    • An information recording and/or reproducing apparatus includes a laser light source from which a laser beam having a wavelength of from 220 nm to 280 nm exits; and a converging lens unit disposed at a nearfield area of a recording medium and upon which the laser beam from the laser light source is incident. The converging lens unit includes an objective lens and a solid immersion lens. The solid immersion lens is disposed between the objective lens and the recording medium, and is formed of a highly refractive material having a high transmittance. The information recording and/or reproducing apparatus records an information signal onto or reproduces an information signal from the recording medium by irradiating the recording medium with the laser beam from the laser light source.
    • 信息记录和/或再现装置包括激光源,激光束从波长220nm至280nm离开; 以及会聚透镜单元,设置在记录介质的近场区域,并且来自激光光源的激光束入射。 会聚透镜单元包括物镜和固体浸没透镜。 固体浸没透镜设置在物镜和记录介质之间,并且由具有高透射率的高折射材料形成。 信息记录和/或再现装置通过用来自激光光源的激光束照射记录介质,将信息信号记录到记录介质上或从记录介质再现信息信号。
