On MagicGate Memory Stick

What is a Memory Stick?

Memory Stick is a compact, portable and versatile Integrated Circuit recording medium with a data capacity that exceeds a floppy disk. Memory Stick is specially designed for exchanging and sharing digital data among Memory Stick compatible products. Because it is removable, the Memory Stick can also be used for external data storage.

Sizes of Memory Stick

There are two sizes of Memory Stick: regular size Memory Stick and compact size Memory Stick Duo. With a duo adaptor, you can use Memory Stick Duo on a device supporting regular size Memory Stick. For your Network Walkman, use a Memory Stick Duo (compact size Memory Stick).

Connect the AC power adaptor.
