ABSTRACT:
An assembly is provided which has integrated suspension and actuator arm regions. At least one actuator coil layer is located in the actuator arm region. The actuator coil layer is mounted to at least one homogeneous support layer which extends between terminal ends of the assembly for supporting all layers. A hole is provided through all layers in the actuator region at a pivot point for receiving an actuator spindle. In some embodiments of the invention, a transducer coil layer may be integrated in the suspension region and may be located in substantially a common plane with the actuator coil layer. The actuator region may be provided with a silicon base which contains integrated processing circuits which are connected to the transducer coil layer. A device may be carried by the assembly for bending the suspension region with respect to the actuator arm region. A method is provided for fabricating multiple integrated assemblies substantially entirely at the wafer level, each integrated assembly having a longitudinal recording magnetic head which has a close tolerance gap.
