The rope of this invention comprises a plurality of strands each having a twisted reinforcing fiber bundle, thermosetting resin applied to the fiber bundle, and a thermoplastic resin cover enclosing the fiber bundle. Each strand in the rope is kept to substantially a round sectional shape by the twisted fiber bundle.The method for forming the rope comprises the steps of twisting the reinforcing fibers in such a manner that the tensile strength of the twisted fibers is not reduced to less than 50% of the fibers not twisted, applying an uncured thermosetting resin to the twisted fibers, covering the fibers with a molten thermoplastic resin, cooling the thermoplastic resin to cover the fibers with solidified thermoplastic resin and thereby forming a strand, forming a rope structure from a plurality of the strands, and heating the rope structure to cure the thermosetting resin applied on the fibers.

A CPP giant magnetoresistive head includes a lower shield layer; an upper shield layer; and a giant magnetoresistive element (GMR) between the lower shield layer and the upper shield layer. The GMR includes a nonmagnetic material layer; a pinned magnetic layer; and a free magnetic layer. The pinned layer and the free layer are laminated with the nonmagnetic layer provided therebetween. A current flows perpendicularly to a film plane of the GMR, the pinned magnetic layer extends in the height direction longer than in a track-width direction and includes a first portion in the GMR. The first portion is disposed above or below the nonmagnetic layer and the free layer. A second portion is behind the nonmagnetic layer and the free layer in the height direction. The first and second portions are in the same plane. The width of the pinned layer in the track-width direction in the first portion is greater than that in the second portion.

A magnetoresistive-effect device includes a multilayer film, hard bias layers arranged on both sides of the multilayer film, and electrode layers respectively deposited on the hard bias layers. The electrode layers are formed, extending over the multilayer film. Under the influence of the hard bias layers arranged on both sides of the multilayer, the multilayer film, forming the magnetoresistive-effect device, has, on the end portions thereof, insensitive regions which exhibit no substantial magnetoresistive effect. The insensitive region merely increases a direct current resistance. By extending the electrode layers over the insensitive regions of the multilayer film, a sense current is effectively flown from the electrode layer into the multilayer film. With a junction area between the electrode layer and the multilayer film increased, the direct current resistance is reduced, while the reproduction characteristics of the device are thus improved.

The invention provides a spin valve thin film element in which output characteristics and the stability of reproduced waveforms are improved, asymmetry is decreased, and the occurrence of side reading is prevented. The spin valve thin film element includes a lamination having an antiferromagnetic layer, a first pinned magnetic layer, a nonmagnetic intermediate layer, a second pinned magnetic layer, a nonmagnetic conductive layer, a free magnetic layer, and a backed layer composed of a nonmagnetic conductive material, which are laminated on a substrate. Hard bias layers are formed on both sides of the lamination, and orient the magnetization direction of the free magnetic layer in the direction crossing the magnetization direction of the second pinned magnetic layer. Electrode layers are formed on the hard bias layers to supply a sensing current J to the lamination. The electrode layers are formed to extend to the surface of the lamination toward the central portion from both sides of the lamination.

A thin film magnetic head is able to control occurrence of Barkhausen noises attributable to configuration magnetic anisotropy of an upper shield layer. An inductive head is provided with a magnetic material layer having a space for forming a coil layer thereon. A very narrow gap is provided between a front separate layer that opposes a magnetic recording medium and a rear separate layer that opposes the front separate layer. The front separate layer serves also as an upper shield layer of an MR head and a lower core layer of the inductive head.

A through hole 5 formed in a substrate and having an electrode film on an inner surface thereof is cut and divided into two through holes or blind holes each of substantially semicircular arc shape through dicing processing using a rotating blade, and one of the-divided through holes 5 of substantially semicircular arc shape is used as an external connection terminal 3 of substantially semicircular concave arc shape thereby to form a surface mounted electronic parts having a plurality of the external connection terminals 3. The height H of the substantially semicircular arc formed at an inner surface of each of the external connection terminals is set to be equal to or smaller than a value obtained by subtracting twice a thickness t of the electrode film from a radius R of a curvature of the arc.
