    摘要： A magneto-resistance effect head records and reproduces recorded magnetic material. The magneto-resistance effect head has a magneto-resistance effect film connected to a pair of leads. Additionally, a magnetic yoke, with a first and second magnetic yoke member, directs a signal magnetic field from a recording medium to the magneto-resistance effect film. The magneto-resistance effect head is constructed such that the first and second magnetic yoke members have surfaces that face the recording medium. The surfaces of the first and second magnetic yoke members have a magnetic gap between them. Additionally, the magneto-resistance effect film is recessed from the medium facing surfaces by a predetermined distance. Moreover, the first and second magnetic yoke members are aligned almost in parallel with the magnetic flux flow from the recording medium to the first magnetic yoke member, the magneto-resistance effect film, and the second magnetic yoke member.
