摘要： A flying head slider that keeps out dust particles while improving the CFH characteristics, skew dependence characteristics, and linear speed dependence characteristics for achieving a stable fly height. A flying head slider includes a positive pressure generating surface, which includes a leading pad for ensuring pitch stiffness; a pair of side pads, which are positioned behind of the leading pad and to the right and the left for ensuring roll stiffness; and a center pad, which is positioned between the side pads and controls the fly height characteristics. Furthermore, the flying head slider includes steps, which are at a lower height than the positive pressure generating surfaces and extend from the front of the slider toward side edges thereof in order to prevent dust particles from entering an area between the flying head slider and a disk surface.

摘要： A head actuator is made thinner without sacrificing its strength to thereby achieve the thinning of a hard disk apparatus. On the base end of each of two suspensions is provided a boss that protrudes in the direction of the side on which a magnetic head is provided, and a suspension fixing section having a hole into which the bosses are inserted is formed towards the tip of an arm. The boss of one of the suspensions is inserted into the hole from the upper end section thereof, and the boss of the other suspension is inserted into the hole from the lower end section thereof. Thus, the arm is fixed in place by being held by the two suspensions from above and below.

摘要： The object of the present invention is to improve sealing performance of a seal under a specific environment. The seal is arranged in an annular space A in which a rotary shaft 1 and a housing 2 face each other, and partitions the annular space in axial direction into a vacuum space B and an atmospheric pressure space C. The seal is constituted such that a main lip 6 of the seal has an axial contact width W0 with which the main lip slides on and contacts with the rotary shaft 1 and which is set to be equal to or larger than an axial contact width W1 necessary to secure minimum sealing performance with respect to a sealed portion and equal to or smaller than an axial contact width W2 with which sliding resistance against the rotary shaft becomes a permissible upper limit, to thereby prevent the axial contact width W0 from influencing rotation characteristics with respect to the rotary member and to allow securing required sealing performance.
