Abstract
To provide an optical recording medium of which mechanical properties and storage stability will not be impaired, and which will show little deterioration in signal properties even after being left to stand at high temperature under high humidity. An optical recording medium to perform recording/reading by means of blue laser, which has a value of 10 or less as obtained by “error rate after its environmental resistance test/error rate before its environmental resistance test” in error rates obtained before and after its environmental resistance test carried out by leaving the medium to stand for 500 hours at a temperature of 80° C. under a relative humidity of 80%.
Claims10
An optical recording medium capable of recording and reading by a blue laser, wherein the medium has a value of 10 or less for the value of an error rate after an environmental resistance test over the error rate before the environmental resistance test wherein the environmental resistance test is carried out by keeping the medium for 500 hours at a temperature of 80° C. under a relative humidity of 80%.
