upper portion of the magnetic domain control film. A portion of the lower electrode film near the magnetoresistive sheet unit does not protrude substantially from an upper surface of the magnetoresistive sheet unit. Should the portion protrude, a step from the upper surface of the magnetoresistive sheet unit is about 14 nm or less. This portion and the upper surface of the magnetoresistive sheet unit are formed into a flat surface. An upper electrode film is formed thickly on an upper portion of the lower electrode film on an outside thereof so as to circumvent the flat surface. A protective layer, an upper gap film, and an upper magnetic shield film are also formed.
