Hermetic sealing with high-speed transmission for hard disk drive

A hermetic electrical connector, comprising:

• means for externally connecting to a device;
• means for internally connecting to the device;
• and
• means for providing a barrier/connection between the means for externally connecting to the device and the means for internally connecting to the device, the barrier/connection providing means comprising a dielectric material multilayer structure and one or more gas choke layers embedded in the dielectric material multilayer structure.

A hard disk drive, comprising:

• one or more magnetic media;
• one or more sliders;
• one or more magnetic head assemblies;
• and
• a hermetic electrical connector, comprising:
• an external connector;
• an internal connector;
• and
• a barrier structure disposed between the external connector and the internal connector, wherein the barrier structure comprises:
• one or more layers embedded in dielectric material, wherein the one or more layers each includes a plurality of opening;
• a first plurality of connecting pads disposed on a first surface of the barrier structure;
• and
• a second plurality of connecting pads disposed on a second surface of the barrier structure, wherein the first plurality of connecting pads are offset from the second plurality of connect pads.
