Optical recording medium containing a substrate, an intermediate layer having therein an amorphous material, the intermediate layer having a reflective layer thereon

Abstract

Reduction in noise of the read out signal as well as enhanced storage reliability are realized in an optical recording medium comprising a supporting substrate, and a reflective layer, a recording layer, and a light-transmitting substrate disposed on the supporting substrate in this order. The optical recording medium comprises a supporting substrate 20, and an intermediate layer 10 comprising an amorphous material, a reflective layer 5 comprising a polycrystalline material, a recording layer 4, and a light-transmitting substrate 2 disposed on the supporting substrate in this order. The write beam and the read beam are directed through the light-transmitting substrate 2.
