A magnetic head, according to one embodiment, includes a rowbar substrate having a tape support surface and a gap surface at a substrate edge. A closure is positioned opposite the gap surface of the rowbar substrate, the closure forming a portion of the tape support surface. A recessed gap region is interposed between the gap surface of the rowbar substrate and the closure, the recessed gap region having a recessed gap profile that extends between the gap surface of the rowbar substrate and the closure, the recessed gap region having a transducer row with at least one magnetic sensor on the gap surface of the rowbar substrate. An insulation layer is positioned over the recessed gap profile of the recessed gap region.

A hard disk drive includes a cover coupled to a base deck to create an enclosure. The hard disk drive further includes data-recording components and non-data-recording components positioned within the enclosure. At least one of the non-data-recording components includes a surface with a surface treatment that promotes condensation of water vapor.

Approaches to patching a leaky hermetically-sealed device include the use of a laminate rework patch that includes an adhesive tape layer, an aluminum sheet layer, and an outer cover layer, and whereby a viscous adhesive is injected or otherwise applied between the patch and the device leak location, over a layer of primer material, to fill the leak and stop the leakage of gas from inside the device. The thickness of the viscous adhesive, and thus the curing time and temperature of the viscous adhesive, can be managed by way of the thickness of the adhesive tape layer.
