Abstract: An apparatus and associated method is presently disclosed for a control circuitry capable of managing a heat source used in data storage applications. Various embodiments of the present invention are generally directed to a heat source directed at a data storage medium with a synchronization signal and a serial interface that are each selectively activated via a demultiplexed write gate signal. The selective activation allows for pulsed operation of the heat source resulting in reduced duty cycle and temperature during a write operation.

Abstract: An actuator arm for a disc drive data storage device has an upper outer surface in a first plane, a lower outer surface in a second plane substantially parallel to the first plane, a peripheral outer surface substantially perpendicular to the first and second planes, and a voice coil embedded within the outer surfaces of the actuator arm. The actuator arm is used in a disc drive containing one or more data storage discs and preferably has a pre-amplifier embedded within the outer surfaces of the actuator arm as well as conductors preferably between the read/write head and the pre-amplifier within the outer surfaces of the actuator arm.

Abstract: A method and system are disclosed for protecting an electrical component from electrostatic discharge prior to its electrical connection to an additional component. Specifically, a flex on suspension circuit of a disc drive that is electrically connected to the read/write head is disclosed as having exposed leads for connection to a printed circuit cable assembly. The exposed leads are shunted with a solder conductor such as solder tape after testing of the circuit and head to prevent electrostatic build-up across the read and write elements. The flex on suspension circuit is then electrically connected to the printed circuit assembly cable by reflowing the solder conductor to bond the exposed leads of the flex on suspension circuit to the electrical contacts of the printed circuit assembly cable and also to remove the electrical short established between the exposed leads by the solder conductor.
