    摘要： An objective lens holder for use in an objective lens driving device of a symmetry type has an upper member and a lower member assembled with the lower member. The lower member has a pair of main bobbin portions for winding two tilting coils and two focusing coils. The pair of main bobbin portion is symmetrically disposed with respect to an optical axis of a laser beam. The upper member and the lower member have openings for passing through the laser beam. Each of the upper member and the lower member has four hook portions for winding four tracking coils.

    摘要： A cellulose acylate film is produced by using a cellulose acylate solution and forming a film consisting of two or more layers by the co-casting method. The cellulose acylate to be used is selected so that the association molecular weight of cellulose acylate due to the static light scattering in the solution forming the outer layer becomes smaller than the association molecular weight of cellulose acylate due to the static light scattering in the solution forming the inner layer.
