Abstract: Embodiments of the invention reduce damage to a disk recording medium when a slider flying above the disk recording medium inside a magnetic disk drive comes into contact with the disk recording medium due to slider vibration. In one embodiment, a magnetic head slider includes a front pad, a rear pad, and carbon protective films. The front pad includes a step bearing surface disposed on the side of a leading end and leading side rail surfaces formed on the step bearing surface. The rear pad includes a rear step bearing surface disposed across a deep groove surface from the front pad and a trailing side rail surface formed on the rear step bearing surface. The carbon protective films are formed on regions including vertices of slider corner portions, respectively. The leading side rail surfaces and the trailing side rail surface are formed substantially on the same level. The carbon protective films are harder than a slider base material and have a small coefficient of friction. The films have a film thickness of about 10 nm or more.

Abstract: 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.

Abstract: A decrease in the lift-up degree of the outflow end of a slider at an altitude of 3,000 m is set to be less than 2 nm or to be zero in order to set the lift-up degree of the outflow end to be less than 10 nm. There is provided a magnetic disc apparatus in which the action point of positive pressure is shifted toward the inflow end but the action point of negative pressure is shifted toward the outflow end so as to enhance the influence upon the outflow end by the negative pressure in order to effect an action in the increasing direction of the lift-up degree of the outflow end when the pressure is reduced. Further, it is possible to increase the lift-up degree of the outflow end when the pressure is decreased. The action point of the equivalent load is offset from the action point of positive pressure toward the inflow end, and the distance between the action point of the positive pressure and the action point of the equivalent load point is set to be greater than 0.1 times as large as the overall slider length.

Abstract: An injection control method for an injection molding machine uses a step of filling a molten resin into a mold with an injection screw incorporated in a heating cylinder while changing an injection speed of the injection screw at a plurality of positions, and a dwell pressure application step of applying a pressure into the mold after filling. A predetermined filling pressure for determining a closing degree of a check valve is preset. The filling step includes comparing stroke information concerning an actual position of the injection screw with information concerning a reference position of the injection screw when one of pieces of information concerning a filling pressure, that changes in the filling step, reaches the predetermined filling pressure, and adjusting a subsequently performed change operation based on a difference between two pieces of information.
