Founded in 1988 by Dr. Eli Harari, an internationally recognized authority on non-volatile memory technology, SanDisk has grown to become the world’s largest supplier of flash memory data storage products.

Serving both consumers (via over 100,000 retail storefronts worldwide) and original equipment manufacturers (OEMs), SanDisk designs, develops, manufactures and markets flash storage card products for a wide variety of electronic systems and digital devices. SanDisk also licenses its technology to a number of other industry-leading companies.

With flash memory’s capability for storing large amounts of data in a compact, removable format, SanDisk’s products have helped drive the exponential growth in sales of digital cameras, multi-function mobile phones, USB flash drives, and other digital consumer devices.

SanDisk;s Memory Stick PRO Duo is half the size of a standard-size Memory Stick PRO media and it offers the same technologies including high speed data transfer, built-in MagicGate, and high capacities. The Memory Stick PRO Duo is the ideal solution for the most portable devices such as pocket-size digital cameras.

Sandisk Memory Stick Duo , Main Features

Compact and Easy to Use
Similar in appearance to a stick of gum, its length is about the same as that of an AA battery used in small portable devices such as headphone players. The shape of Memory Stick is ergonomically designed for easy handling. And, unlike other flash memory cards, it is easy to distinguish the front from the back and the top from the bottom of a Memory Stick to prevent misuse or accidental loss of data. Its small size also allows development of compatible products that are compact and portable.

By attaching an adaptor, the compact Memory Stick Duo media designed especially for mobile products becomes the same size as a standard Memory Stick.

High Reliability
Memory Stick is designed to be highly resistant to shock and vibration due to its solid-state construction with no moving parts. The connector unit and pins have special features that provide reliability as described below. The shape of Memory Stick makes it easy to insert into products and ensures highly reliable exchange of data.

Memory Stick has only 10 pins with longer lengths to ensure more reliable exchange of data.

Thanks to the slanted guide grooves, dust is automatically removed when a Memory Stick is inserted into the slot.

By simply sliding the erasure prevention switch on the back of each Memory Stick, users can prevent accidental loss of important content and data.
* The erasure prevention switch is not a standard feature on all Memory Stick PRO Duo and Memory Stick Duo (MagicGate/High-Speed Data Transfer Compatible) media.

Content Versatility
Memory Stick Application formats are specified to allow seamless sharing and exchange of data among compatible products of different manufacturers.

When recording data to a Memory Stick media using a compatible device, a folder is automatically created in accordance with the data type and format. That's why various types of digital content can be stored on a single media, without the user having to pay attention to file format or folder structure.

As Memory Stick applications expand to a wider variety of areas, automatically recordable data categories are also increasing. They are recorded so as not to affect the data already stored on the media.

Features:

• Larger storage capacities (1GB, 2GB and 4GB) than standard Memory Stick cards
• High-speed data transfer rate of 15Mbps (Megabits per second)** for DVD-quality video in real time
• Advanced security with Access Control Function and MagicGate™ technology
• The fast transfer rates help prevent data loss when power is suddenly cut-off or if the media is removed accidentally
