A disc cartridge which is capable of effectively preventing undesirable and deteriorating recording and playback characteristics of an optical disc accommodated and retained therein due to the effects of dust particles and other foreign materials being adhered to the surfaces of the optical disc. In accordance therewith, shock relieving or sealing members close a gap between the shutter and the case of the disc cartridge to prevent dust particles and other foreign materials from intruding onto the surfaces of the optical disc. In addition, sheet-like members are provided in this disc cartridge for cleaning the surfaces of the optical disc.

An optical recording medium recording and reproducing apparatus for recording information on an optical recording medium and/or reproducing information therefrom by irradiating the optical recording medium with laser light by the use of a two-group objective lens composed of at least first and second lenses. This apparatus is provided with: a light source for emitting laser light; a first lens for converging laser light emitted from the light source; a second lens interposed between the first lens and the optical recording medium; a detecting unit for detecting a kind of the recording medium; and a movement unit for changing the distance in the direction of an optical axis between the first and second lenses by causing a relative movement between the first and second lenses. Further, the distance between the first and second lenses is changed by the movement unit, which causes the second lens to move, according to a result of a detection, which is performed by the detecting unit. Thereby, the numerical aperture NA of the objective lens is increased. Moreover, the influence of aberration is mitigated. Consequently, the high-density recording and reproducing of information signals can be achieved.

There is provided an optical pick-up device capable of eliminating a spherical aberration due to a thickness error of an optical disc. The optical pick-up device includes a convex lens having a flat surface opposed to a surface of an optical recording medium, and having a predetermined refractive index, and an objective lens disposed such that the convex lens is interposed between said optical recording medium and the objective lens. A position-detecting means detects a position relation between the light-incident surface of the optical recording medium and the flat surface of the convex lens, based on first and second detection signals. A drive means drives the convex lens along an optical axis thereof such that the convex lens is caused to move in the opposite directions toward the optical recording medium or the objective lens, whereby a distance between the light-incident surface of the optical recording medium and the flat surface of the convex lens is controlled based on the first and second detection signals.

An improved method for manufacturing liquid crystal device is described. The method comprises mating a pair of substrates with an inner space therebetween, sealing the periphery of the mated substrates except for inlet ports, placing the mated substrates in a vacuum chamber, evacuating air from the inner space between the substrates by virtue of the differential pressure between the inner space and the vacuum chamber, pouring a liquid crystal material into the inlet ports, introducing the liquid crystal material into the inner space by elevating the pressure of the vacuum chamber at an elevated temperature, cooling the liquid crystal material, and closing the inlet ports by means of a sealing member. The removal of the superfluous portion of the liquid crystal material is done only after closing of the inlet ports.
