VERFAHREN ZUR HERSTELLUNG EINES OPTISCHEN AUFZEICHNUNGSTRAEGERS.

摘要

An optical recording medium has a space therein and is prepared such that a pair of substrates (1a, 1b) are partially adhered by an adhesive obtained by dispersing granular or filler type spacing members therein. At least one of the substrates (1a, 1b) has an optical recording layer (2a, 2b) thereon, the recording layer (2a, 2b) faces inside and a specific gravity of the spacing member falls within a range of 0.9 to 1.3 times that of the adhesive. When applying the adhesive to part of at least one of the substrates, a mixture of the spacing members and an adhesive is stored in a tank and is supplied in a small amount in each application cycle.
