OPTICAL RECORDING MEDIA HAVING INCREASED ERASABILITY

摘要

An optical recording medium comprising one or more recording layers (30). At least one of the recording layers (30) comprising an optical phase-change memory material, the optical phase-change memory material comprising: an optical phase-change alloy; and at least one modifier element, added to the optical phase-change alloy, that increases the erasability of the optical recording medium by at least 3 dB.
