A magnetic storage device having a ramped-loading-type head suspension, in which a magnetic head slider mounted on a support beam can fly above a storage medium in stable state in the loading or unloading operation, is disclosed. The head suspension includes a support beam having a distal end and a proximal end, a gimbal pivotally coupled to the distal end portion of the support beam through a pivotal portion and a loading member connected to a free end of the gimbal positioned to the side nearer to the proximal end of the support beam. The provision of the loading member at the free end of the gimbal permits the flow-in end of a magnetic head slider mounted on the gimbal to be kept farther away from the surface of the storage medium than the flow-out end thereof, thereby eliminating an unstable flying state of the magnetic head slider.

Magnetic storage device having a head suspension

A magnetic head has a base, a magnetoresistive (MR) head section formed on the base and an inductive head section formed on the MR head section. The MR head section includes an MR element layer arranged above the base, and an operative layer involving a terminal layer and arranged above the base and laterally adjacent to the MR element layer. The major surface of the MR element layer is located in a level substantially identical to a major surface of the operative layer to form a generally even upper surface facing away from the base. Consequently, the inductive head section is provided with a generally flat recording gap layer.

Magnetic head and method for producing the same

A magnetoresistive magnetic head comprises a first magnetic shielding layer formed on an underlying layer, a first nonmagnetic insulating layer formed on the first magnetic shielding layer, a magnetoresistive device formed on the first nonmagnetic insulating layer, first and second leads formed on the first nonmagnetic insulating layer to be connected to both sides of the magnetoresistive device respectively, a second nonmagnetic insulating layer formed to cover the first and second leads and the magnetoresistive device, a second magnetic shielding layer formed on the second nonmagnetic insulating layer to be positioned over the magnetoresistive device, and a resistor element buried in at least one of the first and second nonmagnetic insulating layers to electrically connect the first lead to either the first magnetic shielding layer or the second magnetic shielding layer.
