Toshiba Corp. has announced the dynabook SS RX1, a line of 12.1-inch LCD widescreen notebook computers equipped with an optical disk drive, which the company claims is the world's lightest and thinnest series in a relevant category.
In addition to a standard model with an HDD, the company will launch a product with a 64 GB solid state drive (SSD) using flash memory. The HDD and SDD models weigh 959 and 848 g, respectively. They both measure 19.5 mm at the thinnest point.
The company claims that the dynabook SS RX1 boasts the longest battery life as of today in the category of 12.1-inch widescreen notebook computer weighing less than 1 kg.
When using the supplied rechargeable battery, the SSD model can run 12.5 hours. The new models will be released in order from June 22, 2007 at open prices. The street pricing is expected to be around 220,000-400,000 yen (USD 1,820-3,300).
In order to achieve lighter weight, thinner profile and longer battery life, the company has made numerous improvements such as a higher density mounting on a substrate, reduction in chassis thickness and sharing of antennas.
For example, SSD has contributed to slash power consumption. More specifically, the power consumption can reportedly be reduced by 12% when compared to the case using an HDD.
In addition, a 12.1-inch semi-transmissive widescreen LCD panel is employed. This also helps to reduce the power consumption because approximately 3 W that is otherwise consumed by the LED backlight can be saved by turning off the light when the machine is used outdoors, the company explained.
An ultrathin recordable DVD drive measuring 7 mm is employed so that the slim chassis can contain the drive. Although Toshiba does not specify the supplier of the DVD drive, it is supposedly a product from Panasonic Communications Co., Ltd. as Panasonic announced the world's first commercialization of the drive with a thickness of 7 mm.
The latest series are provided with built-in antennas for wireless communication such as 3G including CDMA and WiMAX. To reduce the footprint of the antennas, the company has employed "multiband antenna," a modified-shaped shared antenna for wireless LAN, WiMAX and 3G.
Reportedly, the total number of antennas required has been reduced from eight to five. However, a built-in communication module is not provided at the moment.
The company plans to launch the modules supporting these communication schemes as soon as the services start. A user will be required to select a module based on either 3G or WiMAX.
