    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： A magnetic disk drive that records and reproduces data onto and from a magnetic disk is provided with a rotary actuator arm tilt which has a length such that the variation of the skew angle formed where a line, connecting the center of rotation of rotary actuator, and one end of the rotary actuator crosses the track moving direction of the magnetic disk is a minimum. A composite head unit is provided and composed of a write head and a read head integrated into a single unit which is mounted on the rotary actuator arm, wherein in order to minimize the largest absolute value of the skew angle formed where the disk radius direction crosses the track width direction of the composite magnetic head on a given write track in the range from the innermost write track position to the outermost write track position. The composite magnetic head unit is constructed to meet at least either the condition that the unit is mounted obliquely with respect to a line connecting the center of rotation of the actuator and the composite magnetic head unit or the condition that the write head and the read head are stacked with the write head being shifted from the read head in the track width direction toward the outer circumference or the inner circumference to compensate for a track deviation due to the skew angle.
