Optical head and optical recording apparatus

摘要

An optical head having: a graded index lens which receives incident light radiated from a linear optical guide at one end surface of the graded index lens and transmits the incident light from the other end surface of the graded index lens, the graded index lens is adapted to form a light spot at a position that is away from the other end surface from which the incident light is transmitted; a light path deflection section which deflects light transmitted from the graded index lens, the light path deflection section is arranged between the other end surface from which the incident light is transmitted and the position where the light spot is formed; and a slider which floats on a recording medium while moving relative to the recording medium, wherein at least the graded index lens and the light path deflection section are installed on the slider.
