PURPOSE: To enhance the transfer property of an uneven configuration, by using a composition, which is prepared by homogeneously mixing an aromatic polymer derived from 2,2-bis(4-hydroxyphenyl)propane and a specific aromatic polyester in a specific ratio, as a disc base material.

CONSTITUTION: In a recording carrier wherein information pits are carved in the single surface of a disc and information is read according to an optical or electrostatic capacity system, as the disc base material, a composition, which is prepared by homogeneously mixing 99W10pts.wt. of an aromatic polymer selected from polyarylate derived from 2,2-bis(4-hydroxyphenyl)propane represented by formula I (wherein formula II is an iso-/tere-mixture), polycarbonate represented by formula II and polycarbonate represented by formula IV and 1W 90pts.wt. of an aromatic polyester selected from polyalkylene terephthalate, polycyclohexylterephthalate and polyoxyalkylene benzoate, is used.
