Title: Optical disk device
Inventor: OSADA ATSUSHI
IPC: G11B19/20
Filed: 2000-03-08
Abstract: PROBLEM TO BE SOLVED: To provide an optical disk device in which rechucking is automatically conducted so that the amount of eccentricity becomes not larger than a prescribed threshold value by using a simple constitution. SOLUTION: An amount of eccentricity x of a disk 20 mounted on a turntable 7 is computed by a system controller 10. When the amount x approaches a threshold value A, a focus servo is turned OFF, either one of a first mode, in which a spindle motor 6 is stopped and chucking is released, or a second mode, in which the motor 6 is set to run at a low speed and a soft chucking state is set, is set. Then, rechucking is automatically repeated from the first or the second mode until the amount x becomes not larger than the value A. Thus, especially during a writing in a high speed rotation/chucking of a reproducing operation, no frequent retry of error processing is conducted by the generation of an error due to improper follow-up of a tracking servo caused by the eccentricity by employing a simple constitution.  Moreover, reduction in the efficiency of reproducing/writing is prevented and highly precise recording/reproducing operations are made possible.

Filed: 2000-03-16
Abstract: PROBLEM TO BE SOLVED: To simplify the process and to increase the viewing angle of a liquid crystal display device by allowing liquid crystal directors on the plane parallel to two substrates to be present in all directions in any region on this plane. SOLUTION: The liquid crystal molecules are arranged by the physical and chemical treatment of alignment films in such a manner that the directors, more accurately, projected images of the directors are present in substantially all directions on the plane parallel to a certain plane between two substrates or parallel to the xy plane. For example, molecules are arranged along a certain closed curve on the plane present between the two substrates so that the projected images of the directors on the closed curve continuously change to show all directions. In the projected images of the directors, the major axes of the liquid crystal molecules are controlled to be symmetric for a certain point or line, especially, to show rotational symmetry. Since compaction on the plane which is caused on a conventional liquid crystal display device is not caused, the obtd. device has a wide viewing angle and no inversion of gradation.
