Abstract
The head slider in accordance with the present invention comprises a thin-film magnetic head including a magnetoresistive device and an electromagnetic transducer, and a heater adapted to generate heat upon energization. At least one of a reproducing bump, a recording bump, and a heater bump includes a bypass layer extending in a direction intersecting a bump extending direction, a first bump portion positioned closer to a pad-forming surface than is the bypass layer, and a second bump portion positioned on the side of the bypass layer opposite from the first bump portion. The first and second bump portions are displaced from each other in the bypass layer extending direction.
