Abstract
The manufacture of high performance Φ 130 mm magneto-optical (MO) discs requires the substrates with low retardation, high heat resistance and low cost in the market. The molding methods for newly compounded photo-curable acrylic resin (PHC) were studied. Thus, the pre-grooved substrate using PHC resin has been developed for the MO disc, and is capable of fast molding by a simple machine. Carrier to noise ratio (C/N) characteristics and the reliability of the MO disc with the PHC substrate are almost equal to those of glass substrate.
