Protection from VCM Coil Wire Break

   Disclosed is the structure that is prevented from VCM
(voice coil motor) coil wire breakage.  VCM coil and Coil-Support
are parts of Hard Disk Drive (HDD).  (Fig.1)

   To protect against short-circuit and wire breakage by
handling etc., the lead wire is covered by insulation tube.
Generally coil is bonded to Coil-Support by adhesion, the tube is
also.  Curing adhesion, the glue get in the tube by capillary
attraction.  Then it is very easy to break wire, after the glue
hardened.

   Therefore, coil wire breakage can be protected by bonding
insulation tube in the middle not to enter in.  It can be achieved
that lead wire of inner side is rounded in the coil.  (Fig.2)
