Paper Abstract

The immersion system of information recording on optical cylinders is considered. The investigation results of system aberrations caused by the presence of cylindrical surfaces, immersion liquid by the change of such parameters as thickness, refractive index are presented. The recommendations on correction of such main system aberrations as spherical and astigmatism are proposed. The possibility of creation of high-aperture aspherical immersion objectives for information recording is shown. On experimental specimens of immersion-type information recording devices on optical cylinders is obtained the density of 8x11 It/mm.
