Toshiba has been on a roll in recent months. In May this year, the Japanese company said it plans to spend US$18.4 billion over the next three years to build its core business including such as consumer electronics, semiconductors and nuclear power. This investment is 80 percent more than in the previous three years.

For instance, the company this year acquired U.S. nuclear fuel company Westinghouse for US$5.4 billion. The move marks Toshiba's ambitions to become a major player in the nuclear power market.

Toshiba is also the second-largest flash memory maker in the world, after South Korea's Samsung. In March, the company said it will work with storage company Sandisk, to produce more flash memory chips for cellphones and portable devices. The move comes as semiconductor makers shift their focus to flash memory production, partly fueled by the surging demand for digital music players.

The company's micro hard disk drives continue to do well, with a 31 percent share of the consumer electronics market during the fourth quarter last year. In February 2006, Toshiba surpassed worldwide cumulative production of 25 million 1.8-inch hard disk drives.

This company is listed in Systems.
