Not quite a VHS vs. Betamax sequel. But again, two consumer electronics giants find themselves in opposing camps in a format battle as they crank up production of removable flash memory cards.

Matsushita Electric Industrial Co. has announced it will raise monthly output capacity of its SD (Secure Digital) memory cards to 2.3 million units starting this month; that would be 27.6 million a year and a twofold-plus increase compared with 12 months ago.

Meanwhile, Sony Corp. shipped 19 million Memory Sticks in fiscal 2002 and expects to sell 80 million in fiscal 2005.
