Sony and SanDisk today announced a smaller Memory Stick card format, called Memory Stick Micro, that is designed to be used with mobile phones.

The Memory Stick Micro measures 15x12.5x1.2mm - significantly smaller than the Memory Stick Duo card format, which measures 31x20x1.6mm. They will begin licensing the new card format starting next week and the first Micro cards are expected to hit the market during the first half of 2006.

The Micro card was designed to make possible more compact multimedia mobile phones. The card format has a maximum theoretical capacity of 32GB and a maximum theoretical data transfer rate of 160Mbs.

An adapter will be made available that will allow the cards to be used with any device that supports the Memory Stick Pro format.
