Abstract: One embodiment of the present invention pertains to a suspension assembly comprising a suspension, a slider, and a suspension interface by which the slider is rotatably connected about a yaw axis to the suspension.

Abstract: Magnetic recording media-are provided having separately textured data and read/write head landing zones. Separating these zones on the recording surface allows independent optimization of the topology to maximize both recording characteristics and mechanical durability. The landing or contact start stop zone has an average surface roughness greater than that of the data zone. Preferably, a transition zone extends between the contact start stop zone and the data zone, the transition zone varying between the two in average surface roughness. Preferably, the contact start stop zone is textured first, followed by the data zone, thereby ensuring uniform stiction performance. Texture machines for producing such zone texturing and texturing methods are also provided.

Abstract: The invention provides discrete track magnetic recording media and methods for their fabrication. A discrete track servo pattern is imposed on an underlayer, over which a magnetic recording layer is deposited. The pattern is preferably imposed by selective laser ablation of the underlayer. Ideally the underlayer comprises sputtered carbon, which has been found to improve the signal-to-noise ratio of the subsequent magnetic layer. Optionally, a contact start/stop zone having a relatively rough surface texture is imposed, also by selective laser ablation of the underlayer.

Abstract: A magnetic recording medium and a thin film planar magnetic head form an assembly. The magnetic recording medium of the assembly includes a magnetic coating having a residual magnetization value (Mr) and a thickness value (t) which together form a high product value (Mr)(t) which is preferably greater than about 1.8 memu/cm.sup.2. This coating also has a high coercive field value of Hc which is preferably greater than about 2,200 Oe. The ratio formed by dividing the (Mr)(t)product value by this coercive field value Hc((Mr)(t)/Hc) is preferably approximately 0.7.times.10.sup.-3 memu/cm.sup.2 /Oe or 0.8.times.10.sup.-3 memu/cm.sup.2 /Oe. The product of the (mr)(t) product value and the coercive field value Hc ((Mr)(t)(Hc)) is preferably greater than approximately 4000 Oe.times.memu/cm.sup.2.

Abstract: A magnetic recording disk includes a silicon substrate which is extremely flat and essentially asperity-free. A nonmagnetic underlayer is deposited on the silicon to enhance the magnetic performance of the magnetic layer which is deposited on the underlayer. A protective nonmagnetic overlayer is deposited on the magnetic layer.

Abstract: A composite structure for magnetic recording includes a core member of polymeric material to which is bonded at least one silicon disk having a magnetic recording material on its outer surface. The silicon disk surface provides optimal flatness and smoothness characteristics for a magnetic recording substrate, while the polymeric core member provides strength to the structure.
