Design of a high-precision disc structure Less damage from temperature and humidity changes and less disc warpage

Description
A comparison of disc warpage (inclination) when the humidity was changed from 90% to 45% under a stable temperature of 25 degrees C. The warpage of a BD is suppressed at about half of that of a CD or DVD.

Our environment is constantly changing according to the weather, temperature, and humidity. The external environment also impacts discs. Sony has reduced disc warpage by seeking a disc structure that is stable against temperature and humidity changes.

As one example, the chart to the left shows a comparison of disc warpage caused by humidity changes. It shows that the warpage on a BD is significantly lower than that of a CD/DVD. The Sony Blu-ray Disc is durable under environmental changes and suited to a wide range of usage environments.
