Title: Optical head, recording and reproducing device, and element for varying optical coupling efficiency
Inventor: NISHI NORIAKI
IPC: G11B7/135
Filed: 2001-11-19
Abstract: PROBLEM TO BE SOLVED: To provide satisfactory recording and reproducing characteristics by using the light source of high productivity or light source of comparatively small light output rating by sufficiently reducing laser noise in the case of reproduction even when the output power ratio of the light source in recording and reproducing is reduced. SOLUTION: In an optical head 104, the intensity of light emitted from a light source 2 is appropriately and variably controlled when passing an element 3 for varying optical coupling efficiency and especially in a reproducing mode, the light is made incident on an optical disk 102 with light intensity smaller relatively to the light intensity of the light source 2. Therefore, by controlling optical coupling efficiency in the element 3 for varying optical coupling efficiency while switching it in recording and reproducing, even without extremely enlarging the output power ratio of recording and reproducing on the side of the light source 3, the level of light with which an optical recording medium is irradiated can be remarkably changed between recording and reproducing.

Abstract: <P>PROBLEM TO BE SOLVED: To provide a liquid crystal display device which is capable of solving the degradation of a picture which is to be generated in renewing a picture and also whose response speed is of satisfactory.  <P>SOLUTION: This display device is a liquid crystal display device performing display by holding chiral nematic liquid crystal between the substrate 11 provided with electrodes 12a, 12b and the substrate 21 provided with an electrode 22 and by utilizing selected reflection of the liquid crystal. The anisotropy of dielectric constant Δε of the liquid crystal is Δε<0 and also |Δε|>10. When a transverse electric field D1 being roughly parallel with surfaces of the substrates is generated between the electrodes 12a, 12b, the liquid crystal becomes to be in a focal conical state in which its helical axis is parallel with the transverse electric field D1. On the other hand, when a vertical electric field D2 being roughly vertical to the substrates is generated among the electrodes 12a, 12b and the electrode 22, the liquid crystal becomes to be in a planar state in which its helical axis is parallel with the vertical electric field D2. Even when the electric fields D1, D2 are relatively high voltages, the phase of the liquid crystal is changed without loosening its twist and as a result, the response time is short.  <P>COPYRIGHT: (C)2003,JPO
