Clamp and Spacerless Spindle Motor for File Applications

      Disclosed is a method for clamping and holding disks on a
spindle.

      In Fig. 1, the illustrated invention utilizes two elastomer
rings 1 which are affixed to the motor hub 2 and are a set for each
disk used.  The embodiment shown involves two elastomer rings;
however, this can be one molded single or double lobed ring or a
molded sleeve encompassing many molded lobe's for multiple disks.
The disk is slipped over the lobe of the elastomer rings 1 and held
in place centrally and axially by the even and concentric pressure of
the two rings 1.  This can be duplicated for any number of disks.

      In Fig. 2, this embodiment shows the use of one elastomer ring
1 and the use of a spacing hub on the motor body 2.  As in Fig. 1,
the disk is slipped over the elastomer and is held radially with
minimal vector forces against the mounting hub.  This is ideal for
one or two disk files.
