Abstract: A FOS is provided for electrically connecting a data transfer head with a PCCA. The FOS comprises a polymeric layer supporting an electrical trace. The electrical trace comprises an uninsulated pad surface configured for electrically engaging a solder interconnect of the PCCA. The polymeric layer comprises a continuous portion covering the pad and opposing the pad surface. A method is provided comprising providing the FOS comprising the electrical trace and the polymeric covering, contactingly engaging the pad surface portion of the trace with the solder interconnect portion of the PCCA, and conducting heat through the polymeric covering to reflow the solder interconnect, thereby electrically connecting the FOS to the PCCA.

Abstract: The present invention includes a method and apparatus for attenuating flexible circuit resonance. The apparatus includes a flexible circuit assembly. The flexible circuit assembly has a flexible circuit having a flexible cable with first and second sides. The flexible circuit assembly also includes a circuit support. The circuit support includes a base having top and bottom surfaces. The bottom surface is attached to the first side of the flexible cable. The circuit support also includes a support wall extending substantially perpendicularly relative to the top surface of the base. The support wall has a first face, which is substantially oriented towards the top surface of the base. The first side of the flexible cable is attached to the first face and also faces a second face of the support wall to thereby reverse a direction in which the flexible cable faces.

Abstract: An actuator lock to hold the disk drive positioner in the parked position after shut down includes a latch arm extending from a selected portion of the positioner, a solenoid, a locking lever and a latch. The solenoid has a coil and an armature. The armature is moveable between a normally biased first armature position and a second armature position. The solenoid coil when energized by a current pulse upon shut down of the disk drive moves the armature into the second position. The locking lever is rotatably mounted to the armature and has a first end. The locking lever is movable between a normally biased first lever position and second lever position. The first end engages the latch arm when the positioner has been brought to the parked position by the current pulse and the armature coil has also been energized. When the armature is in the first armature position, the locking lever is non-interactive with the latch arm.
