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 distal-side engage portion that is fixed directly or indirectly to the flexure substrate so as to be engaged with a distal end of the magnetic head slider being mounted directly or indirectly on the head mount region, paired arm portions that are capable of being elastically deformed and are connected directly or indirectly to the distal-side engage portion so as to sandwich the magnetic head suspension, which has been mounted directly or indirectly on the head mount region, from both sides in the suspension width direction, a proximal-side engage portion that is movable in the suspension longitudinal direction in a state capable of engaged with a proximal end of the magnetic head slider being mounted directly or indirectly on the head mount region, and a spring portion that presses the proximal-side engage portion toward the distal-side engage portion, wherein the proximal-side engage portion includes a center region and paired side regions that extend from the center region toward both sides in the suspension width direction, the center region being capable of engaging with the proximal end of the magnetic head slider that has been mounted directly or indirectly on the head mount region, the paired side regions being capable of engaging with the paired arm portions, wherein the spring portion takes an initial posture of causing the center region of the proximal-side engage portion to be positioned closer to a distal side in the suspension longitudinal direction than the proximal end of the magnetic head slider, which has been mounted directly or indirectly on the head mount region in a state of being engaged with the distal-side engage portion, in a case of an operational force cancelled state in which no external operational force is applied to the spring portion, an elastically deformed posture of causing the center region to be positioned closer to a proximal side in the suspension longitudinal direction than the proximal end of the magnetic head suspension in a case of an operational force applied state in which an external operational force is applied to the spring portion, and a sandwiching posture of causing the center region to sandwich the magnetic head slider in cooperation with the distal-side engage portion in a case where the external operational force is released after the magnetic head slider has been mounted directly or indirectly on the head mount region while the spring portion being at the elastically deformed posture, and wherein the paired arm portions take a close posture in which a distance between inner surfaces thereof is narrower than a width of the magnetic head slider when the spring portion takes the initial posture, the paired arm portions are engaged with the paired side regions of the proximal-side engage portion that are moved in accordance with a posture change of the spring portion so as to take a distant posture in which the distance between inner surfaces of the paired arm portions is wider than the width of the magnetic head slider when the spring portion is shifted from the initial posture to the elastically deformed posture, and the paired arm portions are disengaged from the paired side regions so as to take a sandwiching posture that sandwiches the magnetic head slider from both sides in the suspension width direction when the spring portion is shifted from the elastically deformed posture to the sandwiching posture.
