Filed: 1993-11-11
Abstract: PURPOSE: To improve optical and structural characteristics by heating polymethyl methacrylate having a desired melt flow rate to a temp. of a specified range and injecting the melt for a prescribed time. CONSTITUTION: After a beam 4 is correctly formed by a lens 15, the beam passes a beam splitting prism 20 and the transmitted part is applied to a quarter-wave plate 22.

The mirror 24 directs the reading beam 4 toward a pivotal mirror 26 which in turn moves the light beam toward the degree of freedom of the motion which is the direction tangent to the surface 7 of a video disk 5. At the time of molding the disk 5, the polymethyl methacrylate having the melt flow rate within the range of 20 to 23g per 10 minutes is first prepd. The polymethyl methacrylate is then heated to the temp. within a range of 510 to 560 deg.F and is injected for the time within a range of about 0.5 to 2 seconds.  The disk 5 is then helpful as a protective transmissible layer and contributes to an improvement in the optical characteristics and the structural characteristics.
