ABSTRACT:
An optical mother disc recording apparatus is disclosed, which can effectively solve problems including a decrease in film thickness and the like and can be miniaturized. The optical mother disc recording apparatus comprises a turntable for supporting an optical mother disc having a transparent substrate on which a photoresist layer is formed; a motor for rotating and driving the turntable; and optical means for irradiating a laser beam modulated by an information signal onto the optical mother disc, wherein the transparent substrate has a thickness within the range from 0.4 mm to 4.0 mm and a diameter within the range from 70 mm to 400 mm, and the turntable is capable of being in contact with an area on the inside and/or outside of a recording area of the optical mother disc. The outermost radius of the turntable is smaller than the innermost radius of the recording area of the optical mother disc.
