英文摘要 | The present invention provides a semiconductor laser, an optical head, an optical disk apparatus and the manufacturing method of the semiconductor laser wherein the recording density of a recording medium can be enhanced by increasing the intensity of a laser beam output from a small aperture and the miniaturization and the enhancement of a data transfer rate are enabled. For the semiconductor laser, a low-reflective multilayer film is buried in the small aperture and further, a TiO2 film having a high refractive index is arranged on the side of the surface of an opening. The wavelength of a laser beam is reduced in the TiO2 film and near-field light easily leaks out from the aperture provided to a metallic shade. |
