摘要： A magnetic disk drive for carrying out reading/writing of information to/from a magnetic disk having a plurality of tracks including an innermost circumference track and an outermost circumference track. The disk drive includes a rotary actuator and a magnetic head mounted on a magnetic head slider which has separate writing and reading elements. The elements have a magnetic gap for reading and writing the information on a magnetic disk. A rotary actuator arm has one end connected to a rotary actuator and the other end connected to the magnetic head slider. The head slider has an inflow end and an outflow end for the fluid flow generated by the rotation of the disk and at least one bearing which generates a dynamic pressure by the fluid flow. The head is provided close to the outflow. A skew angle created between the magnetic gap length direction and the rotating direction of the disk is substantially constant between the innermost and the outermost tracks. The bearing is arranged at a given angle with respect to the rotating direction so that the outflow end is located on the outer circumferential side of the magnetic disk from the inflow end.

摘要： According to the present invention, there is provided a magnetic disk memory system. An embodiment of this system comprises a magnetic disk of a perpendicular recording type, including a soft magnetic backing layer and a magnetic recording layer of a perpendicular magnetic anisotropy formed on the backing layer, and a magnetic head for writing or reading of data with respect to the magnetic disk, wherein the magnetic head comprises (a) a pair of main magnetic poles each of which made of a material having a high magnetic permeability, one end of the each pole being located so as to face the magnetic disk surface, (b) a non-magnetic interlayer provided between two main magnetic poles of the pair, (c) a recording coil disposed so as to generate a magnetic flux passing through the magnetic disk via the main magnetic poles, and (d) an MR element provided via an insulation layer on the other ends of the pair of main magnetic poles, one MR element having a film surface parallel to end surfaces of the other ends of the main magnetic poles, and being magnetically coupled with the pair of main magnetic poles.
