Abstract:
1. A magnetic head slider locking apparatus for detachably mounting a magnetic head slider to a magnetic head suspension including a supporting part that is swung about a swing center directly or indirectly by an actuator, a load bending part that generates a load for pressing a magnetic head slider toward a disk surface, a load beam part that is supported by the supporting part through the load bending part and transmits the load to the magnetic head slider, and a flexure part that is supported by the load beam part, the flexure part having a flexure substrate that integrally includes a load beam part overlap region fixed to the load beam part in a state of being overlapped therewith, paired arm regions extending toward a distal end side from both ends in a suspension width direction of the load beam part overlap region, a connection region extending in the suspension width direction so as to connect distal ends of the paired arm regions, and a head mount region which extends from the connection region toward a proximal end side in the suspension longitudinal direction so as to be positioned between the paired arm regions and to which the magnetic head slider is mounted, the magnetic head slider locking apparatus comprising, a fixed portion that is fixed to the connection region and is provided with a distal-side engage portion to be engaged with a distal end of the magnetic head slider being mounted on the head mount region, an endless spring portion that is disposed to surround the fixed portion in a plan view as viewed along a direction perpendicular to the disk surface, a connection portion that connects the fixed portion to the spring portion, and a proximal-side engage portion that is provided to the spring portion so as to be engaged with a proximal end of the magnetic head slider being mounted on the head mount region, wherein the spring portion is capable of taking an initial posture where no external operational force is applied thereto so that the proximal-side engage portion is located closer to a distal end side in the suspension longitudinal direction than the proximal end of the magnetic head slider that is mounted on the head mount region in a state of being engaged with the distal-side engage portion, and also taking an elastically deformed posture where an external operational force is applied thereto so that the proximal-side engage portion is located closer to a proximal end side in the suspension longitudinal direction than the proximal end of the magnetic head slider.
