Abstract: In a disk drive actuator head stack assembly, magnetic transducers including magnetoresistive (MR) read heads are connected to a current source and configured to provide an MR sensor current to each MR head wherein the direction of current flow for the MR sensor current in each MR head is the same relative to the actuator for all of the MR heads in the actuator head stack. This configuration allows all of the MR heads in the head stack assembly to initialized simultaneously by applying a homogeneous magnetic field to the head stack assembly, thus providing the capability of initializing the MR heads at the actuator or disk drive level rather than requiring that the MR heads be initialized individually.

Abstract: A head suspension assembly comprises a support arm 3 carrying a read/write head and, extending along and clamped to tile support arm, a tube 5 containing a plurality of insulated wires 4 connected to the head. A filler 7 is introduced into the space around and between the wires 4 in a part of the tube and the part of tile tube containing the filler is clamped by a claw 6 to the support arm. The filler prevents the wires breaking at the point of clamping.

Abstract: A flanged load beam (10;20) in a transducer head suspension assembly is provided with reinforcement means (7;8) which does not increase the height of the load beam. The reinforcement means can be in the form of longitudinal ribs (7) disposed between the flanges (6). The reinforcement means can also be provided by bending over the flanges (6) to form wings (8). Alternatively, the flanges can be bent over towards the centre of the load beam. Provision of such reinforcement means enables the overall height of the load beam to be reduced.

Abstract: A head suspension assembly 10 wherein a tube 5, through which pass a plurality of covered wires 4, is clamped with a securing unit 6. A space between the covered wires 4 and the tube 5 is filled with a filler 7. The part of the tube 5 that is filled with filler 7 is clamped with securing unit 6. The securing unit 6 preferably is a claw section on the head suspension assembly. It is preferable that the tube 5 is able to transmit light and the filler 7 can be cured by light.
