Abstract:
A magnetic recording device for reading or writing magnetically, comprising:(i) a base plate;(ii) a plurality of magnetic disks, each comprising a substrate and a magnetic layer;(iii) a hub fixedly attached to the disks for supporting the disks;(iv) a motor attached to the base plate and operable to rotate the hub;(v) a plurality of magnetic read/write heads, each associated with the surface of a disk;(vi) an actuator for supporting the heads and moving the heads across the disks;(vii) a support shaft attached to the base plate; and(viii) a load/unload structure for displacing the heads from the disk comprising (a) an elongated body having a height H, (b) a base portion having a length L and fixedly attached to the base plate, and (c) a plurality of ramps extending outwardly from the body, the structure mounted through one or more holes in the body onto the support shaft so that the support shaft extends along a portion of the height of the elongated body to support the structure in an upright position substantially perpendicular to the base plate, the structure having an H/L aspect ratio of greater than about 2.
