Memory Stick Micro media is approximately one-quarter the size of Memory Stick PRO Duo media, yet only about 1.2 mm thick. The media's edges are slotted lengthwise to allow for more slim-line designed connectors to reduce space in host devices. As dual-voltage media, Memory Stick Micro supports devices operating at 3.3 volts and 1.8 volts. Memory Stick Micro is designed as an externally removable media with a controlled eject function to prevent users losing the media. You will be able to insert Memory Stick Micro into an adapter for exchanging data to a Memory Stick PRO compatible product.
