摘要： A head support mechanism includes a head to write/read information, and a head support member to support the head. The head support member has parts delimiting an opening at a portion thereof in which opposing parts which delimit the opening in a width direction of the head support member are elastically deformable. Protrusions are formed on edges of the opening, and piezoelectric elements are mounted on the protrusions to enable deforming of the head support member in a direction of positioning of the head.

摘要： If a large external impact is applied to a magnetic disc apparatus, a slider jumps from a disc surface and rotates. When the slider jumps and rotates, its edges re-contact the disc surface to damage this surface. To reduce the rotation angle of the slider to control its position if an impact is effected, the present invention provides a roof on a load arm to reduce the contact angle at which the slider contacts the disc surface in order to relax the impact upon a contact.

摘要： A magnetic head slider assembly for a magnetic disk type recording/reproducing apparatus includes a slider body, a sliding pad provided on the slider body and projecting beyond a disk facing surface thereof, a thin film layer disposed at one end of the slider body, a magnetic head constituted by the thin film layer as an integral part thereof, and a core pad projection incorporating therein a core of the magnetic head and projecting beyond an adjacent disk facing surface of the slider body. The sliding pad is provided at a region of the slider body ahead of the core pad projection and prevents generation of a floating force by making use of a relative movement between the slider body and the magnetic disk. The core pad projection is not formed as a continuation of the slider body and is separated from the sliding pad a predetermined distance longitudinally of the slider body by a recess interposed therebetween whereby the core pad projection is positioned closer to the magnetic disk than a back end of the sliding pad.
