Toshiba plans to show its first notebook computer with a built-in HD-DVD drive at the Ceatec Japan 2005 exhibition next month, a company spokeswoman said Tuesday.

The company will show a new addition to its high-end Qosmio notebook line that will include an integrated HD-DVD-ROM drive, according to Midori Suzuki, a spokeswoman for the company in Tokyo. The new drive will let users watch high-definition videos on their computers.

"Toshiba is planning to commercialize the product at the beginning of next year," she said.

Few details of the HD-DVD-equipped notebook have been made available ahead of the Ceatec show, which will be held near Tokyo from Oct. 4 to Oct. 8. The notebook will include a new high-resolution LCD, Toshiba said in a statement.

Suzuki declined to disclose additional details about the system.

HD-DVD is a next-generation DVD format developed by the DVD Forum. The integrated HD-DVD-ROM drive, which will be shown with the Qosmio notebook at Ceatec, is 12.7 millimeters high, according to Toshiba. The drive uses a pick-up head with a single optical lens that can read HD-DVD discs and read and write to CD and DVD discs, the company said.

Initially, HD-DVD discs will have a capacity of 30GB, Toshiba said, noting that higher capacity versions are anticipated. The company has developed a prototype HD-DVD disc with a capacity of 45G bytes.

Suzuki said Toshiba has not decided how many Qosmio models will be equipped with the HD-DVD-ROM drive and no decision has been made regarding extending availability of the drive to the company's other notebook PC lines.

The HD-DVD-ROM drive is small enough to be used in small form-factor notebooks, according to Toshiba.
