A magnetic head disposed in a slider arranged with an interval with respect to a magnetic disk includes a sensor that is positioned in a stepped-back position from an air bearing surface facing the magnetic disk, an insulating film that is positioned on the air bearing surface and that covers the sensor; a pair of lead films, the lead films being electrically connected to the sensor such that at least portions of the lead films are exposed on the air bearing surface, and being configured to transfer a temperature change of the air bearing surface to the sensor.

A magnetic head disposed in a slider, that is arranged at an interval from a magnetic disk includes a sensor disposed in a position that is opposed to the magnetic disk, a heat conductive film that is positioned on an air bearing surface opposed to the magnetic disk, and that is formed so as to overlap the sensor, of which a height in a direction perpendicular to the air bearing surface is more than a height of the sensor, and that transfers a temperature change of the air bearing surface to the sensor, and a pair of lead films electrically connected to the sensor and not electrically connected to the heat conductive film.

A light-waveform measuring device and method include a complex-refractive-index measuring device and a computer-program recording medium An electric field of an electromagnetic wave, in a light region having wavelengths smaller than those of electromagnetic waves in a near-infrared region, is measured, and time-varying waveforms are outputted. Gate-pulse-light generating means, measurement-light generating means and light-detecting means for detecting measurement light, are included, The measurement light is coherent light having a wavelength smaller than those of a near-infrared region. The gate pulse light is coherent light with a pulse width smaller than a period of the measurement light. A physical quantity, based on carriers generated from the measurement light and the gate pulse light is measured.
