摘要： In a composite magnetic head comprising a magnetoresistive read head (10) including a magnetic thin film having a magnetoresistive effect and soft magnetic members interposing the soft magnetic film between them through a non-magnetic insulation layer, an induction type write head (11) including poles formed in a moving direction of a medium and a conductor crossing the poles, and disposed in the proximity of the magnetoresistive head, and a substrate (5) supporting these heads, the present disclosure describes a composite magnetic head characterized in that part of a floating surface inclusive of the magnetic head constituent members has recesses (7, 8) and the read/write operations to and from the medium are effected by the portion interposed by these recesses.
