Inventor creates glass CD
Japananese recording engineer Suenori Fukui has developed a CD made out of glass, writes the Mainichi Daily News. Though it may sound like a novelty, the use of glass has several advantages, including durability. Plastic CDs can be subject to bending or warping in areas of high heat or humidity; glass CDs should have no such problems. Also, the transparency of glass allows lasers to better penetrate the surface, resulting in higher audio quality. The one drawback to the technology is the cost, currently fixed at 98,700 yen ($831) per handmade disc. One recording is on the market: an N&F Label release of Bach's "Air on a G String." The price is expected to drop substantially as more discs are produced.
