Improved head gimbal assemblies reducing TMR in a hard disk drive are provided. Input voltage is rectified in a multi-level rectifier network having switched capacitors in an ascending-bank configuration for passing voltages in uniform steps between zero volts up to full received voltage VDC. The apparatus generally comprises an anti-stiction member that is interposable between the moveable element and the substrate. The clamps can also include compressive spacers and safeties for managing the compressive forces exerted on the solar panels. The Diameter server generates a message restriction instruction that includes the control information, and transmits the message restriction instruction to one or more of the Diameter clients to initiate the message restriction process based on the control information.
