Abstract:
1. A thin film magnetic recording head having a multilayer structure in which plural thin films are laminated and being a perpendicular recording type that applies a magnetic field perpendicularly to a magnetic recording medium and performs recording, comprising: a main magnetic pole exposed on an air bearing surface facing the magnetic recording medium and guiding a magnetic flux toward the magnetic recording medium; a thin film positioned beneath the main magnetic pole from a perspective of a lamination direction and configuring a sensor or a heater configured to determine a distance from the magnetic recording medium of the thin film magnetic recording head; and a light-absorbing portion positioned between the main magnetic pole and the thin film, wherein the light-absorbing portion has a multilayer structure including at least a first light-absorbing layer, a second light-absorbing layer, and a transparent layer positioned between the first light-absorbing layer and the second light-absorbing layer.
