Abstract: Preformatted areas in at least the most distal recording layer from an object lens among a plurality of recording layers in an optical disc include guard areas at both ends of the respective recording layer in the tracing direction. No data is recorded on the guard areas. The guard area length GL is determined to satisfy the following formula:GLnullYLnullTnull(NA/n)/null1null(NA/n)2nullnullwhere YL is a maximum allowable value of position deviation between the preformatted areas in the most distal recording layer and in another recording layer in the tracing direction; NA is the numerical aperture of the object lens; T is a distance between the most distal and the another recording layer; and nullnnull is an refraction index of a medium between the most distal and the another recording layers.

Abstract: In case of manufacturing a disk having a two-layer structure, a glass substrate 13 is bonded to a cover layer 11 through an adhesive layer 12, and a mount hole 14a is formed in a center thereof to form a bonded substrate 14 having a three-layer structure (a). In a state where a stamper 15 formed a predetermined pit pattern is set to a center boss 16, the bonded substrate 14 is pressed downward in a vertical direction while the mount hole 14a of the bonded substrate 14 is aligned with the center boss 16(b). Whereby an information recording surface 11a is transferred onto the cover layer 11(c). Subsequently, after the bonded substrate 14 has been bonded to another layer substrate of the disk, the adhesive layer 12 is removed to separate the glass substrate 13. Finally, there is manufactured the disk having the two-layer structure.

Abstract: A conduction means having conduction path for injecting molten molding material within a mold space is fitted to one of a pair of mold bodies which form the disc-shaped mold space. A first heat suppressing means for suppressing heat within the conduction path from being transmitted to the one of the mold bodies is disposed between the conduction means and the one of the mold bodies. Further, a second heat suppressing means is disposed at a position opposing to the first heat suppressing means at the time of mold-clamping the pair of the mold bodies.
