In one embodiment, a differential-type magnetic read head includes a differential-type magneto-resistive-effect film formed on a substrate, and a pair of electrodes for applying current in a direction perpendicular to a film plane of the film. The film includes a first and second stacked film, each having a pinned layer, an intermediate layer, and a free layer, with the second stacked film being formed on the first stacked film. A side face in a track width direction of the film is shaped to have an inflection point at an intermediate position in a thickness direction of the film, and the side face is shaped to be approximately vertical to the substrate in an upward direction of the substrate from the inflection point. Also, the side face is shaped to be gradually increased in track width as approaching the substrate in a downward direction of the substrate from the inflection point.

Provided is a differential type reproduction head which can obtain a preferable bit error rate without causing a baseline shift even when two magnetoresistive elements have different maximum resistance change amounts. The differential type reproduction head has a layered structure formed by a first magnetoresistive element having a first free layer, a differential gap layer, and a second magnetoresistive element having a second free layer. When DR1 and DR2 are the maximum resistance change amounts of the first magnetoresistive element and the second magnetoresistive element, respectively, HB1 is a magnetic domain control field applied to the first free layer, and HB2 is a magnetic domain control field applied to the second free layer, the following relationships are satisfied: HB1>HB2 when DR1>DR2; HB2>HB1 when DR2>DR1.

A magnetic recording read head is provided capable of achieving high reproduction output, resolution, and SNR, even at a high linear density. There is also provided a magnetic recording and reproducing device capable of achieving sufficient error bit rate. The magnetic recording read head includes a differential read head and a write head. The differential read head has a multilayer structure formed by laminating a first magnetoresistive sensor having a first free layer, a differential gap layer, and a second magnetoresistive sensor having a second free layer. Outside the multilayer structure, a pair of electrodes and a pair of magnetic shields are provided respectively. A ratio (Gl/bl) of an inside distance (Gl) between the first and second free layers to a bit length (bl) is set to 0.6 or more and 1.6 or less.
