    摘要: A microscope system includes, at least, an objective lens for converting a luminous flux from an object into a parallel luminous flux, an afocal variable magnification optical system for changing a diameter of the parallel luminous flux emergent from the objective lens into a different diameter, and an image forming optical system for forming an image out of the parallel luminous flux emergent from the afocal variable magnification optical system, and the following conditions are satisfied: 2·NA(ob)·FL(ob)≧30 (mm) 6≦Lexz/X≦10 where, NA(ob) is the maximum effective numerical aperture of the objective lens, FL(ob) is a focal length of the objective lens, X=2·NA(ob)·FL(ob), and Lexz is a distance from an object surface to the most distant end of the afocal variable magnification optical system.

    摘要: A disc-shaped optical data recording medium has a signal recording layer for reading and/or writing data using light, and a 10 μm to 200 μm thick transparent protective layer disposed over the signal recording layer. The optical data recording medium includes a protrusion projecting from a surface of the transparent protective layer on a light-incidence surface side to which light is emitted to the signal recording layer. The protrusion is disposed in an area between a center hole and a clamping area where the optical data recording medium is held when reading and/or writing data in the signal recording layer.
