FILTER FOR OPTICAL RECORDING MEDIUM, METHOD FOR MANUFACTURING SUCH OPTICAL RECORDING MEDIUM, OPTICAL RECORDING MEDIUM, METHOD FOR RECORDING IN SUCH OPTICAL RECORDING MEDIUM AND METHOD FOR REPRODUCING FROM SUCH OPTICAL RECORDING MEDIUM

摘要

A filter for an optical recording medium is characterized in that a plurality of high refraction index layers and low refraction index layers are alternately stacked, the total stacking number of the high refraction index layers and the low refraction index layers is an even number of 10-20, and the thickness of the high refraction index layer and that of the low refraction index layer are different from each other. An optical recording medium using such filter is also provided.
