Thinner, lighter carbon fiber notebook unveiled

16 November 2003

Sony has unveiled a carbon fiber version of its 505-series notebook computer that the company claims is the world's lightest and thinnest of its type.

One of the first things noticeable about the PCG-X505 is its thickness, which is .4 inches at the front growing to .8 inches at the back where the body and display are hinged together. Sony managed to cut down on the thickness of the machine by miniaturizing the motherboard so that it fits in a space between the keyboard, hard drive, battery, and PC Card slot, said Keiichiro Shimada, president of Sony's Vaio products research and development group.

Usually the motherboard is much larger and overlaps other components requiring the machine to be thicker, but by shrinking the motherboard down in size--to roughly the size of a Mini Disc--the company has managed to cut the total thickness of the machine, he said. Other space-saving measures include fitting the Memory Stick slot into the computer mouse and reducing the thickness of the keyboard backplane to .01 inches, Shimada said.

The computer measures 10.2 inches by 8.2 inches and weighs just 1.7 pounds with a carbon fiber case. The laptop is one of two new members of Sony's Vaio personal computer family that will serve as the company's flagship models during the upcoming year-end sales period in Japan.
