Embodiment Construction
[0014] In order to further understand the present invention, the structure of the magnetic recording disc drive in the prior art will be described in detail below with reference to FIGS. 1-3 .
[0015] The disk drive includes a housing 10 generally formed with a base 12 and surrounding walls 14 . An actuator, typically a voice coil motor (VCM) actuator, is supported by the base 12 . The VCM includes a rotating part rotatable about an axis 20 and a fixed part including a magnet stack 26 mounted on the base 12; Each actuator arm includes a cantilever and head assembly, such as cantilever 28 and head assembly 30 connected to arm 22 .
[0016] The disk drive includes a set of hard magnetic recording disks mounted in a stack on a rotatable hub connected to a spindle motor. The stack assembly comprising the disc pack, hub, and spindle motor is mounted in a region 32 on the housing base 12 so that the disc pack can rotate about a common axis 34, but is not depicted in FIG. 1 , The...
