摘要： A negative pressure flying head slider includes an air bearing surface of a substantially rectangular shape disposed in opposed relation to a rotating magnetic disk. One side rail of the slider is adapted to be located at an outer periphery-side of the magnetic disk when the slider is mounted on a magnetic disk device, and has an inflow-side side rail portion which is disposed at an air inflow end-side of the slider, extending generally parallel to the longitudinal direction of the slider, and an outflow-side side rail portion which is disposed at an air outflow end-side of the slider, extending in a direction of a yaw angle. The angle of the outflow-side side rail portion with respect to the inflow-side side rail portion is greater than the maximum value of an absolute value of the yaw angle. The slider further includes a recess defined by a cross rail and the side rails, and a slit formed in the cross rail to permit the recess to communicate with the air inflow end of the slider. A magnetic transducer is provided at that portion of the slider disposed adjacent to the air outflow end of the slider.

摘要： A magnetic head slider mounted on a magnetic disk unit for supporting a magnetic head that writes and reads information to and from a magnetic disk is constructed such that a depth δs1 from the surfaces of leading and trailing pads, which come into contact with a medium surface when the disk is at rest, to stepped surfaces formed on the air inflow side of the leading pads, a depth δs2 from the contact surfaces to stepped surfaces formed on the air inflow side of the trailing pad and a step depth δs3 from the contact surfaces to the surfaces of side rails are in a relation of δs1≦δs2≦δs3. With this arrangement, the slider can follow the waved medium surface at a low flying height with a small flying height fluctuation, thus realizing high density recording, high reliability and reduced cost of the magnetic disk unit.
