Sputtering target and manufacturing method therefor, and optical recording medium and manufacturing method therefor

摘要

To provide a sputtering target used for the formation of a recording layer of a recordable optical recording medium, wherein the sputtering target contains Bi and Fe and the packing density of the sputtering target is greater than 96%, and a recordable optical recording medium manufactured by using the sputtering target, which the recordable optical recording medium is capable of high-density recording even in the blue laser's wavelength range.
