    • A lighting apparatus of the present invention includes light source (101), rod integrator (105), reflecting mirror (103), diffusion plate (104) disposed adjacently to reflection mirror (103), reflective polarizing plate (107), and wavelength plate (106). The lighting apparatus further includes curved mirror (102) disposed among light source (101), reflecting mirror (103), and diffusion plate (104). Reflecting mirror (103) and curved mirror (102) include apertures (102a and 103a) formed to allow at least light from light source (101) to pass. Curved mirror (102) reflects light leaked from the entrance plane side of rod integrator (105) toward aperture (103a) of reflecting mirror (103).

    • Embodiments of the invention improve the power consumption and response speed of a heater for the gap flying height (hg) adjustment, to minimize an influence that the heater has on a life of a read element, and to provide a heater having resistance lines reduced in breaking and ensuring higher reliability. In one embodiment, a read/write element is formed near an air bearing surface (ABS) on a slider, and the circumference of the read/write element is filled with alumina. The read/write element includes an upper magnetic pole piece, a lower magnetic pole piece, a coil, and a resist filling around the coil, and a read element (MR) for performing reading, and an upper shield and lower shield for protecting the read element from an external magnetic field. A heater for adjusting the flying height is provided between the slider and the read/write element but near the read/write element. A temperature gradient relaxing material having a thermal conductivity higher than that of the heater and that of a material (alumina) filling around the heater is formed near the heater.
