Optical Disk Loading

      This invention provides concepts for loading a data storage
media disk to a drive spindle involving three moving steps, first
with a vertical move, and follow with a lateral and another vertical.

      CONCEPT 1: If the optical head 6 can be moved to partially
clear the outer portion of its path, the loading process is
illustrated by Fig. 1 wherein:

      A. Disk 3 and its caddy 4 are inserted into the drive until its
center is colinear to that of the upper spindle 1 and the lower
spindle 5.

      B. With the optical head 6 at its inner most position I, the
disk 3 is lowered onto the lower spindle 5 and then is clamped
between the upper spindle 1 and the lower spindle 5, the bias coil 2
is moved into place while the caddy 4 is lowered further to allow a
clearance between it and the disk 3.

      C. To clear way for the optical head when it moves to its outer
most position O, the caddy 4 is shifted laterally in the X direction
until the cut-out 8 covers the entire working zone of the optical
head 6.

      CONCEPT 2: If the optical head assembly 6 permanently occupies
the entire optical head working zone, then the lower spindle 5 must
have the ability to move in the vertical direction along its center
axis.  The loading process in this case is illustrated by Fig. 2
wherein:

      A&B.  With the lower spindle 5 at its upper most position U,
the disk 3 and its caddy 4 are inserted into the drive until its
center is...
