Low Profile Mechanism for Head Load/Unload

      Disclosed is a structure for Dynamic Load/Unload Mechanism to
reduce height for Hard Disk Drives (HDD).

      Usually Dynamic Load/Unload Mechanism is the structure in Fig.
1 where the head is retracted by the block installed on the base
plate of the HDD.  The contact point for the head retraction is above
the disk surface.

      Usually head height(T1) is thickness(H1) and the space between
the disk and block(G1) in Fig. 1.  The gap(G1) is the space necessary
for head loading to prevent the block to interfere with the disk.

      This discloses an idea where the contact point of the head and
block outside of the disk.  Therefore reducing the height of the
load/unload mechanism shown in Fig. 2.

      Because there is no need for a gap between the disk and the
block, height of the Dynamic Load/Unload Mechanism is reduced to only
the block thickness (H3) and head(H4) in Fig. 2.

      This invention is effective to reduce the height of the dynamic
load/unload mechanism and also can reduce the total height of the
disk enclosure.
