摘要:
A flying type head slider is provided having a rear surface faced to a magnetic disk for recording and/or reproducing signal on or from a magnetic disk. The flying type head slider includes a center rail formed on the rear surface extending from a front end to a back end of the slider, a magnetic head mounted at the back end of the center rail and a pair of two rails also formed on the rear surface respectively located at both sides of the center rail. The two rails respectively have an inner side wall facing to a side wall of the center rail and an outer side wall. The both side walls are tapered and not parallel relatively to the side wall of the center rail so that the magnetic head can be floated by flying force cause by air flow between the rails and a surface of rotating magnetic disk.

Disclosed is a hovering-type head slider in which the variation in static hovering distance is reduced as much as possible, thereby making it possible to obtain a hovering distance which is constant with respect to variation in the skew angle and in the linear velocity.The hovering-type head slider includes two rails 16 and 17 which are formed on either side portions of the surface thereof opposed to a recording medium and which serve as air bearing surfaces, a tapered portion provided on the air flow inlet side of each rail, and a magnetic head 15a provided on an end surface on the air flow out let side, wherein the rails 16 and 17 branched into branch rail portions which extend obliquely toward the air flow outlet end from a position near the center with respect to the direction of the air flow.
摘要:
A floating-type head slider having a rail plane that functions as an air bearing in accordance with a kinetic pressure of an air flow caused by rotation of a recording medium, that supports a recording/reproducing device for recording and reproducing information, and that keeps a predetermined gap between the device and a surface of the recording medium, wherein an edge of the rail plane includes only segments of ellipses and circles, and tangent lines of the segments, preferably the edge of the rail plane is continuous to provide a floating head slider having high reliability even in a dusty environment and a recording/reproducing apparatus in which such a floating head slider is employed.

Described herein is a hard disk drive HDD which adopts a CSS type floating or levitation head device. A condensation sensor is provided on the inner surface of a housing or chassis. Since the capacity of the chassis is large and moisture adsorbed by the chassis due to dew condensation or the like is hard to dry, the condensation or the like produced on the inner surface side of the chassis can be detected accurately by placing the condensation sensor on the inner surface of the chassis. The condensation sensor may be attached to an arm or suspension constituting an actuator, a head slider, a flexible printed board, or a portion or the like formed of the same material as that for a magnetic disc. When the condensation or the like is detected by the condensation sensor, the magnetic disc is allowed to stand by in a state of remaining stopped rotating until it is not detected. Thus, damage to the magnetic disc and breakage of the head slider or the like due to their sticking can be previously prevented from occurring. Owing to the above construction, high humidity or condensation can be effectively detected and damage to a recording medium and breakage of the head slider or the like can be prevented satisfactorily.

摘要:
A floating type head slider used in a disc drive using a disc-shaped recording medium, and adapted to float from the disc-shaped recording medium when the disc-shaped recording medium is rotationally operated. This head slider comprises an air lubricating surface formed on the surface opposite to the disc-shaped recording medium, a taper portion provided at the air inflow end side of the air lubricating surface, a recessed portion of a fixed depth adapted to produce negative pressure, the recessed portion being provided on the center line along the direction from the air inflow end side toward the air outflow end side of the air lubricating surface and being such that the air inflow end side is closed and the air outflow end side is opened, and a groove portion formed along the center line extending from the recessed portion toward the end portion of the air inflow end side of the air lubricating surface, and formed so as to have a width narrower than the recessed portion which divides the air lubricating surface and to have the same depth as that of the recessed portion.This head slider is floated with a fixed floating quantity from the surface of the disc-shaped recording medium in a stable state by positive pressure produced between the air lubricating surface and the surface of the rotationally operated disc-shaped recording medium and negative pressure produced by the recessed portion.
