Title: Device for recording and reproducing recording medium and method therefor
Inventor: ISHIBASHI JUNICHI
IPC: G11B7/135
Filed: 1996-01-12
Abstract: PROBLEM TO BE SOLVED: To perform good image formation on an information recording layer of each individual recording medium having different substrate thickness and to cope with a different numerical aperture by optically moving a light source to a different position in the direction of its optical axis. SOLUTION: The thickness of substrate of an inserted disk 2 is judged by a control circuit to issue an instruction for moving the position of a laser diode 14 and the position of a photodetector 15 to positions to which the substrate corresponds, to an optical pickup 33 via a pickup control circuit. Consequently, the laser diode 14 and the photodetector 15 are moved in their optical-axial directions into their positions corresponding to the disk by a motor 17 and a motor 18 of the optical pickup 33 respectively. As a result, a spherical aberration due to different substrate thickness is minimized, and then information recorded on its information recording layer is reproduced.

IPC: H01J31/12
Filed: 1993-01-12
Abstract: PURPOSE:To restrict generation of luminescent line at the time of displaying a window signal by providing a grounded low resistance conductive film, on the outer surface of a screen panel. CONSTITUTION:A low resistance conductive layer 11 such as copper foil, for example, of the resistivity of 10<-7>OMEGA, is provided on the outer surface of a screen panel 2, and is grounded, to form a reflection type flat cathode-ray tube 9. A capacitor of low impedance is formed by an ITO conductive layer 3 of the inner surface of the panel 2 and by a copper foil 11 of the outer surface, in the tube 9. When a window signal is input therein, a phosphor surface 4 on which an electron beam scans, and the panel 2 are to be charged negative, however, since the panel 2 is ac-connected with a GND, fluctuation in the load is absorbed by the GND at low resistance. Variation in the electric field in a CRT is thus almost eliminated, and a luminescent line can be minimized. When a window signal, for which fluctuation in current is large, the luminescent line can be restricted.
