Abstract
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.
