Abstract: According to the method of producing organic pigment fine particles of the present invention, when producing organic pigment fine particles by allowing two or more solutions at least one of which is an organic pigment solution in which an organic pigment is dissolved to flow through a microchannel, the organic pigment solution flows through the microchannel in a non-laminar state. Accordingly, the contact area of solutions per unit time can be increased and the length of diffusion mixing can be shortened, and thus instantaneous mixing of solutions becomes possible. As a result, nanometer-scale monodisperse organic pigment fine particles can be produced in a stable manner.

Abstract: A magnetic head slider has a recess portion recessed with respect to the center rail. The recess portion has a spherical or oval-spherical projection, which includes a read element and a write element disposed in the recess portion. The recess portion may prevent increasing flying height of a slider base due to projection height h may be suppressed, and may secures higher air film stiffness, so that consequently flying stability of the slider may be improved.

Abstract: Embodiments of the present invention provide a slider that may suppress contamination from being attached to the flying surface of the slider without influence on reduction of the flying height of the slider, and a method for producing the same. According to one embodiment, ions exerting an effect of decreasing surface energy are implanted in the whole surface of a flying surface of a magnetic head slider except for a front rail surface and a center rail surface. According to this, contamination is prevented from being attached to a front step bearing surface, a side step bearing surface, a center step bearing surface and a negative pressure groove where contamination is particularly liable to be attached in the flying surface of the magnetic head slider, so as to suppress destabilization in flying of the slider.

Abstract: Embodiments in accordance with the present invention provide a magnetic head slider capable of securing a larger flying margin even when position variations occur at the time of flying. Embodiments of the present invention also provide a magnetic head slider having an excellent flying following capability. A read element and a write element of a magnetic head slider are arranged on a spherical or ellipsoidal projection and this projection is formed on a thin film magnetic head part. This may prevent a flying margin from being reduced by variations in flying position and may prevent a manufacturing step from being caused on the spherical or ellipsoidal projection. Moreover, by making the constituent ratio of the thin film magnetic head part on an air-bearing surface of the magnetic head slider 100 to be 7% or more, the read element and the write element are arranged at a pressure center position on the center rail surface of the air-bearing surface.

In one embodiment, a magnetic disk apparatus comprises a magnetic disk including tracks for recording data; a magnetic head slider disposed with a magnetic head that flies over the rotating magnetic disk and records data to, or plays back data from, the magnetic disk; and a control device that controls the operation of the apparatus. Slider flying height data that vary inside the tracks are prerecorded in the tracks of the magnetic disk. The control device controls the operation of the magnetic head slider with respect to the magnetic disk on the basis of the slider flying height data recorded in the tracks.
