摘要： A magnetic head includes a coil for generating a magnetic field, and an electroconductive film superposed over the coil in the axial direction of the coil. The film is formed with a hole in the center. The electroconductive film is composed of a non-magnetic substance, and a first slit is formed in the electroconductive film extending from the hole to the outer peripheral edge of the electroconductive film. A second slit surrounds the inner peripheral edge of the electroconductive film. A continuity component is formed to electrically connect the inner peripheral edge of the electroconductive film to a radially outer region of the electroconductive film.

摘要： A head slider in a magnetic disk drive wherein provisions are made to facilitate the evaporation of lubricant adhering to the slider and thereby substantially reduce the chance of the fly height of the slider becoming unstable due to a lubricant drop. A head element, a heat generating element, and a multilayered heat conducting structure formed from multiple layers stacked along a longitudinal direction of the slider, with at least one layer extending up to portions near both lateral sides of the slider, are embedded into a nonmagnetic insulating layer formed in an air exit end portion of the slider. The heat generated by the heat generating element is efficiently conducted throughout the nonmagnetic insulating layer to heat the entire structure of the nonmagnetic insulating layer. As a result, the lubricant adhering to any portion of the nonmagnetic insulating layer is efficiently heated, causing the lubricant to evaporate or flow.
