摘要： The present invention relates to a method for producing a transducer slider. The method involves first coating a substrate with a radiation-sensitive layer and exposing the radiation-sensitive layer to radiation according to an intensity pattern. Preferably, the intensity pattern is provided using a grayscale mask. Once the image is developed into the radiation-sensitive layer, the image is transferred into the substrate to form a transducer slider having a surface profile comprising a tapered edge. In the alternative or in addition, the surface profile may comprise a rounded corner. The invention also relates to a structure for forming a transducer slider.

摘要： Embodiments of the present invention provide a magnetic disk drive capable of allowing higher data transfer rates and higher recording densities. According to one embodiment, an upper magnetic core and lower magnetic core comprise a multi-layered magnetic film formed by alternately stacking a face-centered cubic (fcc) crystalline magnetic thin layer and a body-centered cubic (bcc) crystalline magnetic thin layer by plating. The plating bath is such that the temperature is about 30±1° C., pH is about 2.0−1.0 to 2.0+0.5, metal ion concentrations are about 5 to 25 (g/l) for Ni2+ and 5 to 15 (g/l) for Fe2+, saccharin sodium concentration is about 1.5±1.0 (g/l), sodium chloride concentration is about 25±5 (g/l), and boric acid concentration is about 25±5 (g/l). Since each layer's crystal structure is different from that of its adjacent lower layer, epitaxial growth is broken within each layer. Thus, since crystal grains are reduced in size, it is possible to lessen the decrease of the permeability μ at higher frequencies.

摘要： Embodiments of the present invention provide a magnetic disk drive with an enclosure that prevents the low-density gas from leaking out owing to reduction of shrinkage cavities near tapped holes. According to one embodiment of the present invention, an aluminum alloy is forced into the region of the base in which the tapped hole is to be made, by squeezing in the final stage of die casting to form the base. This procedure increases the density of aluminum alloy above 2.7 g/cm3, and the densified aluminum alloy in the region for tapped holes, is free of shrinkage cavities that can cause gas leakage.
