Combination perpendicular magnetic head having shield material formed at both ends of an upper pole of a write element
View Patent ↗In a composite magnetic head comprising a magnetoresistive read head 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 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 supporting these heads, the present invention discloses a composite magnetic head characterized in that part of a floating surface inclusive of the magnetic head constituent members has recesses and the read/write operations to and from the medium are effected by the portion interposed by these recesses.
1. A magnetic head comprising:
a perpendicular magnetic recording head having a lower pole and upper pole; and
a reproducing head having a magnetoresistive sensor, wherein
a magnetic shield material is formed at both ends of the upper pole in a track width direction, and
a track width of the reproducing head is smaller than a track width of the perpendicular magnetic recording head.
2. A magnetic head according to claim 1 , wherein the track width of the perpendicular magnetic recording head is defined by the magnetic shield material.
